Zuthan was the last immortal Runelord of Gluttony who ruled for many years over his city of Ghatash, 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. Zuthan was a specialist in "Gluttony-Magic" (now called Necromancy) and was said to have been a powerful arcane knight.

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