The multiverse is slowly being corrupted. Many universes have already fallen into decay. As their worlds crumble the World Lords, ancient beings of immense power, call out to their long-forgotten creator, asking for aid. Their requests are answered, however the form that aid takes is rather, unexpected.
They are not given more power or direct intervention. Instead, they get a few handfuls of weak unsuspecting souls in need of endless training, as soldiers. If that wasn't bad enough. An entity that was ancient before their universe was born, is assigned to keep an eye on the help. The entity in question isn't exactly happy about it either.
None of the parties involved are happy with the situation, but they will have to learn to work together if they want to survive what is coming.
