Grimnr, a Frost Giant, was the leader of the Frost army. He, similar to Captain Bloodhammer, got his power from one of the three Gleipnir shards, which he obtained from Vili's tomb at the Hall of Valheim. With this power, he planned to win the Battle for Nordr against the Nordrmen. His attempt at a resurgence failed, as he was defeated by the Heroes of Legend, who took the Gleipnir shard.
