Flags over Mars
The default time period for this adventure is shortly after the bulk of the events of "A Princess of Mars" and the decline of Helium’s long time rival, Zodanga.
As the adventure starts, Carter is traveling 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 and John Carter. 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.
Strange machinations are afoot and you never know what really lurks down there in the hidden places.
