Dorsa Brevia was a hidden settlement near the South pole of Mars and one of the most important cities of the Martian underground.

Dorsa Brevia was one of the natural cavities formed by ancient lava flows, which created channels that snaked through the terrain; the outer layer solidified and liquid lava flowed inside, leaving behind large and long empty tunnels. The dorsa ran in the North-South direction.

Deimos was one of the two natural satellites of Mars, the other being Phobos. Its name means "dread" in Greek.

In the preparations for the Second Martian Revolution, it was feared that it would be used as a weapons platform. A team led by Sax Russell and Peter Clayborne landed on it and placed automated diggers and attitude jets. The diggers expelled matter and thrust it away from Deimos. Due to mass loss, Deimos's orbit expanded until it left Mars's attraction entirely.

Underhill was the first Martian city, built by the First Hundred upon their arrival.

The site was chosen prior to their arrival; equipment was sent on the site with three unmanned expeditions prior to the arrival of the Ares. The settlement got its name because of its underground location beneath a hill.

Zygote (and later Gamete) was the secret underground city that was the home of Hiroko Ai's group and a major city of the Martian underground.

City planning
Zygote was situated very near the south pole of Mars, inside a large natural cavity under the dry ice (solid carbon dioxide) of the polar cap. The dry ice was sprayed with water, which froze and formed a solid dome under which the settlement was protected and airtight.

Da Vinci began as a refuge for the terraforming team of Sax Russell in the years following his capture and leading up to the Second Martian Revolution, afterwards becoming an elite scientific co-op laboratory on the shore of Chryse Gulf.

Prelude to the Second Revolution

Burroughs was an important Martian city situated in a low point near Xanthe and Isidis Planitia.

Among the first Martian settlements to be founded, this tented city expanded very quickly until it became the biggest city on Mars and the planet's commercial and administrative capital. In 2057, it was the place where the negotiations for the renewal of the UN Mars Treaty took place. Burroughs lost its dominant position in Martian affairs after the space elevator opened in Sheffield, however it remained a very powerful city thereafter.

Simon Frazier was an English geologist, member of the First Hundred. He was one of the most important areologists of the early years and with Ann Clayborne they conducted some of the seminal work in their field.
