Omg Tiffie Trust you to come in and work out the answer in an hour. I just checked back and this riddle has been going for over a year! A year! :laugh:

Yeah, the answer is the Card Collector's series. Volume 7, 8 and 9 can be found in Card Freak Gon's bookshelf each at a different point in the game. You got the reasoning pretty much all down; the last line is the last piece of the "directions" to the answer: You start at the Hunter's Gate, and head forth four times. "Still far from the north" refers to the fact that what's here referred to as "forth" is often called north in descriptions and such, so you'd be walking to "the north" but, being in Lindblum, you'd still be in the southernmost part of the world.

Hehe Quin will be pissed! Or maybe relieved. :P Make us a nice riddle, anyway, Tiff!
