"Your greatest enemy is the hero you could have been."
When Voidspawn—cosmic horrors born from erased lives—kill his sister, scholar Kael Veyra awakens a Prime Core, bonding him to infinite alternate selves. To survive, he partners with Aria, a warrior from a dying world, but their pact risks consuming his soul. Hunted by Veyron, a tyrant stealing alternate powers, and haunted by Selene—his sister reborn as a Voidspawn prophet—Kael battles through shattered dimensions to uncover the truth behind the multiverse’s collapse.
But power demands sacrifice: the more alternates Kael merges with, the less human he becomes. Can he save existence without losing himself, or will he become the monster the Voidspawn fear?
