Sorcress powers have to be passed on. Edea's were passed onto Rinoa, Rinoas were carried across generations to Ultemchia and then Ultemchia's reached Edea again. Im not 100% sure but i think Adel got hers from someone else like in the tutorial it has info on the 1st ever sorcerer. But when Squall and co killed Adel were her powers passed on?Or did they jusr freeze her back and chuck her back into space?
