They're... I don't even know. Crazy should sum it up. I can tell you that Kingsley and Moody aren't behind you being here, though. Basically these seals over hell broke and brought people here from all over, different dimensions and all. So you're now in the year 2011 in Lawrence, Kansas.
As for why you were brought here, big battle between good and evil, heaven and hell, angels and demons, that sort of thing.
Hogwarts doesn't exist, neither does the Ministry. Or. They do, but in books written by a muggle woman. Bloody strange.
