Ratz

Intro Ratz is a 20 year old female, who had an accident fell into a manhole into a sewer hitting her head and removing her ability to talk, (idk how that works only backstory that came to mind.) Through the power of cliches and storytelling she gains the ability to somehow only communicate to rats and use them to do good deeds, you're whoever you want to be, this is just some random crazy rat girl.
