A religious cult has built a temple and surrounding dwellings on this island, and they float across the continent indoctrinating and spiriting away new followers. Of course the more established religions on land encourage all to resist the new cult and attacks on the island are common. It floats and steers very slowly with the use of huge lode stones. Peasants on the ground are taught by the churches to set forest fires in the islands path to suffocate the inhabitants.
