Merciless Saviors - H. E. Edgmon

Gem and the other gods wake to find themselves returned to the Ether, in the bodies they had a thousand years prior. Now in a world deeply corrupted by a millennia of the Shade's rule, they must all find how they fit into this new chaos. Alliances break and form as Gem and the others travel across their old kingdoms, having to decide the fate of not just this world, but all worlds.
