According to some (not very reliable) sources, Vengerberg had been founded by Prince Venger in 8th or 9th century, it became seat of power of Aedirnian monarchs, like famous Baldwin of Aedirn or currently ruling Demavend III. During the Invasion of Dol Angra, Vengerberg had been ransacked and almost all of its inhabitants and garrison were slaughtered by Nilfgaardians. After the war, the city slowly began to regain its position.
