Editing The Correspondence

Apparently even lead can burn."''<ref name="plaque">{{Citation|https://fallenlondon.wiki/wiki/Correspondence_Plaque|Correspondence Plaque|Fallen London|}}</ref></blockquote>[[File:Graffitihiero.png|alt=Several strange symbols.|thumb|The Correspondence]]

'''The Correspondence''' is a mysterious language of unknown provenance, known for its effects on the mind and its high flammability. It is related to the freezing [[The Discordance|Discordance]], another language of a perplexing nature.__forcetoc__

==Surface-Level Details==
<blockquote>''"It's much safer to keep Correspondence letters on lead sheets than on paper. But still, your study is becoming a danger to public health and sanity."''<ref name="plaque" /></blockquote>[[File:Scrawl1.png|alt=A strange sigil.|thumb|''Almost never remembered'']]
The Correspondence is an esoteric form of writing that often consists of complex sigils or pictograms.<ref name = "plaque"/> It is extremely notorious for being hazardous to both the mind and the body; the heat generated from the sigils can scorch an observer's eyebrows clean off just from studying it too closely, to say nothing of the horrifying secrets that now swim through their foolhardy mind.<ref>{{Citation|https://fallenlondon.wiki/wiki/Ask_someone_else_what_they_saw|Ask someone else what they saw|Fallen London|}}</ref> Due its high flammability, it is often inscribed on lead plaques for study,<ref name = "plaque"/> though fireproof paper is sometimes employed as well.<ref>{{Citation|https://fallenlondon.wiki/wiki/Flame-proof_Missive|Flame-proof Missive|Fallen London|}}</ref> It's also occasionally graffitied on the walls of [[Fallen London]], causing public discontent,<ref>{{Citation|https://fallenlondon.wiki/wiki/City_Vices:_Orthographic_Infection|City Vices: Orthographic Infection|Fallen London|}}</ref> and such acts of vandalism are often dealt with by the [[Special Constables]].<ref name = "answer to nightmares">{{Citation|https://fallenlondon.wiki/wiki/The_answer_to_Nightmares%3F|The answer to Nightmares?|Fallen London|}}</ref>

Besides the occasional scribblings of the lost or confused,<ref name = "alphabet of scars">{{Citation|https://fallenlondon.wiki/wiki/An_Alphabet_of_Scars|An Alphabet of Scars|Fallen London|}}</ref> this strange language can be found in many locations throughout the [[Neath]]: from the dark spires of the [[Bazaar]],<ref>{{Citation|https://fallenlondon.wiki/wiki/Further_investigations|Further investigations|Fallen London|}} ''"[...] through the city to the glistening black spires of the Bazaar [...]"''</ref> to the furthest corners of the [[Unterzee]], including the skin of the [[Dawn Machine]] and the stones near the [[Avid Horizon]].<ref>{{Citation|https://sunlesssea.fandom.com/wiki/Dawn_Machine|Dawn Machine|Sunless Sea|}}</ref><ref>{{Citation|https://sunlesssea.gamepedia.com/Avid_Horizon|Avid Horizon|Sunless Sea|}}</ref> It can commonly be seen in several places across the [[High Wilderness]] as well, such as at the [[Most Serene Mausoleum]],<ref>{{Citation|https://sunlessskies.fandom.com/wiki/Correspondence_Sigil_in_the_Most_Serene_Mausoleum#Interaction_description|Interaction description|Sunless Skies|}}</ref> the chaotic region of [[Pan]],<ref>{{Citation|https://sunlessskies.fandom.com/wiki/Correspondence_Sigil_in_Pan#Interaction_description|Interaction description|Sunless Skies|}}</ref> and other odd corners of the sky.

<blockquote>''"A new one! What does it mean? 'Tracks in the illimitable void?' Is it that character that translated as an emotion somewhere between love and academic excitement?

