"Ashes in the Void" A Warhammer x The Expanse Crossover
21 parts Complete In the Warhammer 40K x The Expanse crossover, When a squad of Salamanders Space Marines is inexplicably transported from the grim darkness of the 41st millennium to the fragile political and human landscape of the Belt, they are faced with a challenge unlike any they have ever encountered. Crystalline anomalies of unknown origin erupt across Ceres Prime and other Belt settlements, their intelligence adaptive, their behavior unpredictable, and their threat to human life absolute.
As tensions rise between Earth, Mars, and the Belters, the Rocinante crew and their unexpected allies-the Astartes-must navigate moral dilemmas, high-stakes stabilization operations, and political interference to save thousands of lives. Every pulse, every adjustment, and every decision is a negotiation with a force far beyond comprehension.
In a crucible of survival, humanity and Space Marines must forge an uneasy alliance to confront the anomalies' intelligence, defend the Belt, and grapple with the ethical consequences of their choices. Ashes in the Void is a story of courage, morality, and the fragile balance between human ingenuity and the incomprehensible forces lurking in the void of space.
