From the back of the book:
The world of Overlight is a dangerous place, and the path of the Skyborn is not an easy one. The responsibility of wielding the Chroma is as much of a burden as it is a gift. The ignorant fear the Skyborn, and their enemies are everywhere.
This sourcebook, The Skyborn Order and Its Enemies, provides insight and details on…
Five major conclaves of the Skyborn Order
Having PCs join existing conclaves (or form their own!)
Some of the Skyborn Order’s primary adversaries
Notable Skyborn NPCs that GMs can weave into their stories
In addition to the sourcebook, there is a heavy-duty four-panel GM screen (with art by Kwanchai Moriya), which presents useful charts and information for easy reference during your game sessions.
