Pierce walked into the last room.  She ran her hands over the books reading the titles.  So much knowledge in this room.  All of a sudden she heard it open and swung around.  She was suprised at the beings angelic appearance.  While she wanted to ask she realized she was in trouble.  Not thinking she shouted out the words of a spell.  She threw her hand forward as the spell sent out a wave of invisible force meant to knock the priestess back and away from the only exit.
