Phantasy Star IV Easter Egg - Sega Book Series

On Motavia (the home planet) Go to the town of Krup, where Hahn's family and friends are. Now Go to the last building in the back, on the right hand side of the town, where Hahn's Fiancee is and her day care. Go inside and go over to the book shelves on the right hand side and take a look at the left and right sides of each one. There are four book titles you'll get a kick out of :-)
