After living a life of leisure and study, Corum was suddenly thrust into bloodshed and sorrow when he returned from a trip abroad to find that the Mabden chieftain Glandyth a Krae had slaughtered his entire family. Glandyth and his men captured and tortured Corum with the intent to kill him. He escaped by using his natural powers as a Vadhagh, and began a quest for revenge against the Mabden and their creator gods, the Sword Rulers.
Slaying the Sword RulersEdit
The chieftain of the Denledhyssi Mabden who genocided his race, Glandyth-a-Krae, eventually captured and tortured the prince. During his torture, Corum's left hand was amputated and his right eye was put out. As a replacement, he was given the Hand of Kwll and the Eye of Rhynn by the sorcerer Shool. After that, he defeated Arioch and Xiombarg and banished them from the Fifteen Planes.
To defeat the final Sword Ruler, Mabelode, Corum ultimately returned the Hand and the Eye to the Lost Gods in return for their destruction of the Chaos Lords and their minions. While Corum narrowly killed Glandyth-a-Krae in single combat, the Lost Gods completed their task. They also killed the Lords of Law for good measure, forever freeing his and perhaps all universes from their influence. From then on, he took to wearing a metal plate over his empty eye socket like an eye-patch, and a new silver hand he'd made to replace Kwll's.
Slaying the Fhoi MyoreEdit
After the death of his Mabden bride Rhalina, Corum traveled to the far future, and dedicated the remainder of his life to fulfilling his promise to her to protect her descendants, the Tuha-na-Cremm Croich. After fulfilling his vow by helping them slay the Fhoi Myore, seven powerful giants who nearly wiped them out, he returned to his homeland to seek his death. This led to him joining Elric, Dorian Hawkmoon, and Eric Beck on a quest to restore the Cosmic Balance. After Corum returns from his adventures with the other Eternal Champions, his lover Medhbh betrays and mortally wounds him to fulfill a prophecy to purge the world of all godly forces. Ultimately, he was killed with his own Black Sword, Traitor, by his own silver hand.
