Lost Souls (Exalted 2e)

Malfeas is a cutthroat place to live, even for demons. Especially if they lack a patron. You are such a demon and for some alien reason that not even Sacherevell nor Orabilis will explain, you have no idea who your Yozi is... and it creeps the hell out of all of the others. To keep yourselves from getting killed, you and five others have joined forces to survive and find out your own identities and powers. While you are handling war and cutthroat politics, there is some fun to be had. After all, you might have no idea what you are and your limits, but no one said you can't try them out by seeing how far you can chuck a pillow demon across a layer or managing the hellspawn following you.

The game would be set in Malfeas and probably be the demented lovechild of Disgaea and as much of Overlord as someone who has just read about it can put in.
