He is a powerful demon that is meant to be the leader of Diablo's army.
I will add Run Azar is a leader of a proper description soonfearsome demon army called Nightmares. The Nightmare demons use elemental forces like Fire, Ice, Lightning and Poison. Actually each demon possesses one of the element powers. There are Fire Nightmares and Poison Nightmares that are often met, and Ice and Lightning Nightmares that are rare. The story tells that Run Azar and his army served Diablo since he first walked the earth. The army of Nightmares leaded by Run Azar fought Tyrael, but today I have no timethe clever archangel lured them into a trap and used powerful holy force to imprison them. This was a great loss for Diablo himself. I will add concept art as soon as I draw it When the fiery harbinger of doom /the meteor/ fell on the ground its powerful magic destroyed the prison of the Nightmares and Run Azar, and they were finally free.Stay in touch Will add a picture after some time.
