Tivoli is a verdant world of broad plains and vast oceans. Slightly larger than Umbria and orbiting a blue-white main sequence star, Tivoli's climate is temperate and welcoming. It features three primary continents, which together account for only about a quarter of the planet's total surface area, while its endless seas are made up of mildly salinated water.

Battipaglia was the last Umbrian colony world to be settled before the arrival of the Ascomanni, and it would play a tragic role in the two species' first encounter. Discovered in the early 31120's, Battipaglia is a large terrestrial world, blanketed in vegetation and interspersed with large inland seas and white peaked mountain ranges. With a thick, well-oxygenated atmosphere and gravity just over Umbrian-standard, Battipaglia looked like an excellent choice for colonization.

When the first explorer arrived in orbit over the fourth planet in the Druata system, she reportedly said, “We have found Elysium itself. I have no doubt that below we’ll find those legends of old, enjoying their repose on this beautiful paradise amongst the stars.” This description would prove to be apt. Venezia’s oxygen rich atmosphere, warmer climate, and slightly lower gravity would attract colonists by the droves.

A relatively recent find, Varese was only first surveyed in 31134. A quiet world orbiting a red-dwarf star, Varese was remarkable only for the large quantities of heavy metals believed to lie in subsurface veins just under its crust.

Umbria is the crown jewel of the Republic and the homeworld of the Umbrian people. Sixty percent of its surface is covered by ocean, while the remainder is made up of continents and island chains featuring lush vegetation, striking rocky outcroppings, and verdant grassy plains. Its capital, Perugia, is the capital of the Umbrian Republic and home to the Republic's Senate and Triumvirate, or executive body.

Called the ‘Gateway to the Frontier’, Tratirne is a near-perfect facsimile for conditions on Umbria itself. Its surface area upends the traditional distribution between water and landmass, with the former only making up about 35% of the surface’s volume, trapped in broad inland seas connected by narrow isthmuses.