Those clever or foolhardy enough to study the Correspondence in detail are called '''Scholars of the Correspondence'''.<ref>{{Citation|https://fallenlondon.wiki/wiki/A_Scholar_of_the_Correspondence|A Scholar of the Correspondence|Fallen London|}}</ref> These smoldering academics are few in number,<ref>{{Citation|https://fallenlondon.wiki/wiki/Discuss_the_Discordance|Discuss the Discordance|Fallen London|}} ''"[...] how many Scholars of the Correspondence [...] there aren't too many [...]"''</ref> and have a tendency to frantically study any sigils they can get their eyes on, safety and sanity notwithstanding.<ref>{{Citation|https://fallenlondon.wiki/wiki/What%27s_that%3F|What's that?|Fallen London|}}</ref> They commonly frequent the [[Forgotten Quarter]], as it is littered with searing artifacts.<ref>{{Citation|https://fallenlondon.wiki/wiki/Set_of_Correspondence_Stones|Set of Correspondence Stones|Fallen London|}}</ref> The [[University]] also has an unnamed department dedicated to studying the Correspondence, though they prefer to practice restraint when handling the language, and shy away from handling the Correspondence directly.<ref>{{Citation|https://fallenlondon.wiki/wiki/What_were_they_up_to%3F|What were they up to?|Fallen London|}}</ref> It is considered extremely dangerous to study this language on the [[Surface]], as it is outside the safe confines of the [[Neath]].<ref name = "remember something useful">{{Citation|https://fallenlondon.wiki/wiki/Perhaps_you_can_remember_something_useful|Perhaps you can remember something useful|Fallen London|}}</ref> 
[[File:Monosigil.png|alt=A monocle inscribed with a strange sigil.|thumb|A Semiotic Monocle.]]
Unsurprisingly, studying the Correspondence can be difficult even for the experienced academic. Works regarding the Correspondence are often fiercely hoarded by collectors or are outright destroyed by the [[Ministry of Public Decency]],<ref>{{Citation|https://fallenlondon.wiki/wiki/A_distinctly_cautious_approach|A distinctly cautious approach|Fallen London|}} ''"[...] between private collectors, [...] the Ministry of Public Decency [...]"''</ref> and lengthy discussions regarding the Correspondence in detail can be extremely detrimental to all parties involved.<ref name = "find out what he knows">{{Citation|https://fallenlondon.wiki/wiki/Find_out_what_he_knows|Find out what he knows|Fallen London|}} ''"Your philologist is not what he was: [...] talking to him difficult."''</ref> In fact, just ''thinking'' about the Correspondence can result in feelings of being scorched.<ref>{{Citation|https://fallenlondon.wiki/wiki/The_Correspondence_Savages_Your_Dreams|The Correspondence Savages Your Dreams|Fallen London|}}</ref> Thus, common methods for studying the Correspondence include direct field research: learning new sigils, studying uncovered sigils in detail,<ref name = "look for evidence of correspondence ruins"/> or sleeping on Correspondence-inscribed artifacts.<ref name = "incautious approach">{{Citation|https://fallenlondon.wiki/wiki/A_decidedly_incautious_approach|A decidedly incautious approach|Fallen London|}}</ref> Scholars also use unique devices, such as '''Semiotic Monocles''', to study the Correspondence safely,<ref>{{Citation|https://fallenlondon.wiki/wiki/Semiotic_Monocle|Semiotic Monocle|Fallen London|}}</ref> and especially advanced academics may experiment with lead Correspondence Plaques, at the presumed detriment of their long-term health.<ref name = "remember something useful"/>

The Correspondence is the language of the [[Judgements]] - the stars, like the [[Sun]].<ref name = "mysteries of heavens"/> These sky-gods use the Correspondence to communicate amongst themselves, using [[Messengers]] like the [[Bazaar]] and the now-deceased [[House of Rods and Chains]] to correspond with one another,<ref>{{Citation|https://fallenlondon.wiki/wiki/Order_Ovate,_Ice|Order Ovate, Ice|Fallen London|}}</ref><ref>{{Citation|https://sunlessskies.fandom.com/wiki/The_House_of_Rods_and_Chains#Log_Entries|Log Entries|Sunless Skies|}}</ref> and to ensure that their messages are not forgotten, Messengers inscribe the Correspondence on their carapaces.<ref>{{Citation|https://fallenlondon.wiki/wiki/Ambition:_Nemesis_%E2%80%93_One_Last_Matter|Ambition: Nemesis %E2%80%93 One Last Matter|Fallen London|}}</ref><ref>{{Citation|https://fallenlondon.wiki/wiki/Warm_your_Tears_of_the_Bazaar|Warm your Tears of the Bazaar|Fallen London|}} ''"You have scored the message on your skin so you will not forget."''</ref> Correspondence sigils can also manifest directly on a star's surface, dimming their brightness somewhat and appearing very similar to sunspots.<ref>{{Citation|https://sunlessskies.fandom.com/wiki/Within_a_Weft_of_Unravelling_Time#Interactions|Search the past for a lost Correspondence sigil|Sunless Skies|}}</ref>

=== Lawful Light ===
<blockquote>''"Sunlight is - in certain senses literally, quite literally, law. Without sunlight, the earth would spin off into space. And the absence of sunlight down here means the absence of a dozen laws. Death operates unreliably (though more reliably on the zee, as you know). Geography is uncertain and shifting. And dreams - dreams - "''<ref name="chat about science">{{Citation|https://sunlesssea.fandom.com/wiki/Haunted_Doctor#Interactions|Chat about science|Sunless Sea|}}</ref>

