The Tal'Akkuran Republic is a nation located primarily in the Sagittarius Elliptical Dwarf, with a few colonies in the Milky Way. They are a mostly peaceful state, as they generally have little contact with other large empires and are generally quite pacifistic. They are renowned for their culture and sophistication, as well as an incredibly robust and effective administration. The main species within it are the Tal'Akkur.
The Tal'Akkur are a very culturally diverse and yet unified nation. They are very accommodating to other people and their is essentially no strife of any kind within their community (there is disagreement, but this is always taken good-heartedly and with respect). They often incorporate small nations, some that have not even reached K1 into their nation, and as such a large portion of the population, especially in the farther reaches of the Republic, is largely of non-Tal'Akkur. If a world is inhabited by a very warlike species, they can generally be neutralised and then incorporated, growing to the same level of respect as the Tal'Akkur over a few generations and having virtual reality arenas for them to keep on practicing their culture. All nations are treated that they are unique and can keep on living how they like, but in harmony with the rest of the Republic.
While they tend to be either atheistic or deistic, some religions still exist, although most of these have very much in common with deism and holism.
Tal'Akkur tend to be quite ecological, and there are multiple zoo complexes within their empire, each housing billions of animals in their natural habitats. The largest is a ringworld system entirely devoted to animals, and hosts millions of ecosystems from across the universe, often with millions of specimens of individual species within them. All in all, it is home to trillions of beings larger than flies, and possibly quadrillions when insects are included, sextillions if including smaller lifeforms. It is constantly being expanded, and is about a quarter-way to completion.
Arts are beloved and huge fraction of the population either makes or just enjoys arts made by others. They are masters of sculpting, painting, cinematography, writing and much more, and their art is generally regarded as the best in the universe. Some of their sculptors are so precise that they sometimes need to use sight-enhancement (usually goggles which act as microscopes, but some of the most devoted sculptors replace their old eyes with artificial ones). The industry is so huge that artistry makes up their biggest export and is sold all over the universe, though this tends to be the less intricate and interesting art which not even all of them can appreciate.
They love languages, and linguistics is a very popular field. Most Tal'Akkur can speak multiple languages, usually those of the races they usually come into contact with, and their voices are well suited to lots of different vocals.
