Not much is known about Edgar's history. He is a member of the Grey Order. His last mission was "one of destruction," so his current mission is "one of salvation." This current mission is to destroy the Tarrasque. He has offered the protaganists "power to rival that of The Dark One." After starting their quest, they journeyed through a forest, where Edgar was seriously injured after blocking Attona's Quad-Disaster. He was taken away by the Sentinel.
Edgar's only weapon is a rusty longsword worn at his waist. Any other possible weapons he has have not been shown yet.