''"Mathematics. Formulae. Principles that dictate how the planets move, how apples fall, how confessions can be compelled. How confessions can be compelled: the same way apples fall, and planets move. Apply the right force. Ask the proper question. The effect will follow the cause. Whoever you interrogate will speak the truth, because in the language that governs the stars, there is only the truth."''<ref name="cricket anyone">{{Citation|https://fallenlondon.wiki/wiki/Cricket,_Anyone%3F_(Story)|Cricket, Anyone? (Story)|Fallen London|}}</ref></blockquote>[[File:Deathsdoorstep ambience.png|thumb|150px|alt = A door in the sky opening to reveal a star.|[[Death's Door]]]]
Many forms of the Correspondence are in fact a form of law, and Judgements use the Correspondence to enforce and maintain their celestial principles.<ref>{{Citation|https://fallenlondon.wiki/wiki/Cricket,_Anyone%3F_(Story)|Cricket, Anyone? (Story)|Fallen London|}} ''"A law is a sequence of words, [...] Correspondence blazes in your brain. You perceive laws [...]"''</ref><ref name = "mysteries of heavens"/> Certain manifestations of the Correspondence are indistinguishable from light,<ref name = "chuckle">{{Citation|https://fallenlondon.wiki/wiki/A_Conversation_on_the_Road|A Conversation on the Road|Fallen London|}} ''"A chuckle in the Correspondence is the crackle of broken light."''</ref> so a Judgement's starlight can easily subjugate anything it reaches to its will, with the finality and certainty of a deity.<ref>{{Citation|https://sunlessskies.fandom.com/wiki/The_Sapphir'd_King#Interactions|Pledge your allegiance|Sunless Skies|}}</ref> With a single flare, a Judgement can impose on its subjects any law it chooses, including laws that determine the rules of [[Death|mortality]], the stability of geography, the nature of [[Parabola|dreams]],<ref name = "chat about science"/> or even the definition of existence itself.<ref>{{Citation|https://sunlessskies.fandom.com/wiki/Beyond_Death's_Door#Interactions|Rage against the light of dying|Sunless Skies|}}</ref> 

The forms of law that the Judgments enforce can range from laws defining gravity, to the trajectory of planetary orbits, to the method of proper interrogation, but they all have a core theme at heart: every sigil of celestial law defines a strict cause and an effect, because in celestial law, there is no flexibility or uncertainty; only truth.<ref>{{Citation|https://fallenlondon.wiki/wiki/Cricket,_Anyone%3F_(Story)|Cricket, Anyone? (Story)|Fallen London|}} ''"[...] your head is brimming with celestial law. [...] Principles that dictate how the planets move, how apples fall, how confessions can be compelled.
[...] The effect will follow the cause. [....] in the language that governs the stars, there is only the truth."''</ref>

Sometimes, the Judgements need active enforcement for certain tasks or interpretations of their laws. To this end, they may create [[Logoi]], living sigils of the Correspondence that are effectively immortal and carry out their duties with fury and gusto.<ref>{{Citation|https://sunlessskies.fandom.com/wiki/Red_Logos|Red Logos|Sunless Skies|}}</ref>

== Applications ==
<blockquote>''"It's probably safe to weld Correspondence Plaques to the stove's bottom. After all, the stove is metal; the plaques are metal; if one hasn't caught fire, the other shouldn't. And even if there were a fire, isn't that the idea?"''<ref name="reinforce the stove">{{Citation|https://fallenlondon.wiki/wiki/Reinforce_the_potbelly_stove|Reinforce the potbelly stove|Fallen London|}}</ref></blockquote>[[File:Searingenigma.png|150px|alt=A piece of burning paper inscribed with odd sigils.|thumb|A Searing Enigma.]]
As one of the most all-encompassing and versatile languages in the universe, it's not surprising that the Correspondence has a variety of surprisingly practical applications. Naturally, its most obvious use is allowing communication between two highly disparate parties,<ref name = "search it for letters of fire">{{Citation|https://fallenlondon.wiki/wiki/Search_it_for_letters_of_fire|Search it for letters of fire|Fallen London|}}</ref> or convey concepts that cannot be easily explained in lesser tongues.<ref name = "become correspondent">{{Citation|https://fallenlondon.wiki/wiki/Become_a_Correspondent|Become a Correspondent|Fallen London|}}</ref> 

