Mercy's Eclipse: "The White Witch of Tactria"

Haunted by the aftermath of the Necro Wars, Hitomyris survives as a necromancer-for-hire, searching for any sign that her family might still be alive. Her search leads her into the Stygian Reach—a remote expanse of the universe home to some of the most dangerous galaxies in the cosmos. But as old empires rise once more, ancient hatreds resurface, and a war over the future of the galaxy begins to take shape, the last place she wants to be is at the center of it.
