The Elder Scrolls 3: Bloodmoon

Bloodmoon is the second expansion pack for Morrowind, set on the icy island of Solstheim, northwest of Vvardenfell. As the East Empire Company struggle to establish a new colony on the frozen shores, mysterious occurrences and the arrival of werewolves begin to transform the land. The native Skaal tribe herald the changes as omens of the Bloodmoon Prophecy, and the start of the dreaded Hunt of Hircine. As the Nerevarine is unwittingly drawn into the hunt, there is only one choice to be made: to become the predator, or the prey.
