The Khin family had been known to be an Ice user clan but they had to make sure that they can do something that would help them improve their craft and there made have been two craft arts, but people can improve and also make it better and only the head of the family of the Khin could have done that.
But then there were others that had made it to where they will have that power to overcome the great boundary of two crafts and there were soon more powers that were dissolved and rebuilt the system.
There were ten people that climb the Kings Tower and what came with the ten was powers that broke down the ten families and they had to make sure that they can change the Kings Tower around their rules and they had made it to where they will have to cut off people from the outside world, but the reason behind that is still unknown and people are still questioning about how they can leave the Kings Tower.
