Reborn a century after rifts brought monsters and ranks, Calder Rusk wakes in a poor student's body. He awakens as a mocked S-Class Necromancer bound to a battered Gravewright Spade, but his hidden system makes fragility an army: Deathless stacks endless Bone Militia, burying corpses yields experience and cards, so every kill funds more. In the solo trial he saves two cadets Cade traps, breaks Cade's leg and beats A-Class Seraph Brynn Halden to first. He kills and buries Whitcomb's hired assassin. Della Voss gives him her husband Morrow Voss's Marrow Cuff; she doubts his death in a nest collapse, and it doubles his power but drains experience, eroding his humanity. A low-level clearing is an engineered trap seeding high-tier kills into novice zones. To shield his family, he beats Brynn's 300 with one hundred level-20 spore bosses, a record 900. At orientation a widened ruin entrance drags him into the Shard Desert, where he rides Tusk to lure away a harpy flock, his fate unresolved.
