Mysterion

The Barrier is a massive nebula that dominates the western region of the Sirius Sector and makes up for most of Bretonia space and its respective Border Worlds.

Regions
The systems that make up Bretonia mainly have asteroid fields containing either mineral-bearing rock or ice. The Manchester and Cambridge systems have mostly ice asteroids and nebulae bearing Water, Oxygen and Hydrocarbons. Several outcroppings of The Barrier lie in the Independent Worlds between Bretonia and Liberty.

The Tau Border Worlds north of Bretonia are deep in the heart of The Barrier. The Tau-31 System lies within a huge asteroid belt of ice crystals, most of which is too impure for mining save for a few pockets mined by the Independent Mining Guild. The Tau-23 System is within a belt of rock asteroids, with pockets bearing Berrylium and Niobium mined by Bretonia Mining and Manufacturing and the IMG, respectively. The Tau-37 System, the most notable of the Tau systems, is found at the center of a vortex at the end of the Nebula. It contains two nebulae, one with Niobium-bearing asteroids and the other containing water ice.

There are also two Omega Border Worlds that lie near The Barrier, them being Omega-3 and Omega-5. The Omega-3 System contains mostly water ice asteroid fields, but there are two fields bearing Hydrocarbons mined by BMM and Daumann Heavy Construction. Omega-5 is within a massive asteroid belt devoid of any mineral resources, but contains several Jump Holes to other regions in Omega and one to Cambridge. This system is hotly contested by the Corsairs and Red Hessians, two opposing Pirate factions.
