The Moon Winds is not a formal organisation, but rather a faction expressing the general points of views of its members.
The Moon Winds has converted to worship of the Red Moon, usually through the Seven Mothers. They cite the example of the old chieftain Willem the Knowing who showed hospitality to the Lunar Empire missionaries. They seek closer ties to the Empire pointing to the material and cultural benefits coming from embracing the Lunar Way. Bolik Red-Turner and Tarkalus Bigger-Boat lead this faction.
