Krune was the last immortal Runelord of Sloth who ruled for many years over his city of Orlakan, an integral part of the lost Iskari Empire of Iskandar.

He is believed to have been destroyed, along with the other six Runelords during Skyfall. Krune was a specialist in "Sloth-Magic" (now called Conjuration) and was said to have been a powerful arcane knight.

Like all seven Runelords, Krune had a loyal apprentice; DeKolo. His fate is also unknown.
