Here, amidst wonders and nightmares, he discovers a terrifying truth — every time he dies, he comes back stronger. The Abyss isn't a prison, it's an all-you-can-eat buffet of XP.

Godclads

OstensibleMammal

In the corpse-city of New Vultun, humanity slaughtered the gods and built a civilization from their remains — Frame, Heavens, and Souls power chrome, fire, and reality-bending miracles. Avo was created as a mindless dog-warrior for a doomed war, too weak to survive in a world of enforcers, chromers and golems. Taken in by his adoptive father, he defies his violent nature and masters Necrojacking — hacking minds and ghosts. When he awakens in the gutters with an immortal Soul burned into his being, he must graft greater gods to his Frame to survive, hunted by the Syndicate and the half-strands of dead divinity. Cyberpunk, eldritch and brutally physical, Godclads follows Avo's apotheosis from prey to predator as he claims the mantle of divinity and asks what kind of god he will become. A best-rated Royal Road serial with millions of views, now professionally edited for Kindle.
