The Aether Engine

A Living World That Remembers

With the rise of AI many gamers, writers, bookworms, and others like them are interested in roleplaying with new AI tools. I found myself among that collection and was constantly frustrated with the little details the AI would hallucinate and forget almost CONSTANTLY so I took it upon myself, and after an embarrassing length of time and many many iterations, I created The Aether Engine.
