Traveller is a gas giant located in the Aleph Cluster. Traveller itself is an inhabitable place, but the many moons which orbit the planet have been terraformed into colonies. Managing and maintaining these colonies is the responsibility of the Unity Protocol, and the citizens living on them. At least half of the moons are colonised.

The band of space Traveller orbits is host to the Entropy Bias phenomenon, where interdimensional phenomena are more likely to occur in the vicinity of the planet and its moons. This phenomenon is exploited by the Unity Protocol to stay culturally vibrant, up to date with many different technologies, and keep it challenged by new arrivals friendly or otherwise.

The following moons of Traveller are colonised for living. They are more than 80% terraformed by Units over the span of years, to be able to support life in 1G¹⁾ of gravity. Colonies are suitable for a majority of life forms which call Unity Protocol home.

Considered the capital world and central server hub of the Unity Protocol, Unity Prime is a primarily utilitarian colony with the express purpose of hosting the infrastructure that allows the Unity Protocol to run effectively.

A sub-tropical colony situated on a forested archipelago, Sargasso is home to Sourcia and other aquatic species, in addition to a bustling city on the coast and spread out through two islands. Sargasso is frequently subject to strange, localised phenomena, and the locals usually blame it on the way things are and roll with it if it benefits them.

A primarily agricultural colony, Shade is responsible for providing food and vegetable matter many of the other colonies that cannot adequately supply themselves with the food and land necessary. Some portions of the planet are untouched and turned into plant and animal reserves for medical research.

This colony-moon is host to green forests, rolling meadows and farms, with villages dotted around every ten or so kilometres. Intended to be a planet-wide retirement and relaxation community for the elderly and retired, Nonna also enjoys being named one of the most relaxing places in the Aleph Cluster, and holidaymakers regularly have picnics in Nonna's many parks and fields.

This heavily urbanised colony is an experiment in deregulation and looser laws. What the Units found was that those with more power, wealth, and influence exploited everybody beneath them, and they have created a densely packed city with terrible air, cagey and impoverished people, and an export of criminals and people whose poor decisions follow them throughout the Aleph Cluster. Units frequently find their hardest work in keeping a community together on Noir.

Bias gets its name from an elliptical orbit, and 'weighted' path of travel around Traveller, and is host to a sandy, dry climate. The presence of thick, heavy dust storms makes keeping complex machinery a hassle, and many residents have found that keeping pack animals is far easier than repairing machinery. To this end, Bias is host to both off road car racing, and long horse races across the shrubland.

A colony devoted primarily to building amusement parks and heavily invested in by private companies and media organisations as a place to film movies and produce other entertainment media, Recreator is a glitzy, glammy, sun-soaked urban area. Content and joy creators of all stripes are given incentives by the local government to keep producing. Residents say that some of the content is examined by the Units, but they keep direct intervention in how it should be produced, or the content's subject matter to a minimum.

These moons are yet to be adequately colonised, or may be used primarily for resource gathering and aren't open to the general population, save for planetside microcolonies. Adventurous individuals or groups aren't stopped from landing on the moons, but the Protocol is not responsible for any misadventure that may take place.

For civilisation to live on otherwise uninhabitable moons, Wind Wall technology is employed. The large walls push a curtain of atmospheric gasses into the air, creating a localised area of temperate habitable land roughly one hundred and twenty eight square kilometres in size, able to grow and sustain a small city and and town. These 'Walled Towns' are reliant on trade and exporting to colonies, and lack resource growth to sustain ongoing population growth, as the wall cannot be expanded without thinning the breathable atmosphere to unsafe levels.

Named after one of the simplest of its exports, Knife is a rocky moon host to mining operations by the Unity Protocol and other private organisations. Occasionally, stories surface of the discovery of old ruins to forgotten things and strange artefacts, drawing would-be treasure hunters to infiltrate the planet. Mining Units and private drones scurry throughout the planet's surface and its crust to gather minerals meanwhile.

An icy ball of rock which stays in the shadow of Traveller, and routinely experiences freezing cold temperatures year round, while pools of liquid nitrogen dribble from the mountains. Underneath the icy exterior and at the feet of craggy mountains is a faintly glowing ocean, with lifesigns spotted but no firm identifications as to what it is, or if it is intelligent made.

The following space stations and other structures are found. Here, the Unity Protocol has no direct jurisdiction, but if any wrongdoing is traced back to a private station, such as organised crime or piracy, they will return with the UDD and a warrant.

A gaudy, attention-getting space station with chequered flags, hot pink, and neon, the One-Stop Servo is a spaceship refuelling and service station with the addition of a restaurant, a hotel, and a recreational area together under the One-Stop banner. The station is capable of serving tens of thousands of customers a day. The regulars have a taste for rockabilly music, and wear Greaseheart aesthetics and sensibilities. All the while, the Servo hosts dance parties every weekend with a live band.
