Barsoom is an ancient and dying world. Endless acres of yellowish moss were once the beds of Barsoom’s five mighty oceans and numerous seas that vanished 500,000 years ago. While there are some natural marshes left, the primary source of water comes from the canal system that relies on the seasonal melting of the polar ice caps to provide irrigation for precious strips of farmland.

Nations and City-States

While some nations can only boast one city, others have a main capital with other minor cities. Helium is referred to as an empire since it controls dozens of cities, including the major metropolises of Hastor and Zodanga. However, the Barsoomian word angtos [aŋ-tōs] more accurately translates to “city alliance”.

Most Barsoomian cities follow an established pattern. Each is strongly walled, with a main gate and several lesser ones. From these gates, streets lead to a central square in the heart of which is located a great temple. The jeddak’s palace, lesser palaces, the embassies and public buildings such as museums and libraries surround the great plaza. Shops and stores occupy certain districts stretching away from the square, while other districts are strictly residential. One street runs completely around the city just inside the walls and it is here that the public inns for tradesmen and travelers are found.

The skylines of Barsoomian cities are marked by towers, domes and minarets. But in recent ages, buildings have been converted to accommodating the flat landing stages of an aerial world, both private and public. Private residences are raised high upon slender metal columns at nighttime as a preventative measure against assassination. They drop gently in the morning.

A black city-state in a great rift valley. It is known for its elaborately carved white walls. The Great Plaza or Aaas [Â-as] is situated in front of the jeddak’s palace. The Kamtolians still follow the Rites of Issus where sins can be washed away by killing captives. This has evolved into an annual gladiatorial game or Dal [Dal]. Additional lesser games or Padal [Pad-dal] are staged for pure entertainment. The games are preceded by pageants featuring a parade of slaves, thoats, trumpeters, banners and pennons. Its jeddak once had access to a psionic device called a nerve index machine, which cataloged every individual’s brain makeup via a lengthy examination to map pain and pleasure stimuli. Doxus would use the machine to torture, paralyze or kill (by stroke) criminals and fugitives. John Carter destroyed the machine, claiming that it would be impossible to fix. Myr-lo, the dead scientist once tasked to maintain the machine, did not design it. The whereabouts of its designer, a female thern morvar named Zallia, are unknown. The military is comprised of 65,000 warriors, with four raiding fleets and two infantry umaks. There are no workers; all manual labor is performed by red men slaves.

The Warhoons wear skulls and dried hands as decorations. The South has 20,000 men (ten thousand warriors) in their horde. The North has over 40,000 men.

Minor Hordes

“In three days we were on the march toward Zodanga, one hundred thousand strong, as Tars Tarkas had been able to enlist the services of three smaller hordes on the promise of the great loot of Zodanga.” PM/24

The larger hordes often recruit “wild allies” to swell their ranks when embarking on military campaigns or hunting expeditions. There are hundreds of these minor hordes, such as the Zarquad [Zâr-kwd] near Toonol, representing around 95% of the population of green men.
