Yngol Barrow

Yngol Barrows is an ice filled tomb located North-East of Windhelm bordering the river. It contains Draugr corpses and adept level chests. This area also requires the Coral Dragon Claw purchased from Birna (shopkeeper in Winterhold for 50 gold). The final room contains Yngol's Shade, an undead wielding an enchanted battleaxe and uses frost spells. Upon defeating Ygnol the exit can be unlocked by removing the Helm of Yngol from the skeleton seated in the chair.
