Aubec of Malador stands before Castle Kaneloon
Castle Kaneloon is a fortress on the World's Edge ruled by the sorceress Lady Myshella of Law. It is from her castle in the farthest south that Myshella encourages mortal heroes (such as Aubec) to journey to the World's Edge and challenge the dangers of the castle. If they are victorious then they are given the opportunity to create new lands from the unformed Chaos around the edges of the World, extending the boundaries of stable reality and thus furthering the cause of Law. When new geography is formed in this manner, the location of the castle is transitioned to the new edge of the Earth.[1]
During the time of Aubec, the castle was situated on a range of cliffs known as the Cliffs of Kaneloon, overlooking a forested plain and a river. A path led up through the cliffs to the castle, while just on the other side of the huge towering edifice the unformed matter of Chaos swirled in an everchanging display of patterns and colours.[1]
The sorcerous nature of Castle Kaneloon is such that intruders within are confronted by powerful illusions, monstrous phantasms created from their minds and imaginations. Those who make the mistake of relying on their weapons rather than their own strength of mind usually perish from fear. Other castle defences are of a more physical nature including guardians in the form of nearly indestructable golems.[1]
When Myshella chooses, the castle may also create more pleasant illusions that reflect the desires of anyone who enters it.[2]
During the time of Elric, the castle was located in the south of Lormyr and was attacked by the sorcerer Theleb K'aarna and the Kelmain Host as part of his plan to conquer Lormyr and the southern Young Kingdoms. He was defeated by Elric with the help of Myshella and Moonglum.[2]
When Elric was sent by Slorg to an alternate world (or timeline) where Chaos held dominion, he encountered a version of Castle Kaneloon that was ruled by the Lords of Chaos, most notably Teshwan.[3]
