maybe I read over this somewhere, but I have no answer...
the question is: how many aspects (semi-permanent) can a character have? or is there a limit to the number of aspects a character can have?
here we have our apprentice wizard with his high concept aspect and his 5 phase aspects. as I understand it these are pretty permanent, but can be changed according to events. maybe he becomes a warden and changes wizard apprentice to puppy warden. same goes for the phase aspects. we can also say that he has always at least 6 aspects.
during a session he may gain some temporaries like consequences or via maneuvers or debts to sponsors and the like.
let's say during an adventure he befriends tom, the troll - this may give him the aspect my friend, the troll. and since that would not be a change of the high concept or an phase aspect, it must be a new one, and as long he or the troll doesn't break the friendship it is pretty permanent. right?
