Subsector F of Spinward Marches Sector. Vilis Subsector is the communications link extending along the Imperial border from Regina. A chain of Imperial worlds plunges through the heart of the the subsector. While the coreward portion of the region is a demilitarized neutral zone shared with the Zhodani Consulate, the rimward edge of Vilis borders on the loose confederation known as the Sword Worlds. In times of tension, the exposed location of this subsector makes the area a prime military position.

The Vilis Subsector is defended by 23rd Fleet until the Fifth Frontier War and the 193rd Fleet thereafter.

Physical Astrography

The following astrographic features and trade routes can be found within this subsector:

• Spinward Main

• The brightest star is the red giant primary of the Frenzie system.
• It contains the Abyss Rift, a region of lower stellar density.

Stellar Distribution

A basic map showing the distribution and size of stars within Vilis Subsector.

• The color corresponds to the visible color of the star, which links to its spectral classification.
• The size as shown indicates both the physical size of the object and its relative brightness.

Note that the stars as depicted are representative. Any star, no matter what its size, is a mere speck within the hex it occupies.

• Ordinary main sequence stars can barely be seen from even a hex away.
• Huge, intensely luminous giant stars can be seen from across the subsector and far beyond.

Rifts

One rift region lies within the subsector:

• Abyss Rift

Trade Routes

The Spinward Main

The Spinward Main is the arterial trade route within the Spinward Marches. It passes through Vilis Subsector.

High cargo capacity, low jump rating vessels laden with goods, commodities, and luxuries move along it, bound for the thriving markets of its member worlds.

• Worlds on the Main are marked in green.

Local Worlds

The worlds lying along the coreward edge of the subsector are members of the Main.

A single world to rimward, Margesi, lies on another branch of the Main.

• It is associated with the Daryens, the Sword Worlds, and the Entropic Worlds.

Major events that have affected this subsector and the wider region that it lies within:

• circa -300,000: the Ancients are active within the sector, most notably transplanting humans from Terra onto Darrian.
• −5823: the Zhodani Consulate is established.
• -4045 to -2204: the Vilani Ziru Sirka controls vast territories.
