The character then starred in three books making up the "Silver Hand trilogy", and has appeared in other stories taking place in Moorcock's multiverse.

Corum is one of many incarnations of Michael Moorcock's "Eternal Champion", a soul who is reborn frequently throughout the multiverse and usually fights to restore or maintain the Cosmic Balance between Chaos and Law.

In some stories, Corum's adventures allow him to meet other aspects of the Eternal Champion, such as Elric of Melniboné, Erekosë, and Dorian Hawkmoon.

Corum lives during an age before recorded history, when human beings are rising on Earth and beginning to war with the planet's older societies.

The primitive humans of the age mistake these scientific tricks for sorcery and believe the Vadhagh engage in demonic rituals and witchcraft.

Prince Corum is a Vadhagh, one of a race of long-lived beings with limited magical abilities dedicated to peaceful pursuits such as art and poetry.

After having his left hand cut off and right eye put out, Corum escapes by moving into another plane of existence, becoming invisible to the Mabden.

The Brown Man takes Corum to a being called The Giant of Laahr, who treats his wounds and explains he has a higher purpose.

Travelling to Moidel's Castle (a likely incarnation of Mont-Saint-Michel), Corum encounters his future lover, the Margravine Rhalina, a Mabden woman of the civilized land of Lwym an Esh.

Having found out Corum's location by torturing and killing the Brown Man of Laahr, Glandyth-a-Krae marshalled his allies to Moidel's Castle.

Rhalina uses sorcery (a ship summoned from the depths of the ocean and manned by her drowned dead husband and crew) to ward off an attack by Glandyth-a-Krae.

The avatars of the Bear and Dog gods plot with Earl Glandyth-a-Krae to murder Corum and return Arioch to the Fifteen Planes.

Guided by Arkyn, Corum, Rhalina and companion Jhary-a-Conel cross the planes and encounter the King Without A Country, the last of his people who in turn is seeking the City in the Pyramid.

The group locate the City, which is in fact a floating arsenal powered by advanced technology and inhabited by a people originally from Corum's world and his distant kin.

Kwll later appears to Corum and reveals that all the gods - of both Chaos and Law - have been slain in order to free humanity and allow it to shape its own destiny.

The previous trilogy hinted at a Celtic or proto-Celtic setting for the stories - the terms mabden (human beings) and shefanhow (demons) occurring in these books are both Cornish language words.

The Fhoi Myore, seven powerful but diseased and barely sentient giants, with the aid of their allies have conquered the land and plunged it into eternal winter.

Corum seeks the lost artifacts of the Tuha-na-Cremm Croich - a sacred Bull, a spear, an oak, a ram, a sword and a stallion - which will restore the land.

They battle the Fhoi Myore, who themselves have allies: a returned Prince Gaynor, the wizard Calatin and his clone of Corum, the Brothers of the Pine, the undead Ghoolegh and a host of giant demonic dogs.

After being instrumental in the death of two of the Fhoi Myore and restoring to his senses the encircled Amergin, the High King and Chief Druid of the Tuha-na-Cremm Croich, Corum and his allies fight a final battle in which all their foes are destroyed.

Corum decides not to return his own world, and is attacked by his clone, whom he defeats with the aid of a spell placed on his silver hand by Medhbh.
