Heironeous appears as a tall human man in a full robe of chainmail so fine that it moves with him like cloth. He has auburn hair and skin the color of copper, and is impervious to all but the mightiest weapons. His signature weapon is a great magical battleaxe, though he has recently taken to the longsword.

Half-brother and sworn enemy of Hextor, Heironeous is the son of Stern Alia, the goddess of Oeridan Culture, Motherhood, and Law. Heironeous considers gods who stand against evil to be his allies, while those ascendants to promote suffering and evil he deems foes.

Heironeous is the patron of House War.
