A hapless human is chosen as living sacrifice to seal away the Mistress of Shackles, a sorceress whose power feeds on male submission. Guided by three beast-women—Zharra the gnoll, Syrina the harpy, and Seraphina the centaur—he is trained in body and spirit: humbled by Zharra’s penetrating dominance, bound in worship at Syrina’s cloaca, and tempered through Seraphina’s merciless ball grip. By journey’s end he is no longer merely a man, but an offering, remade to suffer eternally as the sorceress’s vessel, his fate a grim salvation for all others.
