The Prophecy of the Grand Amplifier is a setting-spanning, sourcebook and campaign written for the Upwind roleplaying game. The book is packed with new locations, NPCs, Relics, creatures and Master's caches, and the adventure will draw players deep into the setting.

The story takes a band of young Knights from novice recruitment through their Academy training, challenges them with their graduation cruise, leads them on a ranging series of missions across the Realms and then sends them deep into the Dark in pursuit of an ancient legacy.

The discoveries they make along the way will upend everything they know about the history of the Children, the Masters of the Wind and the origin of the Kin themselves.
