The story is there are two clans one is "Midnight" the other is "Moonlight".
At one time these clans use to be allies but something went wrong and now they are against each other. Each clan has there own version of the story and it is told differently each time. The real story is that One brother was an alpha the other wanted to be alpha as well. The brother got jealous and tried to get rid of the other brother but that backfired and so the brother went and he took with him some of the clan that wanted him to be the alpha.
It is twenty years later and there are two new alpha's for the groups. The story has long since been mixed up but the clans are still against each other.
