Hellmarine 4: One Shall Crumble

The cycle was never meant to be broken...until now. Deep in the shattered remnants of a dead moon, an ancient artifact pulses with Supernal Energy—power from before the Multiverse itself. The Hellmarine and his battle-scarred Stygians have stumbled onto a secret that Heaven would kill to possess and Hell would burn worlds to claim. But in the space between spaces, where nightmares older than demons writhe in eternal hunger, the Archduke himself delivers a terrible warning: Whoever slays the beast becomes the beast. Now, with the Heavenly Host descending like vultures and reality itself bending under the weight of forbidden power, the Hellmarine must navigate a conspiracy that spans from the lowest pits of Hell to the highest thrones of Heaven. Alongside him stand those who refuse to let him fall: a genius xenobiologist who anchors his humanity, a Ghost AI who defies her own limitations, an exiled angel questioning everything she once believed, and a squad of Marines too stubborn to die. He is the Hellmarine, and he will not kneel to fate.
