The Flying Castle

A powerful wizard lords it over the land in his flying castle, yet he can't resolve the problems that lurk in his own basement!

A flying castle arrives in town. A flight of messenger crows deliver a threat and a demand for a bizarre assemblage of reagents. Will the township try to acquire the goods, or send a party to deal with the castle?

The Githyanki wars are long over, which makes it all the more alarming when an apparently abandoned flying castle drops through a portal from the Astral plane and hovers loomingly over the largest city on the continent.
