Biography
Igron was a wizard from the world of Asgard. He was in service to the God of Mischief, Loki Laufeyson, and was constantly conspiring in some plot against All-Father Odin. Igron used his resources to dispose of Odin's previous vizier, and have himself appointed as Odin's new advisor. Under Iron's manipulations, Odin became more cruel and relentless in his rulings. Balder the Brave was one of the first to take note of this. One of Igron's spies was Snaykar the Skulker, who kept tabs on any who might threaten Igron's plans.
