Sorry for the delay guys, crazy weekend.

You take the books out and line them up. At first you cannot make sense of the writings on the front, but it doesn't take long for you to at least recognize what you need to do. You take the Gem out of your bag and, taking off your current headpiece, set the Gem around your head. It seems to take on life of its own, floating around your head. However, once you do and look down at the writing again it all becomes clear.

They seem to be ancient texts, in three volumes, relating to Asmodeus. All three have his symbol on them. They are older than any other book that you have ever seen, and seem like they would probably fall apart if handled too much. They seem to be fine at the moment, but need to be preserved, in Mai's opinion, soon. Otherwise the information in the might be lost for forever.
