White City

The White City was the religious and political capitol of Mars, ruled by its High Imperatrix. It was the seat of power for the Mothers during most of the Genetics War, only changing hands towards the end of the twenty-year struggle (nearly 38 Earth years). It was the scene of the Battle of the Last Day, and the only safe place after the detonation of the iron oxide bomb. In the series, the words "the White City" refer not only to the physical location, but also the ruling government, as well as prevailing social norms.

After the war rendered the planet inhospitable, it was the White City that determined which Daughters would colonize which planets. It was also the scene of massive, bloody purges targeting apostates, heretics, and empaths.

Unbeknownst to the Daughters of Earth Colony, the White City and its inhabitants were apparently destroyed by Nisja of Titan.
