 Dragonlance is a story, in contrast to many other "Dungeons & Dragons" adventures, particularly those that came before it, which are location or event based.The module series is built around the structure of three "books" that are split up similarly, but not the same, as the Dragonlance Chronicles novel trilogy.Each "book" runs through four modules and contains sections of the adventure called chapters which have a continuing numbering system through that individual "book".
