Located on a strategic hilltop in the middle of the Angle, Thuin Boid (Du. "Hill of the Dwelling" Rh."Thiudabaurg", "People#s Fortress") overlooked the Men Egladil, the road connecting Fennas Drunin with the Menatar Romen. The minor fortress had been taken, retaken, and rebuilt many times. In Stonearm's War, it was seized by King Ermegil of Rhudaur in T.A. 1634 and re-captured by Baumyakund of Feotar in T.A. 1638. It was later held by a mercenary company in the pay of Feotar led by commander Aldúrin, a Tarkil from Cardolan, who was cousin to the mercenary Captain Daeros of the Cruaidh Maraich. Later Thuin Boid became the capital of the Vulseggi.
