In his world, nature is kept in balance by giant crystals called El that are attuned to the six elements and tended to by trained priestesses. If an El if damaged, misused or otherwise disturbed, it can result in catastrophic natural disasters. One such event was so severe it caused the original El to be split into fragments and scattered across the world, along with splitting the continent itself in two and nearly destroying all civilization in the process.

More importantly, as far as Add can tell so far there is no El present in this world at all, so obviously that means there's nothing to keep the environment in check and it's frankly a miracle anyone is even alive right now. The random windstorms are even more proof, see??
