![[KostchtchiePic.png]] # Kostchtchie _Demon Lord Prince of Wrath | [[Demogorgon]]'s Coalition | [[Iron Wastes]]_ ## Summary Patron of frost giants who embodies unbridled rage and hatred. Once a hideously deformed mortal human driven to murderous fury by rejection and mockery. Gained immortality through a twisted bargain with [[Baba Yaga]]—who transformed him into the very thing he despised most: a giant. His soul is hidden in nested skulls with a black diamond at the center. From his frozen realm of the Iron Wastes, he's built a following among frost giant tribes who've forsaken their traditional gods for his promise of savage power. Following Graz'zt's defeat and Orcus's destruction, his desperate need for validation drove him to join [[Demogorgon]]'s coalition rather than resist it. %% ## At a Glance 24-foot tall, muscular brute with hunched shoulders and stubby, bowed legs. Malformed, flat face with sickly yellow skin. Hairless except for bushy eyebrows. Tiny white eyes peer from above a massive white beard woven with skulls of defeated kings and champions. Always carries his enormous adamantine warhammer, Matalatok. Speaks in guttural roars and snarls. Prone to explosive outbursts. Voice drips with hatred, especially regarding women. Childlike petulance mixed with terrifying fury. ## Personality Desperately seeks validation while consumed by rage. Pathologically misogynistic. His rage makes him predictable—can be manipulated through hatred of women and need for approval. Desperately wants [[Demogorgon]]'s validation and fears being abandoned again. Creates rageborn demons from storms sweeping through his realm. Has particular hatred for the witch [[Tasha]]. ## Quote _"I am the fury of winter! I am the rage that burns colder than ice! All shall bow before the Prince of Wrath or be crushed beneath my hammer!"_ ## Background Hideously deformed human whose ugliness was matched by his soul's darkness. Rejected and mocked—particularly by women—he was driven to murderous rage. [[Baba Yaga]] granted his wish for immortality but transformed him into a giant. Using her cursed nested skulls, he transferred his soul into a black diamond, making him effectively immortal. The celestial paragon Gwynharwyf eventually struck him down, casting his soul into the Abyss where it took root in the Iron Wastes. He transformed the realm into perpetual winter and rage, corrupting frost giant tribes who abandoned worship of Thrym. When the Great Abyssal Civil War erupted, his need for validation drove him to Demogorgon's side. The Prince of Demons' overwhelming might appealed to his fundamental insecurities. ## Stats **Kostchtchie** (Mordenkainen Presents: Monsters of the Multiverse). %%
