Constantly pulled to its breaking point and baked by the intense solar discharge of its parent trinary stars, Enaria is the physical embodiment of the Umbrians' mythic underworld. Active vulcanism coupled with its eccentric orbit around its parent stars ensure that what solidified surfaces manage to form are constantly in motion before being subsumed back down into the molten mantel of this hellish world.

Ceilomina was the administrative center of the Vaghus system, whose four baren planets orbited around their parent blue giant at significant distances. Originally considered inconsequential by the Republic explorers who first discovered it, the settlement of other nearby systems would lead to the establishment of a small refining station, which was capable of refueling the freighters and colony ships that plied the surrounding star lanes.

When considering worlds for potential colonization, the Republic has created a standard two-factor classification system known as the habitability gradient. This alphanumeric value is vitally important for those who seek to settle on or exploit new worlds, as it directly impacts both the private sector and governmental support they are likely to receive for their efforts.

In a relatively empty corner of space just beyond Tratirne, the Umbrian Republic navy happened across a system with tremendous value: a blue supergiant, almost magenta to the naked eye, with a single planet and an expansive debris belt. The planet, named Aurae, contained rich quantities of helium three, while its moons had properties that made them conductive to Umbrian settlement.

Despite its inability to support life, Asciano has the unique distinction, for better or for worse, of being one of the most well-known planets in the Frontier. It is considered the greatest boondoggle in Umbrian Republic history or, alternatively, a testament to Umbrian ingenuity and willingness to push the boundaries of science.

'A swirling vortex of heat and smog.' Those were the words originally used to describe Anconna, and they were a fair initial assessment of the tempestuous world. A near miss from a habitability standpoint, it orbits too close to its parent red giant. The world's environment likely changed dramatically as its parent star evolved, but any trace of a less brutal past have long since been swept away by the forces of the planet's crushing atmosphere or its active vulcanism.
