Ice Blade of the Monarch is a two-handed claymore and an artifact created by Archmage Almion Celmo for a failed assassination attempt that has since fell into the hands of a series of malefactors. It is enchanted to inflict Frost Damage, and is currently in the possession of Llaren Terano, a Sorcerer who can be found in the Dunmer stronghold of Rotheran on the island of Sheogorad, south of Dagon Fel.
