"The fear of the wide black zee, and the things beyond."[1]
The Constant Companion is an enormous monster that scours the depths of the Unterzee. These beasts sense fear like a shark smells blood, and they aggressively pursue any underwater interloper with a strong scent.[2] Their carapaces are harder than steel, and broken-off pieces may fidget and emit noises even after the creature dies.[3][4]
Morphologically speaking, Constant Companions resemble a monstrously large spider, with pedipalps,[5] mandibles,[6] greenish blood,[7] and bodies covered in hair.[5] Like many species of spider, they carry their offspring on their body. These yellowish grubs appear passive, but they display dangerous viciousness, and even cunning, should they feel threatened.[8]
↑General Information, Sunless Sea"Constant Companions only appear if the player's terror is at 65 or above, and only when they are submerged."
↑Accept her gift, Fallen London"She presents you with a pair of cufflinks [...] you can hear a faint but persistent whine, like the scream of tormented metal."
↑Bring a grub aboard, Sunless Sea"The wriggling children of the Companion still cling to their parent's husk. [...] one of the small grubs pops free. [...] the curled, yellow mass wriggles [...] before whitening and falling still. A crewman [...] approaches. The grub writhes to life, burrowing into him [...] both crewman and grub are dead."
