Luna didn't expect to emerge in another world and be chosen as the leader of 11 teenagers with extremely powerful powers.  There is a phrase in the Bible that says _many are called, but few are chosen.” _ Jesus said that.  It happened that when you are called, if you accept, you are chosen.  Maybe it doesn't make that much sense, but if you think about it, only those who accept your calling are chosen as guests, invited to do something bigger.  guests, trying to be a part.  And the Kingdom of El-lar is huge enough that there's trouble around every corner, so really, Luna can't just deny that calling, as much as she loves taking a nap, there are far more important things for her to deal with.
