1 - What was the whole story behind that 'Old Key'?
2 - What was the giant crevasse about near Trabia (where Nida said the the dial in the Balamb Garden was going crazy when it got near or go over it),
3 - The out of place blue spots on somewhere on the Centra Plains (i never understood why there were there, but at the same time why would anyone put them there if it was for no use).
