Frazzn'korth, originally known as Nidhogg the Black, was a fearsome dark dragon who used to terrorize the world and openly defied the rule of Dragon Patriarch Khellendros the Blue until he was sealed away into the Dragon Diamond by the sages of Dar'Cenrath who sacrificed themselves to accomplish it. He lay dormant in the diamond for millennia until he became the object sought after by Malakhia d'Zarnagon and later Kareth d'Zarnagon who wished to release him to gain his power. At the end of the Great War, Kareth succeeded in freeing both the dragon and Malakhia's spirits from the diamond and merged with them, which led to the creation of the Godslayer who caused the Cataclysm.
