Sky Masters of the Purple Planet

From publisher blurb: A Level 6 Adventure on The Purple Planet for DCC RPG When a legendary race of demonic beings pours out of the double-mooned sky and raids the party’s camp, events are set into motion that will lead them far southward to the equatorial region of the Purple Planet. Between the party and their destination lie air-ships and aerial combat, pirates and plunder, and the silver-spined Sky-Spire of the Sky Masters of the Purple Planet!
