From publisher blurb: There is no greater freedom than the skies! The Cartographer's Society is one of the most ancient organizations in Aden, and one of the few that have survived. For centuries, they have explored the farthest, most remote reaches of the Known Lands, and the key to their success has been the use of airships. But they are not alone in their work! The Thunder Scouts, rugged warriors beloved by all for their fearlessness, continue to carve new paths through a strange and threatening wilderness. Wherever frontiers exist in the world of Aden, there are explorers from these two organizations pushing them ever back. The Cartographer Society's Guide to Airships introduces new rules for creating, personalizing, and operating airships of all different shapes and sizes, while also providing essential background on their history and the history of the Society itself. It also delves into the story of the brave Thunder Scouts and how they came to be regarded as folk heroes throughout the Known Lands, along with new chasses and upgrades available to characters who choose to play a Thunder Scout. In Aden, even the skies are deadly!
