Gerdok was a Hive Knight, and led the Hive Sect known as the Cursed Brood. Gerdok was vilified even among Hive, due to the Sect's experimentation with Hive magics to create abominations not seen before. They were akin to mad scientists, not unlike Fallen Splicers. Gerdok conducted these mad experiments out of Old Seattle, sometime after the Collapse. While much of his experiments went unseen by Guardians, it was rumored that Gerdok had managed to create Ogres who could explode like Cursed Thrall, detonating like a high-yield bomb. During the Cursed War, Gerdok was eventually slain by Ernaz, who claimed his magic-infused cleaver as a trophy.
