Lenvan (also known as Lich-Lord Lenvan) was one of the Wesfolk leaders who became a Lich-Lord. He obtained the Ruby of Fire, but during the first Wesfolk War was trapped underground for years until being killed by Prince Haldric.
|Free! I'm free at last! No mere magi could seal me in here forever! Rise, my soldiers of darkness, the world will be ours once more!|

Before transforming into a lich, Lenvan was one of the great Wesfolk leaders. He, among others of the Wesfolk, pursued the art of necromancy as a means to live forever. He helped the Wesfolk escape from the Old Continent to the Green Isle, but becoming undead made him fall into darkness, developing ambitions for world domination.  He obtained the Ruby of Fire, a valuable artifact brought from the Old Continent, from his arch-rival, the Lich-Lord Caror. During the first Wesfolk War with the people of the Green Isle, one of the kings there managed to trap Lenvan with the Ruby of Fire inside the catacombs beneath an Oldwood Forest temple, magically sealing it to prevent his escape.
Over time, the woses of the Oldwood Forest learned how to break the seal which trapped him inside. Their leader, Elilmaldur-Rithrandil offered to open the catacombs to allow Prince Haldric to enter and retrieve the Ruby of Fire. Lenvan fought against Haldric, and raised the dead against him, but was eventually slain, while the Ruby of Fire was found and brought back to the surface.
