If he does not reclaim the book, the Kingdom of Celtland will be cast into darkness forever.

The Japanese Version, released a year later (July 9, 1999), contains several Gameplay (Such as the Defense and Agility stats increasing faster) and story differences (most importantly, a different ending).
