End Realm

A man finds himself in a dark unfamiliar world of starlit rivers and black obsidian landscapes, with only two golden coins as his possessions and no memory of who he is or where he comes from. He soon learns he is in a place called the End Realm from the monstrous boatman on the River Styx, who delivers him to his final destination: the Lowest, the worst prison in Tartarus. But his damnation to the Lowest doesn't make sense, and most entities agree that he is not meant to be in the realm at all.

With the mysterious appearance of a ring on his left hand, he takes this as a hint at his past . . . and a spouse he doesn't remember. This possibility spurs him to traverse the treacherous afterlife-a place where heaven and hell are one and angels and demons both hold great power-in search of a way out so he can do what he wants more than anything: get back to his wife still breathing in the living world, even if that means seeking help from the Devil-God himself.
