Elyon
"Just as they expected, everyone above the age of twenty had turned into crystal statues." How did the elves expect all the adults to turn into statues? The Organization planned to have everyone die, not turn into statues, and the only person who knew about modifying the spell seems to have been James (who is no friend to the elves), or Goddess Astrid (who I doubt would give that information to people coming to invade and massacre her kingdom). So how did they find out? The Kraetor Empire might have been able to send notice to their army since Aamon is one of their gods and he helped Astrid, but that still completely leaves out the Elves.
