Chapter

A chapter is a part of a campaign, usually comprising a single module. Using chapters allows a campaign's author to break the story into more manageable pieces, and a campaign's players to have a sense of how far through the campaign they have progressed.

BioWare used chapters to encapsulate the parts of the official campaigns that could be played in a non-linear fashion (for the most part, the players can choose which individual quest to attempt next), while the chapters themselves were organized linearly. The official campaigns also feature a special climax for each chapter, and there is a significant change in location when progressing to a new chapter in these campaigns.
