about the origin of ultimecia (big big spoiler)

To Squall of Seed:
1-We can´t see Edea´s house on the future.I just see some stange undefined wall that looks like a monster(don´t know what it is up to this day,but it´s not Edea´s house for sure).

That wall is just a barrier that prevents you from entering Edea's house. Its around all the towns, I think (at least I remember seeing it around Balamb, too).

I figure its just to prevent you from entering the towns during compressed time, which the programmers (oh no, logical reasoning!!!!!) probably did, because (a)they didn't want to program the towns during compressed time, maybe due to the fact it would create too many plot-holes, or (b) the towns would be immensly smurfed up due time compression or (c) no more smurfing around with side-quests (hey, maybe Zell would want to get l@id with the library chick in the past, present & future), time to just finish the d@mn game!

Or Retarded Alternate Ending:
Maybe its an explosion at each town and dwelling, that Ultimecia created to destroy all inhabitants of the world.

Or
Maybe its a barrier all the townspeople created to fend off Ultimecia

Or
Maybe Jean-Luc Picard on the USS Enterprise showed up in orbit due to an automatic destress call by the Ragnarok and he's beaming all the towns up to safety

Or
Maybe Osama Bin Laden showed up and fired Nukes at all the towns, so he and Ultimecia can live happily ever after

Or
Maybe its a ruse (like a Ninja's smoke bomb) that all the towns people set, while they dig underground, searching for the lifestream, and the power to defeat Ultimecia

Or
etc
etc
etc......

Something tells me its something along the lines of my first guess
