Utropolis

Utropolis is the fictional version of Rapture created by Lex Harlan and the editors of Visionary Wonders when editing the writings of RØd Killian Quain (formerly known as Orrin Oscar Lutwidge). His stories describe a technologically advanced city at the bottom of the ocean which Harlan called Utropolis. Other changes to his writing including changing splicers to juicers, ADAM to transformula, Big Daddies to Patri-Arkhs, Apollo Square to Mithra Square, and most interestingly, Little Sisters were changed to little chipmunks, which is a reference to early concept art from Bioshock 1 before they conceived of Little Sisters and were trying to create a creature that players would find sympathetic.

Lex Harlan would always leave hints to the readers that these were true stories, edited to give them a Visionary Wonders touch. Phil Isidore was the one who first alerted Mark Meltzer to the existence of these stories. Phil said that in the UFO community there was something called "The Quain question", a debate to the veracity of these stories and of the eventual fate of Quain, who mysteriously disappeared. Mark initially dismissed them as nonsense, but over the course of Something in the Sea came to realize that they were actually rooted in truth.
