One thing that has completely changed during the last year is the background story. There are two main characters, a man and a woman, who are both students at the headquarters of the Source Hunters. This organization has been created by the council of seven to ban the use of Source, which is used for magic. The reason for this is that even though Source can be used for good, it can also be used for evil. The Source Hunters are responsible for locating the users of Source and stopping them from using it again.