Unlike most languages, which reflect the world and order thoughts, the Correspondence is capable of ''shaping'' the world and ''composing'' thoughts of its own accord.<ref>{{Citation|https://fallenlondon.wiki/wiki/Read_the_Doctor%27s_writings|Read the Doctor's writings|Fallen London|}} ''"[...] of the Correspondence [...] Such an alphabet shapes the world around it, rather than reflecting it; it is no mere method of ordering thoughts, it composes and creates them of its own accord."''</ref> The meanings of sigils of the Correspondence that represent concepts can be especially notable, as they can be used to convey certain characteristics onto the objects upon which they're written. For instance, carefully inscribing the Correspondence sigils for "Light" and "Constancy" onto a waxen cylinder can create a candle that never loses its flame.<ref name = "create candle">{{Citation|https://fallenlondon.wiki/wiki/Create_your_own_Candle|Create your own Candle|Fallen London|}}</ref><ref>{{Citation|https://fallenlondon.wiki/wiki/Everlasting_Candle|Everlasting Candle|Fallen London|}}</ref> Furthermore, the influence of an inscribed sigil may extend far beyond the object on which it was inscribed; the entirety of [[Langley Hall]], for example, is under the influence of an alluring Correspondence sigil seared onto the body of the eponymous Lord Langley, giving the Hall its infamously hypnotic properties.<ref>{{Citation|https://sunlessskies.fandom.com/wiki/The_Ballroom#Interactions|Ask Lord Langley about the Hall|Sunless Skies|}}</ref>

But sometimes the ''meaning'' of the Correspondence isn't as important as the ''properties'' of the Correspondence. Naturally, its most well-known property is its ability to generate large amounts of thermal energy, and as such the Correspondence can be used as an extremely powerful heat source. When used correctly, it can also generate a form of smokeless combustion.<ref>{{Citation|https://fallenlondon.wiki/wiki/Practical_application_of_esoteria|Practical application of esoteria|Fallen London|}}</ref> However, using the Correspondence for this purpose can be dangerous, as the resulting fires can be highly volatile and difficult to control.<ref>{{Citation|https://sunlessskies.fandom.com/wiki/Adrift!#Interactions|Inscribe a Searing Enigma upon your regulator valve|Sunless Skies|}}</ref>
[[File:Sigilriddennavigator.png|thumb|alt = A man with a large sigil on his forehead.|100px|[[The Sigil-Ridden Navigator]]]]
The Correspondence's uses go beyond mere communication and esoteric engineering, however. When in the hands of a truly unscrupulous individual, the Correspondence can be used to push the very boundaries of reality. Sigils of the Correspondence can grant false life to flesh, enter dangerous pacts in exchange for service,<ref>{{Citation|https://sunlesssea.fandom.com/wiki/Kingeater%27s_Castle#Interactions|Rid your Sigil-Ridden Navigator of his troublesome humanity|Sunless Sea|}}</ref> be used to inflict tremendous amounts of torment on the unwary or unfortunate,<ref>{{Citation|https://sunlessskies.fandom.com/wiki/The_Confessional#Interactions|Open the second door|Sunless Skies|}}</ref> or prove useful in other dark quests.<ref name = "alphabet of scars"/> In fact, one of the most powerful uses of the Correspondence is its ability to manipulate time, space, and causality. With the right sigils, the Correspondence can untangle space and restore nearby surroundings to a prior state, though of course, such endeavors are no easy task, and may require entire teams of dedicated Correspondents to execute correctly.<ref>{{Citation|https://fallenlondon.wiki/wiki/Arrange_with_Furnace_to_repair_the_missing_block|Arrange with Furnace to repair the missing block|Fallen London|}} ''"[...] four Correspondents write [...] inscribe the equation that unknots space. [...] row-houses [...] have returned, but [...] in a pre-demolished condition."''</ref>

=== Paradoxical ===
<blockquote>''"There is no law: that is the law. Heat something, melt it, reshape it. Translate it into something new. Even the truth is mutable. Even the words you're reading aren't the words you're reading now. You scan the last sentence again. It's different. You flip to the index. There is no index. Page numbers change. Your head begins to pound."''<ref name="cricket anyone">{{Citation|https://fallenlondon.wiki/wiki/Cricket,_Anyone%3F_(Story)|Cricket, Anyone? (Story)|Fallen London|}}</ref></blockquote>[[File:Mementomori.png|thumb|alt = A piece of machinery with sigils inscribed on it.|The Memento Mori]]
Even a language as ancient and esoteric as the Correspondence isn't immune to the concept of paradox; there exist self-contradictory, nonsensical, or illogical forms of the Correspondence. These mysterious laws are so paradoxical that they barely even resemble "laws" at all, but they burn all the same, and they embody the inherent mutability of language, truth, and the universe.<ref>{{Citation|https://fallenlondon.wiki/wiki/Cricket,_Anyone%3F_(Story)|Cricket, Anyone? (Story)|Fallen London|}} ''"There is no law: that is the law. [...] Even the truth is mutable. [...] Page numbers change. [...] To rise is to fall. Smoke coils from the crawling print."''</ref> 

