Goodman Games Dungeon Crawl Classics 84.3 Sky Masters of the Purple Planet Adventure Module

When a legendary race of demonic beings pour out of the double-mooned sky and raid the party’s camp, events are set into motion that will lead them far southward to the equatorial region of the Purple Planet. Between them and their destination lay air-ships and aerial combat, pirates and plunder, and the silver-spined Sky-Spire of the Sky Masters of the Purple Planet.
