Evergrowth

Ariel is a mutant abomination and a prisoner of the hellscape that is the Otherworld, an entire dimension built by the gods where the absolute scum of society is thrown away... Or so the people say.

After who knows how many millennia of constant conflict, the neverending fight for survival finally comes to an end as a mad cultist finally breaks the lock keeping the monsters in.

For a world long abandoned by the god-like beings who created the problem in the first place, this is a disaster. For Ariel, it's a buffet.
