The Lower Spiral

The Lower Spiral
The Lower Spiral is the "lowest" of the three Spiral Arms of Solonae, and is also the most dangerous.

The Lower Spiral is populated, and controlled, almost exclusively by Scourge, with their suspected homeworld - "Sector Zero" - believed to lie deep within. Every other spacefaring species has been systematically exterminated as the Scourge extend their Hive Fleets towards the other inhabited sectors of the galaxy.

The Lower Spiral is considered off-limits to all but the most insane military excursions, and the border between the Spiral and the centre of the galaxy is littered with the corpses of gutted and destroyed warships, the victims of dozens of failed attempts to find and destroy the heart of the Scourge advance.
