Krune was the last Runelord of Sloth. He once ruled Ezdar; one of seven Imperial Districts in the lost Iskari Empire.

Krune was a specialist in "Sloth-Magic," which is now called Conjuration, and was said to have been a powerful arcane knight.

For many years, Krune ruled from the district capital of Orlakan, which was located deep within the Desert of Desolation of Ikharos.

He is believed to have been destroyed during Skyfall, along with the other six Runelords.

Krune had a loyal apprentice; DeKolo, whose fate is also unknown.