As such, sigils of the Correspondence are as capable of distorting the universe as structuring it; for example, they can be used to encode [[Treacheries]], or critical fractures in the order of the world, when properly "trained into defiance".<ref>{{Citation|https://fallenlondon.wiki/wiki/Finish_your_work_resizing_a_human_ribcage_using_the_Red_Science|Finish your work resizing a human ribcage using the Red Science|Fallen London|}}</ref><ref>{{Citation|https://fallenlondon.wiki/wiki/St_Erzulie%27s_Candle_(Action)|St Erzulie's Candle (Action)|Fallen London|}}</ref> Thus, the Correspondence is a crucial tool in the study of [[Red Science]],<ref>{{Citation|https://sunlesssea.fandom.com/wiki/Visit_to_the_Smith%27s_Emporium|Ask the smith to construct an assembly-housing for the Cannoneer's weapon|Sunless Sea|}}</ref> the practice of breaking old chains and forging new links.<ref>{{Citation|https://fallenlondon.wiki/wiki/Artisan_of_the_Red_Science|Artisan of the Red Science|Fallen London|}}</ref>

== Practitioners ==
<blockquote>''"A jolly devil approaches you with a wager on the outcome of the match. If Benthic XI win, you receive an ancient text concerning the Correspondence. If the Brass Embassy Ladies win, you must publicly punch the Summerset chaplain."''<ref name="merry wager">{{Citation|https://fallenlondon.wiki/wiki/A_merry_wager|A merry wager|Fallen London|}}</ref></blockquote>[[File:Devil.png|thumb|alt = An individual with a nice hat and fangs.|A [[Devil]].]]
Besides humans and the [[Judgements]], there exist many wielders of the Correspondence from all corners of the universe. The [[Masters of the Bazaar]] occasionally speak it among themselves,<ref name = "opine">{{Citation|https://fallenlondon.wiki/wiki/A_Conversation_on_the_Road|A Conversation on the Road|Fallen London|}} ''"([...] would opine, were he speaking in air, in a language less [...] than the Correspondence.)"''</ref> and the [[Lorn-Flukes]] and [[Mt Nomad]] are capable of weaponizing it to devastating effect.<ref>{{Citation|https://sunlesssea.fandom.com/wiki/Lorn-Fluke#Behavior|Behavior|Sunless Sea|}}</ref><ref>{{Citation|https://sunlesssea.fandom.com/wiki/Mt_Nomad#Game_Data|Game Data|Sunless Sea|}}</ref> Mysteriously, eyes blessed by the Correspondence are also often sought by [[sorrow-spiders|spider-councils]].<ref>{{Citation|https://fallenlondon.wiki/wiki/Talk_your_way_out|Talk your way out|Fallen London|}}</ref>

[[Devils]] are also very knowledgeable of the Correspondence,<ref>{{Citation|https://fallenlondon.wiki/wiki/Cricket,_Anyone%3F_(Story)|Cricket, Anyone? (Story)|Fallen London|}} ''"I taught her how to speak the Correspondence through cricket."''</ref> and they utilize it in some of their highly advanced technologies, such as in their reliable devil-killing execution devices.<ref>{{Citation|https://fallenlondon.wiki/wiki/Tauroktonos|Tauroktonos|Fallen London|}} ''"The sigil is incandescent. [...] The Deviless pulls the lever. The sizzling brand descends."''</ref>  

=== Correspondents ===
<blockquote>''"The Correspondent writes with a pen of fire and a hand of adamant. No topic is beyond his consideration, no subject too fundamental or necessary to be critiqued. He has, with a single essay, destroyed a religion, started a war, or shaken the earth."''<ref name="become correspondent" /></blockquote>[[File:Violant.png|thumb|alt = A pot of strange-colored ink.|A Pot of Violant Ink.]]
'''Correspondents''' are professionals in the Correspondence who specialize in world-changing academics.<ref name = "become correspondent"/> These individuals tackle topics no one dare question, or topics typically taken for granted, and flip them on their heads, causing upheavals across certain circles and outrage among others. Unfortunately, their publications are often considered to be too advanced for the average reader, so they're unpopular to most audiences.<ref name = "become correspondent"/> Correspondents are also experts in wielding the Correspondence for their own ends, such as to convey their reputation,<ref>{{Citation|https://fallenlondon.wiki/wiki/Rely_on_your_professional_standing|Rely on your professional standing|Fallen London|}}</ref> make demands,<ref>{{Citation|https://fallenlondon.wiki/wiki/Expand_your_workshop_via_persuasion|Expand your workshop via persuasion|Fallen London|}}</ref> play politics, or other tremendous feats.<ref name = "become correspondent"/> 

The ink Correspondents prefer to use is [[violant]], the color of troublesome but necessary connections,<ref name = "pot of violant ink">{{Citation|https://fallenlondon.wiki/wiki/A_Pot_of_Violant_Ink|A Pot of Violant Ink|Fallen London|}}</ref> as violant ink is the one of the best inks for conveying the connection between meaning and symbol.<ref>{{Citation|https://fallenlondon.wiki/wiki/Discordant_Studies_(Storylet)|Discordant Studies (Storylet)|Fallen London|}} ''"You're using Violant Ink instead, which is better at capturing the connections between symbols and their meanings."''</ref> Apparently, it tastes like pitch with a hint of tears.<ref name = "pot of violant ink"/>

