Evil in Waiting

Upon entering Voltune the player encounters a spirit NPC named Valdar. The player is instructed to collect 3 vessels in the cave and bring them back to Valdar.

Upon returning to Valdar he will tell you that by pouring out the contents of the vessels, the lich entombed in the caves will be deprived from regaining its full power. After the player pours the vessel contents into a fount and sits in the throne, Valdar will reanimate the lich, who will still be formidible (according to Valdar).

Valdar then awakens Hevnoraak (a Dragon Priest). Like the other Dragon Priests, Hevnoraak casts powerful lightning spells at the player and summons storm atronachs.

When defeated Hevnoraak will drop the dragon mask Hevnoraak (armor:25, weight:9, value:891) which makes its wearer immune to both disease and poisons.
