Phobos

Phobos (pronounced /fow-bows/ ) is the larger of Mars' two moons, and an ecumenopolis. Roughly twelve kilometres in diametre at the widest point, Phobos serves as a transitory hub for cargo and passengers making their way too and from Mars. Two dockyards run along the moon, perpendicular to each other, serviced by numerous magTrams.

Geography
Most of Phobos is taken up by the Hive, an enormous jigsaw of spiked towers and industry, formed by six centuries worth of raw economics without the confines of gravity. The outermost layer of the Hive, known as the Needles, is home to many wealthy individuals, largely Golds and Silvers. By contrast, the Hollows, in the middle of the moon's hollowed-out interior, is a den of poverty.

Features
Most business on Phobos is related to one of two corporations: Julii Industries, owned by House Julii; and Sun Industries, owned by Silvertongue. A distinctive feature of Phobos is the Sun Towers, a double-helix skyscraper housing the headquarters of Sun industries.

Notable Houses
House Caan owns Phobos, and it's sister moon, Deimos.

History
Little is known of the history of Phobos. At some point, House Caan purchased the deeds to both of Mars' moons. Phobos is also commonly acknowledged to be where the Rising began, with the Reaper's speech.

Recently, the Solar Republic has been modifying the dockyards into shipyards.
