Feros

Mass Effect Solar System Entry
The ExoGeni Corporation has founded a pilot colony on Feros to explore the Prothean ruins that blanket two-thirds of the planet's land mass. The atmosphere is fouled with dust. Terrestrial travel is hampered by crumbled debris dozens of meters deep. There are indications that Feros was a much colder world in the past. Feros has two large moons, Orcan (the farther) and Vardet.

Mass Effect 3 Codex Entry
Feros is a habitable world in the Attican Beta cluster. Two-thirds of the habitable surface is covered with the ruins of a crumbling Prothean megatropolis. In the millennia since the Prothean extinction, the ruins have been picked over by looters many times.

Feros was considered a poor prospect for colonization, as little open ground remains for agriculture. The only sizable fresh water sources are the poles, which are yapped by the decaying Prothean aqueduct systems. The dead cities, while in good condition considering their antiquity, are of uncertain stability. Ground level is congested by a dozen meters of fallen debris, and the air is fouled by dust.

In 2178, the human ExoGeni Corporation announced its intention to place a permanent colony on Feros. The pioneer settlement was placed on the upper levels of several intact skyscrapers, using the surviving Prothean aqueducts and rooftop hydroponic gardens to support the population.
