From Adventure 4, Leviathan:
Belgard 0306-D371321-9 M Non-industrial G
The name is probably a corruption of Beauregard (see Library Data). There will be at least one student of Imperial history in the crew who may make this connection. Though a starfaring community, this capability - and other technology -is conducted with obsolete equipment, either much repaired originals or unreliable copies. Actual tech level ability of the world is 6. The community (in one large town with outlying agricultural and ancillary settlements) is known as the Belgardian Sojourn, its origins lost in myth and legend. Other starfaring humans are generally regarded as the 'Enemy'. The Sojourn wishes only to be left alone.
Much of Belgard's natural resources have been ravaged in an unplanned, callous manner, as the Belgardians do not see the planet as their permanent home. However, prime trade goods are animal pelts, precious gems and most importantly, naturally occurring zuchai crystals (see Library Data).
From Library Data in Adventure 4, Leviathan:
Beauregard, Captain Argon Kevin: Generally held to be responsible for the defeat of the Empress Marava in the Battle of Sulgami, 620, by Ivan, who was subsequently proclaimed Emperor. Beauregard was commanding a Fleet Carrier in the Reserve Division when, through enemy action, command of the Division passed to him owing to seniority. When a large force of Ivan's Strike Cruisers broke through the main line, Beauregard jumped his ship to safety and left the Division temporarily leaderless. Marava's position became untenable, and she ordered a wholesale retreat. Beauregard afterward claimed he had undergone a 'religious experience' during the battle, and wisely chose to quit the lmperium before an organized pursuit could be mounted. Though connected with certain acts of piracy along the Outrim, his final destination and fate remain mysteries.

Using Deep Space Exploration Handbook (MgT 2) extended system generation. Backed The Rift Kickstarter and happily reading that, wanted to try out its rules somewhere. But fitting the existing data, regarding it as 'already chosen' on the relevant tables there.
Choosing Binary - distant companion as system type to fit with existing data
10 worlds total (existing data) - say 8 around primary and 2 around companion
I am also using a mix of tools to make other calculations, including the MegaTraveller World Builder's Handbook, Artifixian YouTube videos, World Building for Writers, Gamers and Other Creators by Matthew Selznick, all assembled into a spreadsheet I have for this purpose.
Having said this, I shift data points around freely to get the planet as pictured in my head. But doing this gives a (hopefully) more internally consistent picture of a world - shifting one data point shifts others in interesting ways.
For example, I upped the density of the planet deliberately, and shifted the planet out until it was past the point where it would be tidally locked. This makes the world colder - an average of -9 degrees Celsius - but with an equatorial temperature that is more moderate, implying a settlement near the equator.
Primary (K8 V) - using real-world data to get luminosity, mass and radii to make Traveller-relevant calculations.
Luminosity: 0.083
Mass: 0.62
Radii: 0.61 (solar radii)
Radius: 424799 km
Safe Jump point: 84.96 million km / 0.57 AU
HZ = 0.2881 AU
Roche limit = 0.006 AU
Frost Line = 1.40 AU
I followed the Deep Space Handbook in randomly generating the bodies, re-rolling Gas Giant and Planetoid Belt results when all GG's and Belts had been placed.
I randomly generated the distances from the primary by multiplying the AU of the first SGG by a randomly determined value between 1.4 - 2.0 and did likewise for each succeeding body. This gives a picture of travel times between system bodies for wilderness refueling or options to explore elsewhere in the system.
Nature of bodies (K8 V):
Belgard (main world) - 0.46 AU
