bookcase

I am supposed to put the charged crystal on the bookcase in the libary, but it did not appear when it was supposed to, Now I am stuck and can.t go any further. I tried putting map on globe but it keeps telling me I need corodinates what am I missing here. Please help Thank you

You need to get a magic quill that will write the coordinates in the book and then put the map on the globe. The quill is in 3 peices (i think its in the attic room accessable from the coutyard) good luck!
