Promachos, the lost primarch.

In the far future of the 42nd Millennium there is only war. Countless souls are lost upon the stars, never to be discovered by traveling ships, and warbands. The galaxy is ruled by two halves, the corpse of an Emperor, and the 4 gods of chaos. Abandoned by her father, Promachos fights Chaos alone, as she and her people have for millennia. Flung from home by chaos, as her brothers were. She was left to forge her own path. And so she has. Ruthless and cunning, using nature and the environment to her advantage, she has held the line. Protecting her home planet of Ellas from Chaos. With Guilliman and Bellsarius Cawl making advancements, now is the time for Promachos to be united with her family.
