MoonEater

Demonic shapeshifter named MoonEater was on the loose one thousand years ago, terrorizing villages and people.
He was captured by the demon Revenge, from an angry person whose parents were killed by MoonEater.
MoonEater was trapped in a box under the earth so he couldn't escape.
Eventually, a thousand years from then, someone worthy was destined to summon him from his muddy grave and set him free.
Once free, he may set Chaos and Destruction free to do his bidding and destroy the world for keeping him prisoner once and for all.....

And it's all up to the Chosen One to stop him.
