This generator helps you forge a mighty identity worthy of the Emperor’s lost sons. Enter your Terran name and gene-lineage, then shape your legacy by choosing your homeworld, Astartes Legion, and Imperial allegiance—whether Loyalist, Traitor, or shrouded in mystery. If you bear the full strength and resilience of demigod physiology, select that option to deepen your legend. Click “Forge Primarch” to reveal your personalized Primarch title, lineage, and fate.

Want destiny to decide for you? Choose “Random Primarch” to generate a completely unexpected name and backstory. Each result draws from Legion history, allegiance themes, and mythic traits of the Primarchs—heroes and tyrants alike.

Save your favorite identities to the Imperial archives or transmit them to the High Lords. T
