Kr'y'izoth

Kr'y'izoth are one of two species of undead githyanki which can be found in the realms of Dungeons & Dragons. Specifically, they are one of the two unique githyanki undead created by Vlaakith CLVII through the powers of the Crown of Corruption, with the other being the Tl'a'ikith.

Created from githyanki wizards, sorcerers and warlocks, kr'y'izoths appear as emaciated and charred githyanki shrouded by an aura of flickering, shadowy-black flames of necrotic energy. These flames obscure their features; even those who knew the creature in life are often hard-pressed to recognize them in death. They speak in a hollow, clipped tone of voice.

Ironically, they're described as far more social and versatile than tl'a'ikiths are, which means the lich-queen uses them as high-level troubleshooters. With their aditional ability to magically heal others, this means that kr'y'izoths are often attached to elite githyanki units, and so can be found across the Astral and on other planes as well as guarding Vlaakith's palace on Tu'narath.
