Muslin

The system where the Saint Angevin’s Fury crashed. The ship was bound here are a morale exercise. The local tithes were beginning to slip. The Administratum suggested, and the Navy agreed, that showing one of the “heroes” of the fleet would be a great show.
Sadly, the Fury crashed into one of the uninhabited worlds. The plan backfired and panicked mobs began to flood the streets. Thankfully a preacher, a member of the Cult of St Schule, bled off much of that energy into a plan to colonize the uninhabited rock.
Now “Saint Angevin’s Rest” is a productive mining world, although just as inimical to human life as ever.
Muslin II is the center of the system, a major forge world. It is completely inhospitable- a person must wear a sealed suit outside of the hives or die.
One of the reasons to expand to “St. Angevin’s Rest” was to provide new resources to Muslin II. The great strip mines that criss-cross Muslin II are nearly spent. The western hemisphere of the world is given over to starship components, especially drives. The eastern produces macro industrial tools.
The planetary temperature varies between -40 and +40 degrees Celsius. The days are 26 hours long, but it rockets around the sun, with only 60 days in a planetary year.
Only 700 million people live here, massively outnumbered by the servitors of the planet.
The orbital defenses are extensive, because the surface is too torn up to support any real planetary weapons. The orbital troops are well trained and extensively augmented to interface with their weapons.
Militia defenses and conventional forces are decidedly limited, but the Adeptus Mechanicus Explorator fleet and other support is nearly a subsector fleet in its own right.
Three entire Titan legions are based here. However, only two are regularly home, since at least one is on constant campaign.
