Erythnul is the god of envy and slaughter. Erythnul resembles a 7-foot-tall (2.1 m), brutal-looking man. He is rubicund of complexion, hirsute, and muscular, with knotted muscles and a blocky frame. His dull-green eyes are filled with the madness of war. He typically wears red fur and red-dyed leather, and carries a stone-headed mace. A hole in the head of the mace creates a whistling noise as Erythnul swings it; the keening howl of the mace has been known to send those who hear it fleeing until they collapse from exhaustion.
Erythnul is called the Many, because in battle his features continually shift from human to bugbear to troll to ogre to gnoll and back to human again. His spilled blood transforms into similar creatures. Erythnul delights in panic and slaughter. He can spread fear through his eyes.
