Mirriam has a tainted, unbreatheable atmosphere and little available surface water. The system supports a population of fewer than 10,000 sophonts. It is a member of Third Imperium in the Vilis Subsector of Spinward Marches Sector and in the Domain of Deneb. Mirriam, as a member world of the Third Imperium, holds the estate of an Imperial knight, a member of the Imperial Nobility charged with overseeing the world. This world has a nearby Imperial Naval Base, capable of handling warships.

Astrography & Planetology

Mirriam is an unremarkable world, inhabited by a few isolationist colonists who have developed a partial immunity to the airborne bacteria that plague the world’s surface. The locals live in scattered farming communities all across the planet, and are quite happy to be left alone.

History & Background (Dossier)

On Mirriam’s single moon is the vast naval base, a heavily armored structure defended by a ring of deep-site meson guns and missile emplacements. The base has its own defense squadrons – fighters, system-defense boats and a few powerful monitors – to prevent a repeat of the events late in the Fifth Frontier War, when a Zhodani squadron made a fast raid while the fleet was elsewhere engaged.

Elements of the 193rd Fleet are hosted at the Naval base.

History: New Era

Disease-ridden Mirriam was placed under military control after the Quarantine. The system's naval base had been a strategically important facility during the Frontier Wars, and the Regency wanted to prevent the installment of Arden (Spinward Marches 1011) associated terrorists and rabble rousers within the population. The world is not a popular duty station for naval personnel.
