From the publisher: This 128-page book by Ari Marmell presents a dozen different planar factions ready for use in planar campaigns. Each Planar Faction includes the organization’s overall makeup, its resources and base of operations, its history, its goals and methods, its internal laws and customs, and new game mechanics specific to that organization. And because each faction operates on multiple worlds, you can make them a driving force in your own setting, or use them as a means of introducing your PCs to planar adventuring.
