Fort Dawnguard is a large fort southeast of Riften which serves as the Dawnguard's base of operations.
The fort is home to the ancient order of vampire hunters who guard the realm from the vampiric Volkihar Clan. It is hidden in the east of The Rift, and can be used as a player home. It can only be reached via Dayspring Canyon.
The fort was built sometime in the Second Era by the Jarl of Riften to contain his son, who had contracted vampirism. He hired a large mercenary band called the Dawnguard to guard his son. The threat of vampires was eventually disregarded by the people of Skyrim, and the fort was abandoned. Isran is using the fort as a base of operations for his attempt to rebuild the Dawnguard and combat the rising threat of the vampires.
