Kuvhane is a Sakah Tiefling of Rak Tulkhesh, the Rage of War, and was once a member of the Razor Wind tribe in the Demon Wastes. She has horns and nails of jagged steel, and is particularly gifted at working metals and demonglass, a unique material from the Age of Demons. Kuvhane spent much of her life creating weapons for the Razor Wind, but in the clang and clash of metal shaping metal, and the shaping of demonglass, she found a kind of peace, and that peace allowed her to hear past the influence of her violent progenitor, and to hear the call of Kalok Shash.
She made her way into the labyrinth, where she was found by a patrol led by Svash Ramaal. She now uses her talents in service to Kalok Shash, crafting impossibly sharp and sturdy weapons from demonglass for the Jaasakah Ghaash'kala.
