Page "Corum Jhaelen Irsei" Paragraph 4

Shool then explains that Corum's ill fortune has been caused by the Chaos God Arioch, the Knight of the Swords.

When Arioch and his fellow Chaos Lords conquered the Fifteen Planes, the balance between the forces of Law and Chaos tipped in favor of Chaos, and their minions-such as Glandyth-a-Krae-embarked on a bloody rampage.

Shool sends Corum to Arioch's fortress to steal the Heart of Arioch, which the sorcerer intends to use to attain greater power.

Corum confronts Arioch, and learns Shool is nothing more than a pawn of the Chaos God.

Arioch then ignores Corum, who discovers the location the Heart.

Corum is then attacked by Arioch, but the Hand of Kwll crushes the Heart and banishes the Chaos God forever.

Before fading from existence, Arioch warns Corum that he has now earned the enmity of the Sword Rulers.

Corum returns to the island to rescue Rhalina, and observes Shool has become a powerless moron, and is devoured by his own creations soon afterwards.

Corum learns Arkyn is in fact a Lord of Law, and that this is the first step towards Law regaining control of the Fifteen Planes.
