((I just assumed Milo was on school grounds somewhere, or nearby enough to be affected by the spells.  If your character did leave then assume he arrived when all the spells started going off and that he's been lost in the shadow realms until now.  That's the best I can do since I'm trying to bring this story to a conclusion.  A lot of people have left and I'm running out of ideas to keep people interested enough to keep it going much longer.))
