Inside Haddock’s Market dungeon in southeastern Craglorn. Southeast of Ogondar’s Winery, east of Belkarth.
Start in Belkarth and follow the road going east. After you pass Ogondar’s Windery, get off the road and head south until you reach the dungeon’s entrance. Skyshard is near the northernmost tower, left of the stairs leading into the tower, in front of a statue, next to a tree. The last boss, Ariana At-Fara and her pets, are in front of the tower.
