Have you seen me?

Me and some friends came up with an idea for an au for all of us and even though we don't talk anymore the story lives in my brain and I add to it as I go and meet new people.

In this Au there was a nuclear war that decimated the world. The laws of everything have changed. A amnesiac traveler wakes up in a new city not knowing anything and explores the world trying to find themself while meeting mutated hybrids like themself along the way.This world isn't like anything you've ever read, the rules are completely different.
