Her eyes fluttered open, the pain in her head was gone and she felt much stronger.  Nerissa got up and began to move about the room, trying to find some way to get out.  There was an area in the wall which had sections in it that she could see through.  Putting her hand up, she felt a barrier there, even though it was clear.  She wondered if she could break through and looked around.  She found an object and started bashing away.  There was a shattering noise as pieces of the clear stuff flew in every direction.
