Lord Kilburn is an NPC and questgiver appearing only in Might and Magic Book One: The Secret of the Inner Sanctum. During the events of the game, he is living in exile in the mountains south of Sorpigal and Pleasant Valley.
After the completion of Find the Stronghold in Ravens Wood, Lord Ironfist gives the quest to Find Lord Kilburn. Kilburn is within the north of Overland Map Area C3, at coordinates X=6, Y=14. When encountered, Kilburn gives the player a Map of the Desert, enabling them to travel to the Invading Desert in the northeast of VARN-4.
The reasons for Kilburn's exile are not explicitly stated in-game, though, given his title of Lord and the Map of the Desert he provides, he may have once been the ruler of Castle Dragadune.
Given that Lord Ironfist gives the quest to find Kilburn, there may be some connection between the two lords, and he may be related to Lord Kilburn from Enroth, who serves Morglin Ironfist in Heroes of Might and Magic: A Strategic Quest.
- The quest to locate a character named Lord Kilburn was mirrored in Might and Magic VI: The Mandate of Heaven - Wilbur Humphrey instructs the Heroes of Enroth to locate the Lord Kilburn of Enroth, who disappeared after the Night of Shooting Stars. However, in the latter game, Kilburn has been slain before the player locates him.
- The quest was once again mirrored in Might & Magic X: Legacy. This time, Lord Kilburn was located alive, giving players a quest and a quiz.
