The Elemental sisters were done for a contest of a Final Fantasy club in deviantart, and I won!! ^__^ So this is a bit of the stories I wrote for them: 'The elemental sisters are not a common aeon. You can choose one of them when summoning, either fire or ice, they don´t appear togheter. But the sisters are cursed to an ethernal war against each other, since they represent opposite elements; so when they meet, desaster is close. The special attack of the sisters (limit attack, or as you wish to call it) consists in summoning one sister while the other is on the battlefield. When they see each other, they prepare for the battle of their lifes, and use their moist destructive attacks trying to destroy the other... all this of course, catching the monsters in the middle of their neverending fight.'
