Long after the destruction of his world, Harry has gotten used to being the Master and personification of Life and Death, a god or demigod in the eyes of several universes. When he finds a world of summoners he makes a contract with Tom Riddle, a powerful summoner destined to become the greatest dark lord to ever live. Posing as a weak garden demigod, the only one who sees through his lies is Voldemort, the Demigod of War and Chaos, who was summoned by that world's Harry Potter. But what starts as a game soon becomes something more when his new found family is threatened. They don't call him the destroyer of worlds for nothing, after all.
