Old friend, First Enchanter Casimira was no blood mage! Hogwash! Your story of her investing dark arts into the staff is just that: a fable. Casimira was, in fact, the first leader of Kirkwall's Circle of Magi. She was saddled with the great task of transforming a decrepit, crumbling prison into a proper home for mages transferred to her from all over Thedas. Some of those mages were apostates, men and women one step away from being rendered Tranquil, and it was her unfortunate task to keep order.
