The moon has been kidnapped, and is currently being held hostage. Within the world of Infinite Undiscovery, a sinister group known as the Order of the Chains has ensnared the moon, locking it in its place in the heavens with heavy... well, chains. Didn't see that coming, did you?
The group is lead by their enigmatic leader, the Dreadknight – a name which may ring a bell for serious Square fans, since a similar character appeared in the second Final Fantasy game. His human name (as opposed to his title) is Leonid. Now, Final Fantasy fans may not have heard that variation of the name before, but it's definitely something they have come across in the past.
