NameDescription
Reflective Cloud ParticlesSeveral strategically placed dispersal facilities spray an aerosol of highly reflective particles into the upper layers of the troposphere. This will decrease the amount of sunlight reaching and warming the surface
MoholesThese holes may seem deceptively primitive at first, but with depths in the tens of kilometres, they pose a significant engineering challenge
Black DustThere really is no more to this than sprinkling dark particles across the surface in order to increase the amount of energy the world absorbs from its sun's rays. The amount of material required is quite staggering, though
Excite Outer CoreIt requires a massive amount of material and energy, but it is theoretically possible to induce sufficient movement in the world's outer core to make it produce a stable magnetosphere
Brake Outer CoreIt requires a massive amount of material and energy, but it is theoretically possible to slow down the flows in the world's outer core, dampening the magnetosphere to a level that is harmless to electronics, while retaining its beneficial properties
Import WaterWithout readily available water sources, there are not many alternatives to importing it
Planetary IrrigationA massive system of canals, pumps and treatment facilities can provide most of the benefits of rivers with a reasonable, if still tremendous, amount of imported water
Global Water SurfacingMost worlds, even seemingly dry ones, have vast amounts of water hidden in subterranean caves and aquifers. We now have the technology to raise and make use of that water on a global scale
Import MethaneImported methane can not only have a positive effect on atmospheric pressure, as a potent greenhouse gas it also helps to warm up a cold world
Methane OxidisersGigantic fans blow the methane-heavy air through filters containing zeolite powder. The trapped methane is then periodically heated to form and release carbon dioxide (Oxidise Methane)
Carbon MineralisersWhen forced through tunnels containing a high surface area of certain minerals, carbon dioxide can be made to crystallise into a solid, removing it from the atmosphere entirely (Mineralise Carbon)
Targeted OutgassingBy letting loose swarms of carbon-eating nanites, we can release massive amounts of nitrogen into the atmosphere. They are programmed to stop at exactly the ideal air pressure
Clean Up ToxinsNow that the sources of toxins have been dealt with, we need to clean up the damage that's been done. It won't come cheap, but at least we'll be able to breathe the air
Volcano CapsThese structures are not mere physical plugs that block eruptions. A variety of systems, including vents and sprinklers controlled by a specialised AI, takes proactive measures to prevent the conditions that lead to eruptions in the first place
Tectonic ScaffoldingLattices of self-organising smart matter find friction points between tectonic plates and release tensions in a controlled manner
Clean Up Radioactive ContaminationSwarms of specialised drones to seek out and gather irradiated substances, enough material to entomb them, and gigantic filters to cleanse the air make this a horrendously costly undertaking. Unfortunately, it is not optional if people are going to live here outside of shielded environments
Tailored MicrobesIt will be a considerable effort, but we can genetically engineer an ecosystem of microbes that is specifically designed to thrive in this world's environment

Jumpstart Microbiome

Why spend money and resources creating the perfect set of organisms when we can make nature do the hard work for us? Sure, basically throwing piles of biomatter around and seeing what sticks isn't very distinguished, but it might just work!

Microbial CullingThrough careful use of antibiotics, both tailored and wide-spectrum, the microbiome must be curbed before productive use of this world is possible
Cyanobacteria

These photosynthetic bacteria can be a vital part of a world's oxygen cycle

Genetically Modify Toxic Fruit

A tailored virus, capable of sophisticated genetic modifications, should result in local fauna no longer releasing toxins into the air
Cull Toxic Fruit

We can release parasites that should eat only the toxic fruit. This will require a certain amount of trial and error, though, and may have adverse side-effects

Cull Parasites

The parasites have unfortunately adapted to feed on other fruit as well. If we don't get rid of them, we will have a much harder time with agriculture

Reintroduce Local FloraThis planet was the home of the sunrise flower and swamp plant that are now staples of the spacefaring Teladi diet. With the conditions for their growth having been restored, we can reintroduce them and restore some of the planet's former glory
Geothermal Power PlantWhile primitive versions of this technology relied on steam turbines, advanced materials now allow for efficient use of the Seebeck effect to generate power from large heat differentials without any moving parts
Wind Turbine FarmWhen it's available, wind power can be a very cost-effective method of generating power
Matter/Antimatter Power Plant

Based on the same technology that powers vessels and facilities in space, matter/antimatter is a powerful but costly solution for planetside power generation

Clean RefineriesThese fully automated facilities refine locally mined resources into various materials

Cheap Refineries

These fully automated facilities refine locally mined resources into various materials. To keep costs down, they have not been outfitted with emission filters
Retrofit Emission FiltersUnfortunately the local minerals contain toxic substances that are being released during the refining process. We will have to stop these emissions before attempting a cleanup

Factories

 

...

These automated facilities produce advanced technology when supplied with materials.

Von-Neumann ConstructorsThese self-replicating drones have been outfitted with logarithmic brakes to prevent a runaway scenario at a fundamental level while still allowing them to react to demand at the proper scale. In addition, they are controlled by specialised AI systems which lack the capability to alter their own programming. This makes them a safe, if less effective, version of the original Terraformer designs.
Hydroponics

While sometimes there is no alternative, this method of food production is much more expensive than conventional farming, and yields inferior products as well.

Fertilise SoilWith a healthy microbiome, we can begin to make the land arable. This requires soil with sufficient drainage, the right pH, necessary nutrients in plant-accessible form, and all of that at a depth sufficient for roots to take hold. A significant effort, to be sure, but absolutely necessary before any large scale settlement can take place.
ForestationPlanting and cultivating large arboreal areas does not just make for picturesque postcards; it can also greatly contribute to a stable ecological system

Wheat FieldsWhile these plants can have a beneficial effect on the global ecology, their main purpose is, of course, feeding the human population.
Sunrise Flower FieldsWhile these plants can have a beneficial effect on the global ecology, their main purpose is, of course, feeding the Teladi population.
Soja Bean FieldsWhile these plants can have a beneficial effect on the global ecology, their main purpose is, of course, feeding the Paranid population.
Scruffin FieldsWhile these plants can have a beneficial effect on the global ecology, their main purpose is, of course, feeding the Split population.

Several layers of self-repairing sheets made from an advanced plastic keep the air inside and maintain a temperate climate, while shielding from dangerous radiation and even micrometeorites. Many complex pieces of technology interoperate to create a stable, even somewhat comfortable environment inside.