== Spelling and Grammar ==
<blockquote>''"You walk through the city to the glistening black spires of the Bazaar. Your studies have advanced to the point that you understand a little of the grammar of the Correspondence."''<ref name="further investigations">{{Citation|https://fallenlondon.wiki/wiki/Further_investigations|Further investigations|Fallen London|}}</ref></blockquote>Like all languages, the Correspondence has rules regarding grammar, spelling, and structure. Like the rest of the Correspondence, these rules can be unintuitive or hard to understand.<ref name = "further investigations"/>

=== Sigils and Sentences ===
<blockquote>''"Some sigils are known and frequently attested. Some can be guessed, assembled from other marks. Some are hapax legomena, seen once in the corpus and never again. And some marks can only be definitely identified as Correspondence when you write them on a page and discover that they burn."''<ref name="speculate on meaning">{{Citation|https://fallenlondon.wiki/wiki/Speculate_on_meaning|Speculate on meaning|Fallen London|}}</ref></blockquote>[[File:Merch correspondence.png|thumb|alt = Several strange sigils.|Eight sigils?]]
Certain sigils of the Correspondence are well-known and frequently prove useful, while others are hapax legomena, meaning they're seen once and never used anywhere else. Notably, some sigils can only be identified as such by their tendency to burn.<ref name = "speculate on meaning"/> Sigils can be constructed from scratch by assembling them from other marks,<ref name = "speculate on meaning"/> while others can be created from several sigils overlaid on top of one another.<ref>{{Citation|https://fallenlondon.wiki/wiki/A_partial_tale,_about_revenge_satisfied|A partial tale, about revenge satisfied|Fallen London|}}</ref> Certain sigils can also act as '''root-sigils''', from which other sigils are derived.<ref>{{Citation|https://fallenlondon.wiki/wiki/The_Gift_(Story)|The Gift (Story)|Fallen London|}} ''"[...] a Correspondence sign. [...] all those whose sign is descended from the root-sigil [...]"''</ref>

Sigils of the Correspondence are usually interpreted as having one meaning, but sometimes, they can take on several meanings depending on the context. For instance, the [[Pansekritis]] is a [[Logos]] that can mean "Eternal dominion", "Everything in its place", or even "No drop-in meetings permitted".<ref name = "listen to rumors about pansekritis">{{Citation|https://sunlessskies.fandom.com/wiki/The_House_of_Days#The_Antechamber_of_the_Pansekritis|Listen to rumours about the Pansekritis|Sunless Skies|}}</ref> Furthermore, certain sigils of the Correspondence may take on different meanings based on their orientation; for example, one sigil means "to circle a point without reaching the point" when turned sideways, and "always looking toward the horizon" when upside-down.<ref>{{Citation|https://fallenlondon.wiki/wiki/Study_the_Discordance_with_her|Study the Discordance with her|Fallen London|}} ''"This one means 'to circle a point without reaching the point', but only when it's turned sideways. [...] when it's upside down, it means 'always looking toward the horizon' instead."''</ref> Correspondence sigils that are reflected in [[Parabola]] are described as "left-handed" and said to take on a "darker meaning", though the precise implications of this are unknown.<ref>{{Citation|https://fallenlondon.wiki/wiki/Ambition:_Bag_a_Legend!_-_The_Reflection_of_the_Chorister%27s_Bomb|Ambition: Bag a Legend! - The Reflection of the Chorister's Bomb|Fallen London|}}</ref>

Sentences of the Correspondence can sometimes be hard to define; sigils of the Correspondence that are near one another can sometimes be unrelated to one another, and sentences can span long distances and be spaced far apart.<ref>{{Citation|https://fallenlondon.wiki/wiki/Further_investigations|Further investigations|Fallen London|}} ''"Symbols close to each other may be [...] unrelated. [...] a ‘sentence’ can span four levels of three different spires."''</ref> However, only a maximum of six sigils can be written safely on a single surface; seven sigils tend to burst into flame and destroy the surface they're written on.<ref>{{Citation|https://fallenlondon.wiki/wiki/Lost_in_Reflections|Lost in Reflections|Fallen London|}} ''"[...] it bears six words of the Correspondence, and no document [...] can bear a seventh.

