It is not known where Yellow Ash came from, or how he became so devoted to the Lord of the Wastes. Based on his appearance he was most likely born in Thrane, but his mind has been warped by the dark religion of the sand elves.
Yellow Ash is one of the more fanatical servants of the Desolate One. He has pale skin, clouded eyes and long, stinking black hair. He seems driven to torture and humiliate innocents (particularly children), taking his name from his habit of burning his victims and urinating on their remains.
