Phobos

Phobos appears in Red Rising Saga.

Phobos, the diminutive moon of Mars, emerges in the Red Rising Saga as a fortified pincushion city and critical defensive hub orbiting the planet, anchoring the Society's fleet amid escalating galactic conflicts. Though absent from early narratives, it gains prominence in later books as a strategic stronghold, symbolizing the shifting tides of power from the Rising's rebellion to the brutal wars of the post-Society era. Its role underscores Mars' vulnerability and the relentless push-pull of territorial control across the series.
