It seems that Final Fantasy Haeresis XIII by Square Enix has been patented. So far, not much is known about the game since its initial introduction last May 2006. There has been much speculation on what the game will be about, but Square Enix has been quiet about it. They haven't even given information on what console it's coming out for. Still, we scrounged around and were able to get the following information on the game.

So far it is a commonly agreed upon notion that the game will be about certain "crystals". Beyond that is anyone's guess. Another possible clue may come from the Latin word in the title, as the English derivation of the Latin word "Haeresis" is "Heresies". This could mean that perhaps a heresy has been committed against a religion that is dominant in their universe. Perhaps it may have to do with a dominant crystal-worshiping religion which your character going against it? It could happen.

More information will be given at the Square Enix Party on May 12 and 13. A lot of people have been waiting patiently for information about this game, we hope the wait is worth it.
