im playing ff4 right now thx 4 the spoiler but where do they go i mean in x if 2 summoners summon the same monster who will it come to and there is no way with all the summoning that an aeon hasnt been called by two summoners at once

maybe its like the bartimaeous trilogy where djinni are in a chaotic gaslike form and when summoned forced to take a physical form and if they dont come it hurts them
