Native galaxy of Orks and Slayers

There is a galaxy, fairly close to both the Milky Way Galaxy and the Andromeda Galaxy/Galactic Prime, that is the home of the races of the Slayers and the Orks.

It is believed that galaxy was politically fragmented into dozens or even hundreds of political factions led by Slayer leaders or Ork Warbosses for centuries and millennia.

Sometime around 110 ABY, much of this galaxy was united under the Slayer of Slayers and his Slayer-Ork Horde.

After an ultimately unsuccessful invasion of the galaxy of Galactic Prime (also known as the Andromeda Galaxy) from 140 ABY to 145 ABY which saw the Horde almost totally annihilated and the Slayer of Slayers himself killed, the galaxy that spawned the Orks and the Slayers fell into violent, political chaos as rival Ork Warbosses and Slayer leaders fought each other.
