2 DLCs:
A Vampire army rises from the fortified halls of Castle Thorn, led by the keep’s master, the powerful Lady Thorn. Before this dread host can march on the people of Western Skyrim, you must assault the fortress, fight your way through this monstrous legion, and put a stop to their invasion!

What terrible works has the mad Alchemist Arkasis concocted from within his secret laboratory? The dark creations of the Stone Garden, found deep within the caverns of Blackreach, are like nothing you’ve ever faced before. You and your party must confront the evil genius and his horrifying experiments, lest new monsters rise from the depths!
