To Get The GF Eden:
Once you have the ragnarok, fly down to the bottom left hand corner of the globe and look for a run down building in the middle of the ocean (it doesn't show up on the map) And land on it by pressing X when your shadow is above it.
Squall will say something about A research center. Go in the door, there is a blue light in the centre of the room.
Every time it stops flashing walk forward and stop when it flashes (otherwise you will have to fight loads of battles-Anacondaur-Bombs and Bloud Souls mainly) when you get to the core it will ask a question, I think you can answer either way and you will fight a ruby dragon.
Kill it and it will ask another Question-one answer puts you outside the other you are back attacked by a ruby dragon. Survive that and it will ask another question.
Scroll to the bottom (where there is no text) and click. You will now be transported inside the core and you will fight the legendary GF Bahamut. Kill him and he will join you.
Now go back outside and visit Edea. Return and there should be a save point next to the hole (if there isn't just mess around some more outside on the world map) Climb across and into the hole.
There is a computer on the wall (near the floor) Examine it and it will open the door on the floor Go down and use 2 RSP on the terminal and go down the stairs.
Examine the computers on the wall and go into the steam room. Go to the back and examine the terminal and collect the 7 RSP then use 1 RSP to get down to the bottom level where you have to use 4 to get down to the ocean deposit.
Go down to the bottom level and you will have to use 10 RSP to continue. Ultima Weapon will then arrive and spoil the party.
He has about 80250 HP and his light pillar attack deals 9999 damage to one person. Draw Eden from him but you must be able to finish the battle coz you can't run.
You can easily boost Eden to 250 and she deals damage in 5 figure numbers. Hint=Rinoa's angel wing attack deals lots of damage.
