An attorney by trade, Clark Peterson doubles as the president of Necromancer Games, perhaps the most prolific adventure publishers in the d20 industry. Necromancer's products boast a "First Edition Feel" that hearkens back to the quality of many of the classic adventures. Clark's professional design credits include Rappan Athuk: The Dungeon of Graves, Crucible of Freya, the Tome of Horrors series, the Wilderlands of High Fantasy, Tomb of Abysthor and the recent City of Brass. Clark has been a judge in the RPG Superstar competition for its first three seasons.
