About the adventure

This heroic pulp adventure is from the John Carter of Mars Quickstart. It is set shortly after the events of A Princess of Mars and the decline of Helium’s long time rival, Zodanga. As the adventure begins, Carter is travelling with Dejah and several friends and allies by flier to meet with a delegation from a minor Red Martian kingdom, Voninka, that is seeking alliance with Helium. Voninka was a small satellite nation of Zodanga until the nation’s recent defeat at the hands of Helium. It now seeks new allies among Helium and its jeddak, a young but respected leader known as Corlan Nim, has requested a diplomatic meeting with representatives of Helium—the player heroes and their crew. But all is not quite as it seems and this apparently simple diplomatic mission soon launches our heroes into a whirlwind adventure!
