Griffonwatch

Built by Angar Hulmaster, Griffonwatch glowers over the town of Hulburg, a mile from the harbor, perched atop a rocky spur of the eastern ridge. It is the home of the ruling Hulmaster family, the training and barracks of the Shieldsworn, and a place of refuge when the town is in danger of attack. While it is not very well situated to guard the city against attacks by sea, it faces north, inland, a defense against the savage orcs, ogres, and other monsters who dwell in the desolate hills and moorlands of Thar.

History
In 1479 DR, Sergen Hulmaster - a Hulmaster by adoption, rather than blood - summoned a small army of wights and similar undead to the castle, hoping to kill his family and blame their deaths on Aesperus, the King in Copper, so that he could become lord of the town. His plan failed, however, as the Hulmasters all escaped, thanks in large part to Geran Hulmaster, Hamil Alderheart, and Sarth Khul Riizar, who battled first the undead and then the House Veruna guards hired by Sergen to contain them within the castle.
