Before, anyone knew anything, including An herself, the monks were the only ones with a clue. The energy this little one holds, is too much for everyone. It was thought that she was eminating energy so powerful, her baby blue eyes could kill a man with a stare. But later it is found that the "engery" is a whole other entity. A being trying to escape An's little body, not realizing that it needs her to live just as much as she needs it.
