Andromeda Galaxy

Andromeda (Imperial Standard: Galaxia Andromedae) sometimes called the Andromeda Galaxy, or more commonly the galaxy by its inhabitants, is one of the billions of galaxies in the universe and is where the Empire of Thodron and various sentient species such as the Thodroni and Dravulpians make their home. It has seen many turning points in history, such as the establishment and fall of the High Republic, the first Nekkyri invasion, and the Great Civil War.

Astrography
Andromeda is the largest in the Local Group in terms of diameter. It measures 220,000 light years across its surface. Its closest and largest neighbors are the Triangulum Galaxy and the Milky Way, the home galaxy of the humans and the Terran Alliance. The galaxy has a number of satellites, numbering over 20 dwarf galaxies, two of which are M32 and M110.

Entospace
Entospace is a circular area encompassing worlds inside the bright galactic core region. Not many habitable planets are located here, but one notable example is Alecar. Hyperspace travel is dangerous here, as stars are often tightly clustered together, especially at the very center near to Ultima, Andromeda's central supermassive black hole.

Sentrospace
Sentrospace is a region encompassing Entospace, and it serves as the galaxy's "capital region". Thodron, along with other wealthy and important planets are here.

Dactylspace
Dactylspace is the farthest region away from Ultima that is still located in the galaxy, and it is also the largest region in terms of area. This region isn't quite as populated or developed as the two areas above, but the majority of Andromeda's planets are located here.

Exospace
Exospace is the area outside Dactylspace and the rest of the galaxy. Outside the very edge of Dactylspace, where all of the few mapped worlds have been found, is the empty expanse between galaxies.

Early history
Andromeda was likely formed around 10 billion years ago after the collision and merging of several protogalaxies. Over the billions of years to follow, life emerged, giving rise to ancient interstellar civilizations and empires that are now long-gone. They left behind remnants of their spacefaring technology which would be used by younger species countless millennia later.

The first major galactic empire was the Yaer'aed Empire, which was established c. 7900 AE. Not much is known about it today, as many of their records haven't survived. Their influence spread to cover likely about one third of Andromeda at its height. Its most notable influence is that of the Thodroni, as their language and some technology have significant Yaer'aed origin. The Empire and its founders vanished without explanation around 2000 AE.

Thodroni would develop far more significantly due to the Yaer'aed, and many important historical events would come soon after, such as the First Divine War and the coming of Aptasian.
