I've been working on it for about a year, developing parts of the world and even writing a story.
The people who speak [cʰeɮ.mnɔɸ] ("Voice of Thought") are the [cʰeɮ.nɔ] ("Advancers", "Progressors", "(The) Knowing").
The [cʰeɮ.nɔ] originally come from a country called [cʰeɮ.naɹ] and live on the main continent [ˌθʍɔˈɸyːxθ] ("Great Grounds").
[cʰeɮ.mnɔɸ] has long since become the government issued language throughout the worldwide federation.
Everyone is thusly (a) [cʰeɮ.nɔ] since everyone is a part of the federation, broadly speaking.
Other languages are usually on the verge of extinction, except maybe a few, in places where the federation can't get to easily. As such [cʰeɮ.mnɔɸ] with that name is usually the original dialect of the first [ˌθʍɔˈcʰyːɮθ] ("Overking", "Overlord", "High Ruler").
Although the federation might seem somewhat evil, bad or unfair, the [ˌθʍɔˈcʰyːɮθ] is usually very benevolent.
Besides the [ˌθʍɔˈcʰyːɮθ] there is a council on most political matters. Sometimes the [ˌθʍɔˈcʰyːɮθ] seeks counsel from a national council.
They live on a planet they call [ɸax.θaɔ] ("(The) Rock", etymologically made of the roots [ɸax] "Ground, Soil, Rock" and [θaɔ] "(obsolete) Body, Form {Matter}"):

Ice Desert (dark gray)|Tundra (pink)|Taiga (brown)|Grasslands (green)|Steppes (or Savannah)(orange)|Tropical Area (red)|Desert (yellow)|Mountainous Area (white to gray)
The planet is very similar to earth, as would be the concurrent technology.
The people on [ɸax.θaɔ] are humans, though I refrain from calling them that as much as I can, because I want human to mean only a real human.
In comparison, [cʰeɮ.nɔ] are 100 to 200 years ahead of humans.
This is not due to their superior research methods, but due to my choice of the setting being somewhat to strongly futuristic. In other words, the time in their universe is just that little bit ahead, if that explanation even makes a difference.
