Warp Wraith. Let the Galaxy Bleed, #1

The Warp Wraith. The galaxy shivers at his name. But fear may be the only way to freedom. After millennia in the shadows, the Vampires now rule the stars openly-and poorly. Whole planets starve; but so long as the Immortals feed, they care little. Dysfunction is tolerated. Defiance is not-and is met with strike fleets and orbital bombardments. Faced with such degradation, people will turn to anyone. Enter the Warp Wraith.
Armed with preternatural speed, skills, and senses, he is almost vampire-like himself. Wherever his masked visage appears, rebellion flares, and self-styled Immortals face the deaths they so long evaded. And with each fresh uprising, a movement builds, uniting the oppressed and the hunted. But what horror hides behind the mask? The rebels in a far corner of the galaxy are about to find out.
