Questions...(i'll come up with a few.)

im just wondering, how are people from KH and FMA going to be interacting, i understand that its possible to travel from place to place, but there doesnt seem to be a given reason as to how its possible, or how to go about it.

i kinda have a stroy about y it happen on the FMa side

IT is backlash of form sealing the gate of truth and the fact that over time the seal has weaken and now scattered and when it broke it cause a massive cosmic Event that pull the FMA universe toward another ready out of control universe and they collide making three Entrance points for Both sides called crash point in order to pass though you need a portal that will require massive power to maintain for more then a few post but in each of the other universes like if i go to the KH universe them my alchemy is new point less same with your power in the FMA world you still have them and they work but not as well

that and kingdom hearts you know how in the first one it failed and stuff well when we sealed the door to darkness it did more than lock it..... ill righ the actual story later since its not supposed to unfold yet
