I have what may be an important question. Is it absolutely necessary to craft and prepare a spell before it can be cast? Would it be at all possible for somebody to cast a sort of impromptu spell?

Hm.  Magic is defined by its Forms and its Affinities prescribed during spell preparation.  Also during the preparation, it is given a name/incantation which is used to cast it.  If a person lashes out with magical energy, with no definition and an incantation made up on the spot, I suppose a primitive spell could be used.  It would be a lot like raw magic, very dangerous and uncontrollable, most of all to the user.  I've been thinking of making a little tab for certain supernatural diseases/afflictions present in Protea, and this would help thicken that list.  I shall call it Burnout - decreased ability to regain mana and use magic after using a spell that hasn't been prepared.
