Well, trying to write more lore and making only very slow progress; we'll begin with the planets of the Anar system.
Anar:
Anar is a sub-giant G class star in the early-mid stage of it's life; surface temperature is in the upper range expected for this type of star, with a mean average of ~5,800 K. Some spectral peculiarities are present, which often lends a surreal cast to the surfaces of the planets orbiting the star. Due it's size, the habitable band around Anar has pushed out from the center of the system, when compared to Sol.
Lambence:
A mostly uninteresting ball of dust and silica, Lambence is tidally locked with Anar. Home of a mostly automated power generation facility, this tiny world is both the start and end point of a stable, but very low profit margin, trade route centered on the exchange of high capacity energy storage.
Lambence has only a single settlement of any note, Depl, itself simply the pronounced form of an abbreviated thought common among the locals--DEPLL:
"Dear Euripides,
Power.
Love, Lambence"
Wallow:
Wallow is a midsized terrestrial world with a toxic atmosphere primarily composed of carbon dioxide; surface temperature and pressure prohibits effective exploitation. The SRA has made proposals for permanent aerostat colonies, which would be able to extract valuable gasses from the planets atmosphere, but resource limitations resulting from the numerous small scale conflicts across the Persean Sector has prevented these proposals from moving beyond a very preliminary stage.
Euripides:
When first colonized by the Domain, Euripides was almost entirely desert. It's magnetic field is strong enough to prevent loss of water to solar wind, and the current theory is that much of the planets surface water was lost due to repeated major asteroid impacts between 60 and 15 million BCE. Scientific assessment suggests these impacts to be related to the dust ring encircling the planet and its proto-moon Aeschylus, which is believed to have been struck--and effectively obliterated--by a rogue planetoid approximately 60 million BCE.
The relative abundance of water now is the result of what the Domain would doubtlessly consider a very crude method of terraforming--harvesting cometary ice water and landing it on planet through various means. The indigenous flora and fauna, evolved to survive in a near absence of water and in very sandy soil, has exploded across the northern hemisphere which has accumulated the bulk of the additional water.
These efforts at rendering the world more habitable began shortly after the then Shadowyards Heavy Industries selected the world as their headquarters following being pushed out of Merid, initially as a means of, essentially, bribing the colonists into ignoring the outlaw organization; as Domain assistance failed to materialize and the world was continually ignored, the colonists moved from grudging tolerance to actively aiding Shadowyards in their efforts and widespread popular support. Much of the water now present on Euripides surface was delivered in the time surrounding the collapse. Euripides is still barren and dry in its southernmost reaches, and the SRA has not been able to significantly advance their terraforming efforts for the past 140 cycles or so.
Euripides is peppered with well developed cities and towns, particularly around the it's shallow northern Ocean, the Azural Sea, and throughout the Great Basin area. Its capital, and the capital of the SRA, is the city Marion (pop. 128,545,000).
Theramin:
A stormy terrestrial moon, Theramin is protected from intense gamma radiation from the gas giant Calleach due to Domain era radiation absorbers which the SRA has not been able to replicate. As such, despite the otherwise desirable status of the moon, colonization has been limited to a few areas under the protective veil of these massive, arcane devices.
Beyond the monolithic Absorbers, Theramin requires the aid of a pair of large solar arrays redirecting Anarlight to her surface while the world is in Calleachs shadow, and as a result the moon is temperate, if rainy, at nearly all times of the year.
The moons unusual features, in particular the radiation absorbtion towers, has led to it being the location of several major research facilities, founded to study the interplay of the absorbers and Calleachs tremendous output of deadly cosmic radiation. As well, it is also one of the largest collections of special forces units in the Sector, as the necessity of the Domains arcane and irreplaceable technology has led to a commensurate security presence--unsurprisingly, Theramin is also a major training facility for SRA ground forces.
Theramin's name is a result of the distinctive humming noise produced by the radiation absorbers while the devices are under stress; the moon's capital is the city Warble, located around the base of the lynchpin absorbtion device near the moons southern pole.
Theramin is essentially the center of the SRA's military forces.
Calleach and her other Moons:
Calleach is avoided aside from automated gas mining platforms. These cheap aerostats can produce significant quantities of valuable volatiles before inevitably being torn apart by the Giants violently churning atmosphere; retrieving the gasses acquired from this process is a risky affair, and generally the domain of the desperate or foolhardy, and nearly a third of all craft that make the attempt never surface. No attempts at inhabitation have been made.
Cinderbox is in a state of constant volcanic eruption due to her proximity to Calleach; immense tidal forces render the planet an uninhabitable hothouse. This tiny moon is of little mineral worth and has seen no significant effort at exploitation.
Melancholia is a small moon primarily composed of various cryonic materials; it has a thin atmosphere of methane and argon; while a valuable source of cryogenics the planet has seen no serious effort at colonization and most habitats are of a temporary variety, save for a single mostly permanent settlement, Shanty, which is nestled around a supercooled ground-space rail terminus, and which exists mostly to serve the ever shifting amount of small mining concerns on the moon.

Hopefully I'll get the other stuff finished at some point.
Edited 12/16/17 because the information about Wallow was just totally wrong and the aerostat thing never happened.
