Fandom: TDK Batman (Nolanverse)
Genre: Horror, one-shot
Warning: Inspired by H. P. Lovecraft's vivid mythos.
Summary: I got to thinking one day about where the name 'Arkham Asylum' had come from. It occurred to me that Arkham is one of the main cities in Lovecraft's mythos. And then I started to think that wouldn't it be neat if the world of Batman and the world of Lovecraft were one and the same? This would certainly explain the unusually vast number of dangerously insane people present in Gotham. This short story delves into the Joker's past and describes the incident responsible for his fall into insanity.
