Parella
The star system formerly known as HD 10180, Parella is the most crowded star system in the Orion Arm. With nine planets and two asteroid belts all within the orbital radius of Sol's asteroid belt (most within that of Earth), travel within Parella is always complex. The sheer quantity of bodies is not the biggest draw of Parella, however. The eighth planet, dubbed Bridgehub by the Vorans, has many warp bridges, as well as a couple of survivable moons. Life in Parella revolves around this fact.
Redquiet (10180b)
A hot, lifeless rock. Seriously, there's nothing here.

Laylow (10180i)
The thin atmosphere here does not provide enough to breath, but it is just thick enough for clouds to form on parts of the planet. These clouds are highly opaque, and on the night side the atmosphere is even temperate enough to survive. With the planet's slow rotation speed, the same spot on the planet can stay in the dark and obscured by clouds for months, while radiating enough heat to mask thermal signatures from the surface - all this making the planet ideal for hiding.

Pummel (10180j)
This dense rock of a planet is known for its heavily cratered surface. Often used as a gravity slingshot, but largely ignored besides that.

Bridgehub (10180g)
Orbit: This gas giant has in its orbit a number of small moons, two large ones, but most importantly, eight warp bridges. It's the single most connected planet in the network, including direct links to Varhanna and Sol.

Softmoon
The inner moon of the gas giant the Vorans call Bridgehub is hospitable to life, albeit barely. The atmosphere is cold and thin, but does lend itself to snow, which blankets the moon. Underground is more temperate, and all three major species soon establish underground colonies here. The moon's core is warmed by tidal heating from Bridgehub, and primitive algae-like life is native to the moon, and can serve as a food source for colonists.

Parella Station
Parella Station is a marvel of Voran engineering. Its scale is unprecedented by space station standards, especially for one with centrifugal gravity. The Vorans built the station at great expense to enforce the peace treaty and to encourage interspecies commerce and negotiation. Most of the material the station was built from was mined in situ from a small shepherd moon in Bridgehub's ring system.
The station's environmental controls are set to a level that is compatible with all of the known speciess, although privately leased areas have environmental controls allowing more comfortable TMP and ATM levels. (The GRV can be adjusted by migrating to the inner layers of the cylindrical station.)
The orbital environment near the station is strictly controlled. When in rendezvous range, all weapons system are required to be fully powered down, and speed is strictly limited to prevent kinetic attacks (and accidents) against the station. The Unification Charter fleet guarding the station is notoriously strict, and any deviation from the travel regulations is punished with a shoot first, ask questions later mentality - the safety of the station is paramount..
The station itself has a capacity of approximately 700,000 humans, 700,000 Bactarans, 200,000 Guigu, and 1,200,000 Vorans, including approximately 150,000 hives. Appriximately one-third of these beings are part of the Unification Charter fleet. At first, its traffic is bolstered by being a mandatory waypoint for inspection for any vessel traveling between the warp bridges. As the artifact hunts heat up, the treaty is disregarded more and more until finally it is dissolved; the station's Unification Charter leadership, however, lobbies successfully to be considered an independent governmental entity to which any sentient being can apply. Parella Station becomes the UC's first independent territory.

Farmoon
The outermost moon of Bridgehub is of habitable temperature for humans and Guigu, though too cold for Bactarans and Vorans. This moon's orbit intersects a thin, dark planetary ring, which deposits dark material on the leading edge of the tidally locked moon. This causes that hemisphere to be slightly warmer than the rest of the moon, bring those areas into warm enough temperature ranges for farming.
Given its proximity to the warp bridges (and eventually, to Parella Station), combined with fertile soil, it soon becomes the breadbasket of the system. Human and Guigu farmers flock to the moon, seeking a new life and healthy profits selling food for all species; the moon becomes known for the strength of the human-Guigu relations there.

Leviathan (10180h)
Orbit: This large, distant gas giant has a veritable fleet of small, icy moons, often mined for water and fuel.
