Amon-Sul began as Arnor, a young and entusiastic player for the Hammerbolts, the local Norse rivals of the Frost Legion. As his fame grew Arnor retired to take up coaching. Eventually rising to become head coach of the Hammerbolts, he lead the team into the ill fated "blizzard game". Arnor survived all challenges to his leadership, including a battle to the death with the Frost Legion coach. Following his victory (and the delicious meal afterwards), Arnor accepted Loviatar's suggestion of undead transformation. The dark gods, pleased with his actions, brought Arnor back with renewed strength and vigor. In a gesture of respect to the dark gods, the Frost Legion, and his old team, Arnor took to the field again under the name of Amon-Sul (Weathertop in ancient Norse).
