Codex
"Codex: a desperate caveful of mute exiles, and an inexplicable colony of shivering, bad-tempered monkeys."[1]
Codex is a chilly island to the north of the Unterzee, located east of Whither.
Silence
"An isle of answers."[2]
Codex is a sullen island home to a group of Mute Exiles,[3] many of whom are ex-Whithern that dared to answer instead of ask.[4][5] Some of these Exiles have a particular question that they have been trying to answer for eternity; should they find the answer to their question, they may start speaking again.[6]
There is also a small population of irritable monkeys in Codex, who maintain a mysterious shrine. They are in possession of several strange log-books, including a book that documents the Correspondence sigils dotting the landscape of Codex.[7][8] In fact, sigils can be found within the terrain of Codex as well, etched into the island's stones like fossils.[9]
An Answer: Forever hurtling towards the earth.
