Lake Arrius Caverns

Lake Arrius Caverns is a cavern located north of Cheydinhal. This location worked as the headquarters of the Order of the Mythic Dawn in Nirn. The place remained unkown for many years until the Third Age where Bendu Olo with the help of scholars and others Blades managed to uncover its hidden location. Bendu went there and after having successfully fooled them he managed to destroy the Cavern and kill everyone else resided there. After the attack the place was abandoned.
