Designing for a Low Gravity Environment

When designing for Minimal G, consider the conditions of the planetolgy especially the gravity. Lower gravity means easier flight with less power needed to keep aloft. I imagine ballons would be a cost-effective choice. Less weight means larger vehicles can be made and less mass to sink into the ground. Boats would be more bouyant. Hovercraft would be a good choice for any environment. Walkers would probably need less leg-support strength to hold up their bodies.

The Miminal G 'Look'

While the story takes place a thousand years in the future on a distant planet, consider that the planet has been cut-off from civilization for 100 years and has needed to come up with most designs out of necessity based on the environment. Try to keep the look mechanical without a lot of streamlining. The basic idea is 'form follows function'. Look up "Steam punk" and combine that with whatever faction you're designing for.

Minimal Technology

Since Trocken was immediately colonizable, the need for vast amounts of technology used in terraforming were not imported. All arrivals, people and cargo, first passed through checks in space then on the few spaceports on the surface. Weapons were banned except by law enforcement and military personnel. During the revolution, most large weapons attached to spacecraft were destroyed along with most of Trockens planetside scientific and manufacturing facilities. As such, new infrastructure needed to be created from scratch. A brief "dark ages" occured after the wormhole collapse while the population rebuilt.

All anti-gravity technology is too large to fit into anything but large ships. The smallest units are the size of a large house. Some survived in transport ships that were not destroyed and other units were scavanged from wreakage.

Since manufacturing facilities to process fuel needed for rockets were destroyed, rocketry on a vehicle-sized scale is uncommon. Instead, other forms of propulsion, engine, turbine, etc, were commonly used.
