Patron Ascension: I Can Rehabilitate Wraths into My Legendary Spirits

Left for dead before a monstrous Wrath, Rhos is saved by the unimaginable when a primordial entity shares half of its soul with him, transforming him into something that is no longer entirely human. Now able to consume spiritual energy like the Entities themselves, Rhos possesses the authority to reclaim fallen Wraths, restoring their shattered souls and rebirthing them as loyal spirits under his command. Hunted by both monsters and humanity alike, Rhos must grow stronger by consuming the very horrors that destroyed the world. Because somewhere beyond the wilderness lies the truth behind the world's collapse... and he's going to need to ascend beyond every Patron in existence to reach it — Description from novelcodex.org
