The Twin galaxies sometimes referred to as the Twin galaxy, silly yes I know.
A merger of two massive spiral galaxies.
Made up of both The Milky Way and The Andromeda galaxy. An amalgamation of roughly 1.5–2 trillion stars and upto a 4 trillion planets give or take but when numbers get that large do they even matter.
1)GALAXY STRUCTURE
Two massive spiral Galaxies overlaping, most of it is actually uninhabited.
Where they meet at the center makes up the bulk of its habitable worlds, this is what is actually referred to as the Twin Galaxy most of the time.
It is divided into five massive circular regions of space namely:
Voidrilan –Center where two super massive black holes are located largely uninhabited.
Andralan– the more opulent and well
developed core worlds
Westerlan–planets that are still extremely rich as well as important to the Golden moon and USC but not as valuable as Andralane planets.
Midlans–an expanse of worlds that make up most of the galaxies population.
Farlans–the farthest away from order and control, the beginning to the true extents of madness of the Twin Galaxies.
Further beyond the Farlans are the Far worlds utter and pure inhospitable anarchy. The grand spine separates The Farlans from the far worlds keeping the rest of the inhabited galaxy safe.
2)SPECIAL REGIONS/FEATURES
The Grand Spine– a massive barrier of etheric energy formed into the shape of a spine, it was created during the 10EA sealing away the Grimveil order and the galaxies greatest dangers. It is told in myth and stories that it created through the ritual sacrifice of hundreds of thousands of Iron Ocean Mages by removal of their spines.
Crimson Mons– 3 red moons that
mysteriously appeared shortly after the grand spine was formed shattering it partially and leaving a gap. Strange occurrences regularly happen here it is associated with a wide array of occult topics.
