I should think it's obvious. The moment you set foot in this castle, you forgot every spell and ability you knew... though the forgetting does not end there. In this place, to find is to lose and to lose is to find. That is the way of things in Castle Oblivion. Yes... Here you will meet people you know. People you miss. I sampled your memories. And I tell you this go forth and find yourself, and what it is that your 'heart' desires.
