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.

Aetnaeus's ruddy, red-brown landmass contrasts sharply with its deep navy blue seas. It was one of three planets located in the Tagna system, joined by a pair of rocky hothouse worlds caught closer to their parent star.

As the war with the Ascomanni progressed, the URA’s tactics and strategies were refined to give the forces of the Republic the greatest chance possible to overcome the advantages held by their adversaries. These would focus on making the most of their available forces, while misleading the enemy to the greatest extent possible.
