Heironeous is the champion of rightful combat and chivalrous deeds. Likewise, he is the deity of those who fight for honor and strive for order and justice. Heironeous often leaves the Seven Heavens to move around the Prime Material Plane, aiding heroic causes and championing lawful-good.

Heironeous is tall, with coppery skin, auburn hair, and amber eyes. However, he has the power of illusion which makes him appear as a young boy, mercenary soldier, or an elderly man.

Worshippers of Heironeous are found everywhere but are particularly likely to be found among those who follow military professions or do heroic deeds. Clerics of Heironeous are especially warlike, always wearing chainmail. Their robes are dark blue with silver trim indicating their station. At 11th level, clerics of Heironeous can, in addition to their normal spells, use a bolt of energy once per week. Places of worship of Heironeous are usually adorned with blue trappings, silver, and occasionally windows of colored glass depicting scenes of Heironeous triumphant. A copper statue of the deity, armed with a silver battle axe and covered in silver mail, with seven silver bolts radiating from behind his head, typically stands behind the altar.
