I believe that Lucas (who was and still is the magician of he tower) told that fucking "uncle" he was worthless (as he should) and that Lucas couldn't sense any mana from him. this was when the previous king (Claude's father) took anastacius to the tower for evaluation or to request lessons or something.
I know we got a small glimpse, but I wonder what really happened between Lucas and Anastacius.
