JAGS Treasure

From the introduction: Treasure...makes a certain kind of adventuring interesting and fun. JAGS Treasure is meant to serve several purposes. First, it's a cool list of magic items that you can use in any campaign. Second, it provides a history of sorts - it's not exactly a world book, but there is a time-line and some ideas about where all of these wonderful toys might have come from. Finally, it describes a "popcorn fantasy economy".