<blockquote>''"In tandem, at the striking of the clock, four Correspondents write on the paving, 'return from exile', with the punctuation mark that renders the sigil into a command."''<ref name="arrange with furnace repair missing block">{{Citation|https://fallenlondon.wiki/wiki/Arrange_with_Furnace_to_repair_the_missing_block|Arrange with Furnace to repair the missing block|Fallen London|}}</ref></blockquote>[[File:Rockcorrespondence.png|thumb|alt = A stone covered in strange inscriptions.|A Starstone Demark.]]
Punctuation in the Correspondence can be especially useful for parsing or using the Correspondence accurately. A certain punctuation mark can render a sigil into a command,<ref>{{Citation|https://fallenlondon.wiki/wiki/Arrange_with_Furnace_to_repair_the_missing_block|Arrange with Furnace to repair the missing block|Fallen London|}} ''"[...] the punctuation mark that renders the sigil into a command."''</ref> and mysterious stones called '''Starstone Demarks''' are said to act as punctuation in the Correspondence, as well as weapons, tokens, and punchlines.<ref>{{Citation|https://fallenlondon.wiki/wiki/Starstone_Demark|Starstone Demark|Fallen London|}}</ref>

The Correspondence is capable of encoding idioms and accents,<ref>{{Citation|https://fallenlondon.wiki/wiki/Enter_the_lighthouse.|Enter the lighthouse.|Fallen London|}} ''"[...] in a debased idiom of the Correspondence you can hardly make out."''</ref><ref>{{Citation|https://fallenlondon.wiki/wiki/For_A_Dream_Of_Innocence|For A Dream Of Innocence|Fallen London|}} ''"It will spit Correspondence words with accents improper to its station."''</ref> and its also susceptible to its own form of "slang": unique, external forms of language disguised with celestial syntax that do not fit standard Correspondence, but superficially appear to.<ref>{{Citation|https://fallenlondon.wiki/wiki/Caveat_Emptor|Caveat Emptor|Fallen London|}} ''"It adheres to no semiotic tradition that you can identify. Perhaps it's not a law [...] but rather something camouflaged with a celestial syntax [...] slip into sentences as though it belongs. [...] it can never belong."''</ref>

The Correspondence is also capable of representing numbers, quantities, and tallies, especially large ones.<ref>{{Citation|https://fallenlondon.wiki/wiki/A_distinctly_cautious_approach|A distinctly cautious approach|Fallen London|}} ''"[...] you're getting the hang of the numbering system."''</ref><ref>{{Citation|https://fallenlondon.wiki/wiki/The_Sleeper|The Sleeper|Fallen London|}} ''"[...] made themselves into sigils of the Correspondence, naming the tally of the debt [...]"''</ref> Furthermore, it has applications in esoteric forms of math and strange equations, but it may also produce unpredictable results.<ref>{{Citation|https://fallenlondon.wiki/wiki/Ask_her_to_help_with_ordinary_research_(Lettice)|Ask her to help with ordinary research (Lettice)|Fallen London|}}</ref>

Names in the Correspondence are special; they're designated with a unique superscript,<ref name = "in your dreams voice echoing">{{Citation|https://fallenlondon.wiki/wiki/In_your_dreams,_you_hear_a_voice_echoing_hollowly_each_night|In your dreams, you hear a voice echoing hollowly each night|Fallen London|}}</ref> and have strange interactions when inserted into equations.<ref>{{Citation|https://fallenlondon.wiki/wiki/Use_what_you_know_of_the_unknowable|Use what you know of the unknowable|Fallen London|}} ''"Correspondence names that inhabit the equations and transform them into entirely [...]"''</ref> Some names, usually those which are secret or forbidden in some way, are represented with seven letters, such that they cannot be safely written. [[Mr Eaten|One such Name]] drives its Seekers mad and its pursuit is strongly discouraged,<ref>{{Citation|https://fallenlondon.wiki/wiki/Seeking_Mr_Eaten's_Name|Seeking Mr Eaten's Name|Fallen London|}} ''"Why? In God's name, why? What can you possibly hope to gain? Stop now. Before it's too late."''</ref> while the [[Salt|Name-Which-Burns]] has exactly the properties one might expect.<ref>{{Citation|https://sunlesssea.fandom.com/wiki/Letters_of_the_Name-Which-Burns#Journal_description|Journal description (7)|Sunless Sea|}}</ref>

=== Sequences and Mediums ===
<blockquote>''"A law is a sequence of words, and words are simply meanings translated: by lines on a page, by sounds in a mouth, by movements across a ballroom. Or a cricket field. Correspondence blazes in your brain."''<ref name="cricket anyone" /></blockquote>[[File:Cricket.png|alt=Wickets and a cricket ball.|thumb|Cricket, anyone?]]
Writing the Correspondence is in fact only one of the many ways to express it. It can be conveyed through speech,<ref name = "opine"/> and when spoken, it may take on the form of light,<ref name = "chuckle"/> or form sigils in the air. However, speaking the Correspondence can be extremely scarring,<ref>{{Citation|https://sunlesssea.fandom.com/wiki/Kingeater%27s_Castle#Interactions|Speak your name|Sunless Sea|}}</ref> even destroying a speaker's voice and filling their lungs with blood.<ref>{{Citation|https://fallenlondon.wiki/wiki/My_Kingdom_for_a_Pig|My Kingdom for a Pig|Fallen London|}} ''"He will scream [...] his voice is gone [...] his lungs are filled with blood [...] the void between the stars opens between his teeth."''</ref>

