Looking for lost protagonists across the multiverse
You are a protagonist of the world you belong to, minding your business (either trying to graduate, beat an evil mastermind, or just creating the next best masterpiece) when you suddenly find yourself no longer in your world. Making things worse is the fact that no one remembers you, as if you never existed in the first place.
Now you have to travel across the multiverse, setting things right in other worlds before you could set things right in your own world. Do you have what it takes to make it back and set things right?
