Commonly known as The Beast of Entropy, the midget in a robe has been seen intermittently sowing the seeds of chaos and destruction.

This NPC has a role associated with it

Lore 10 : He commands the natural forces of entropy and decay;

Lore 20 : He once appeared at the Eladramere Colosseum, and killed the then High Mage Agaros;

Lore 30 : He has been seen around the Forgotten Isle and seems to have a hand in the growing threat of invasion from the Cursed Isle;

Lore 50 : His magics are outside of the agreement forged between the Lady and the Master of the Void, ergo deaths by his hand cannot be reversed;
