Lenz's cult lore of the Concavity
Or like e.g. of a suicidal Nuck cult of Nucks that worshipped a form of Russian Roulette that involved jumping in front of trains and seeing which Nuck could come the closest to the train’s front without getting demapped.
Context
The A.F.R.'s origin — le Jeu du Prochain Train, the game that makes the legless bodies (n.304 has it in full) — garbled into street legend by a coke monologue. Lenz retails as rumor the true history of the wheelchair assassins whose compatriots' dog he's about to kill; the bodies-as-election thread reaches even Brighton hearsay.
