The entire world uses the common language, though some regions might have a local accent, like the arrogant accent of the Gafura people, who add some nasal sounds when they pronounce words.
This gives the impression that when they speak, they must have their noses in the air!
The Federation people also have their own accent, as this country is a great melting pot, where almost every race in the world can be found, making the Federation accent more crisp, simple, and efficient.
Of course, some long-established countries secretly mock the Federation accent as a "rural accent," saying only country folks speak so straightforwardly.
Nobles should use some elegant intonations or pronunciations to showcase the traits of superior nations.
However, Federation people don't care, as sometimes they are more pragmatic.
Too many affixes might not express things too crisply; mimicking the Federation's way of speaking is quite simple—just be straightforward.
