Reborn through the Blood God System, an ancient imprisoned entity sealed inside the Kalu bloodline for six generations, Draven discovers that every enemy he absorbs makes him permanently stronger. But the system is not his. Shikakiro, an ageless architect who has been dismantling bloodlines for thirty years, has partial access to everything Draven feeds it through a hidden sigil placed without his knowledge. As Draven fights to grow faster than Shikakiro can harvest, manage a Corruption threshold that risks silencing his dead clan’s voices forever, and navigate a city that has been publicly storied against him, he returns to Voldimore with one question that matters more to him than revenge.
