Personally, I wouldn't want levels to be named directly after "Angels". To me, for some reason, this place has a mix of Buddhist and Christian overtones by various level names, and sections of the Monestary. I hope this was an intent, and I am not the only one who sees it :) But, if you start higher levels by being names of "Angels", you really make it a Perl Monestary whose highest members are Christian Angels. I would rather have added level names not be religion specific. I'm just funny about that kind of thing :)
Actually, this brings up another idea. Maybe we could choose our level path. Level systems (all sharing the same XP systems) could be made for other religions, or themes (Buddhist, Catholic, ..insert religion here.., Medieval, D&D, whatever).
