The Circle Tower, officially named Kinloch Hold, is Ferelden's regional headquarters for the Circle of Magi. It is located on Lake Calenhad, and accessed only by its docks. As per Chantry and local law, human and city elf citizens of Ferelden with magical potential are brought here to be imprisoned for most of their lives and instructed in the legally-approved Schools of Magic, and (ideally) trained to resist demons (who seek especially to possess living mages).
