The development of clean, safe nuclear power was one of the most significant developments in the history of the Republic. Initial fission plants offered significant improvements over various combustion-based alternatives. However, fission plants produced radioactive waste which was expensive to dispose of and had significant half-lifes, the time it takes the material to expend its unstable energy through radiation.

Even with the ever diminishing size of power plants, the energy needs of the Republic's advanced technologies continue to require the abundant availability of cheap and efficient fuel. These fuel sources take two forms: the first being used to power the fusion reactors which are ubiquitous across the Umbrian technological landscape, and the second being antimatter, the exotic particle whose energetic reaction when combined with normal mass is necessary to support supra-luminal travel.

Long considered the realm of science fiction, the ability to manipulate gravity would gain traction following the confirmation of the existence of the graviton, and eventually, the antigraviton.

Umbrians are an advanced bipedal mammalian species which developed on their homeworld of Umbria. They have created an advanced society predicated on the use of technology to solve the problems of daily living in large communities. Art, science, and architecture are some of the most important facets of their shared culture, and society is generally managed through collaboration and consensus than the application of force.

Umbrians have long seen the design and construction of buildings as a masterful expression of practicality and artistry, merged together to create spaces that are both inviting and suitable for purpose. Umbrian architecture is varied in style and design, but a few key reoccurring concepts can be found throughout the Republic.

The Umbrian Academy of Science is one of the most illustrious professional organizations in the entire Republic. Nearly as old as the formation of the Republic itself, the Academy has drawn the brightest minds in math and science for the better part of four hundred years.