[[Devils]], such as those of the [[Well of the Wolf]], are skilled in using song and dance to convey the Correspondence. Their dances can form patterns resembling the Correspondence, and they may sing hymns to convey inflection.<ref>{{Citation|https://sunlessskies.fandom.com/wiki/The_Bandstand#Interactions|Decipher some of the dance-alphabet of the devils|Sunles Skies|}}</ref> Musical instruments can also convey sigils of the Correspondence, but such a performance may require strange instruments and stage arrangements, such as glass drums or bassoon players that hang from the ceiling - to say nothing of the chaos that may ensue.<ref>{{Citation|https://fallenlondon.wiki/wiki/Somewhat_challenging_music|Somewhat challenging music|Fallen London|}} ''"[...] it wasn't as hard as acquiring the glass drums that your piece requires [...] the bassoon players dangling from the ceiling [...]"''</ref>

In fact, ''any sequence'' of defined events, from writing, speech, dance, or any other action, can be a form of the Correspondence, as "actions" are sequences of events, "laws" are sequences of words, and "words" are simply meanings translated into a suitable medium.<ref>{{Citation|https://fallenlondon.wiki/wiki/Cricket,_Anyone%3F_(Story)|Cricket, Anyone? (Story)|Fallen London|}} ''"A law is a sequence of words, and words are simply meanings translated: by lines on a page, by sounds in a mouth, by movements across a ballroom. [...] You perceive laws, not as words, but actions."''</ref> Thus, even something as unorthodox as ''cricket'' can serve as a medium for the Correspondence: the bat, a pen; the ball, a punctuation mark; and the universe, the paper.<ref>{{Citation|https://fallenlondon.wiki/wiki/Cricket,_Anyone%3F_(Story)|Cricket, Anyone? (Story)|Fallen London|}} ''"[...] the ball: a point in space, a punctuation mark. [...] your bat is the pen [...] this universe is the paper [...] </ref>

== Compilations ==
<blockquote>''"With pen, paper, and a hardback copy of Dolford's Compilation, you subject your transcription to a merciless interrogation. You use a magnifying glass at several points, until it melts entirely."''<ref name="begin your translation">{{Citation|https://sunlessskies.fandom.com/wiki/Perform_a_Translation#Interactions|Begin your translation|Sunless Skies|}}</ref></blockquote>There exist several compilations of the Correspondence, and given their contents, many of them need to be handled with care. One such compendium is the '''Gulbahar Redaction''', a four-volume book consisting of sigils deemed forbidden by the [[Ministry of Public Decency]].<ref name = "decipher scathewick correspondence">{{Citation|https://fallenlondon.wiki/wiki/Decipher_Scathewick%27s_Correspondence_sign|Decipher Scathewick's Correspondence sign|Fallen London|}}</ref> Another compilation is titled '''Guttering Embers: a Study of Three Abandoned Branches of the Chiswick-Myers Semagramic Tree'''.<ref>{{Citation|https://fallenlondon.wiki/wiki/Decipher_Scathewick%27s_Correspondence_sign|Decipher Scathewick's Correspondence sign|Fallen London|}} ''"You check Guttering Embers: a Study of Three Abandoned Branches of the Chiswick-Myers Semagramic Tree [...]"''</ref> Yet another compilation is the '''Dolford Compilation''', which notably contains designations for dangerous sigils, called '''Regrettable''', and includes threat levels for them, the most dangerous of which are termed '''conflagratory'''.<ref>{{Citation|https://sunlessskies.fandom.com/wiki/To_Become_Fire_Rather_Than_Be_Burned#Interactions|Store the sigil safely|Sunless Skies|}}</ref>

== Real-Life Inspirations ==
Correspondence tablets may have been inspired by Greco-Roman curse tablets, which were pieces of lead or pewter inscribed with curses against specific people (e.g. thieves).<ref>{{Citation|http://curses.csad.ox.ac.uk/beginners/index.shtml|Curse Tablets from Roman Britain|Center for the Study of Ancient Documents, Oxford University|}}</ref> It's possible that they were also inspired by cuneiform, Egyptian hieroglyphics, or Mayan hieroglyphics, all three of which have strong ties to ''Fallen London''<nowiki/>'s story as the writing systems of the first three [[The Fallen Cities|fallen cities]].

The sigil "The act of drowning your sister to be with the one she loves, although you do not share that love" is a reference to the folksong The Twa Sisters.
