URR'UHRST̪θ' (Origin Point)
In hoku astronomy, Degazaakoza'pa (Dgazakzp) is the brightest system in the Sailboat constellation, during the summer in the southern hemisphere this constellation stands above the horizon pointing south, forming the base of the greater sail part of the boat. But across the Dominion it attends for its endonym Urr'uhrst̪θ', better known for its Human approximation Argost, and for Hoku travelers as Arihu'risitch (Arihurisit).
The name Argost actually refers to the homeworld of the Arrene, but this became a misnomer amongst their stellar neighbors, like mistaking the 'solar system' for 'Earth'. The star's actual name is noted down as Aa Rithel, or "The Sun" in common arrene.
Aa Rithel is an old single orange dwarf, and stars like it are found all throughout the Dominion.

PLANETARY SYSTEM
Aa Rithel's system possesses five planets, and one brown dwarf.
b) Unnamed rocky planet
A Mars-mass airless rocky world, its cratered and scarred surface is very similar to Mercury's.
c) Unnamed Venusian planet
A superterran wet Venusian, its high surface gravity didn't allow for the star's radiation to blow its atmosphere away, accumulating gas and vapors ever since its formation.
d) Ykaga, the Giant
A brown dwarf at 0.6 AU, 16.22 Jupiter-masses and ~10 Earth-radii, its upper atmosphere is full of silicates, metal vapors, and traces of ammonia at 400°C.
It has four satellites: Argost, and three [unnamed] airless worlds sterilized by Ykaga's radiation belts.
When seen from Argost, Ykaga appears 4x as wide and just 1% as bright as the star Aa Rithel, and it never really moves much from a 2°-wide circle in the sky throughout its 14-day orbit, due the moon's slight libration and orbital eccentricity.
The magnetic field of Ykaga bombards the Argost's poles with intense radiation, which creates beautiful extensive auroras, but can be detrimental to lifespan of lifeforms not native to the planet.
e) Argost, Origin Point
A terran tropical world orbiting at 4.27 million kilometers from the brown dwarf, at this distance the planet receives 0.72x solar constants from its brighter parent, the mean surface temperature fluctuates between 50°C and -5°C through its orbit around Ykaga. Being 2/3rds of the Earth's mass and 90% as large, Argost's gravity lies in the comfortable zone for every sentient race in the Dominion. Its day duration is almost the same as its 'month' around Ykaga, about two weeks.
From orbit, the planetary surface that is able to peek through the stormy cloud cover and dense atmosphere displays continents vastly dominated by urbanization projects, speckled with clean-cut preservation and farming zones for nearly the planet's entire exposed continental shelf. Better described as an oceanic ecumenopolis.
At the terminator of the planet, 100-200 km/h winds blow cold air from the nightside into the dayside, creating twirling storms which propagate about the hotter hemisphere until dissipating. The urbanscape however, is adapted to this wind regime through architecture via aerodynamic designs and one-way disspation valve-like urban layout, in order to break winds and rain down to a light breeze and drip down in the dark lower levels of the cities.
Although present day Argost presents itself as a continent-sprawling and layered urban metropolis under a polluted sky, it hasn't always been like this. The planet used to be much more rich in wilderness and natural landscapes. However, with the aftermath of the Qiro-Arrene wars leaving the planetary surface completely razed and devoid of life. A myriad of arrene astrobiologists, architects, and urban planners, and colonial development jumped from all across their diaspora to rebuild and reterraform the surface however they saw fit. It took over five hundred years of continuous work for permanent populations to be again settled on the capital of the Arrene Combine, now, also the capital of the Foundational Dominion.
TRIVIA & LOCATIONS
The political and economic capital of the Dominion is pretty well defended by hundreds of orbital defense platforms, inhabited by the wealthiest individuals of the Dominion apart from the arrenes themselves - but in such a wild and competitive place, there is no comfort without foul play. The descendants of bankrupt visitors and travelers overflow slums all over the place, its criminal and police brutality are unrivaled by anywhere else in the Dominion.
On Argost, as well as many capital worlds across the Dominion, the major cities form huge interconnected environments, with 30 to 100 million inhabitants, plus a few percent of travelers from across known space. The chaotic and stratified nature of the local society is a key piece of what keeps Argost and many other worlds under arrene control, keeping the rebels at bay with hunger and fire, while petting the grateful so they don't rebel.
The largest and most populous city on the planet is Aa Iritesh'akar or 'The Enlightened City', it was initially built as a spaceport city to welcome visitors from the stars, being expanded over many millennia to accommodate more and more immigrants and their brood, some say that it hasn't completely lost its shine, you just need to stare at it a bit longer to see.
Getting things, products, and weapons out of any arrene spaceport is not difficult, a myriad of licenses is often needed for that though, the hardest of which is to pilot or transport any pieces of arrene tech newer than some 500 years - as long as those weapons are not engaged in prohibited space, armed travelers will be spared of a really bad time. Contrary to the rest of the Dominion, clone-presence is minimal to non-existent in the capital, AI presence is unrestricted however, with many platforms working manual and tiring jobs for their owners as a form of extra income.
Although isolationist as a whole, many arrene groups and individuals show great interest in the affairs of aliens, both in their homeworld and across the Dominion, those more interested individuals work hard to be sent to outworld prefectures, science expeditions, or just opt to straight-out live and trade amongst commoners - living in rather high standards, of course.
