Before humans invaded the Red Ocean, the dwarf galaxy enjoyed a long era of peace and stability.
The 13 major alien races of the Red Ocean had already carved out their respective territories a long time ago. Waging war on a civilization-wide scale did not make any sense because none of the races could overpower each other quickly enough to prevent others from interfering in the conflict.
Every race implicitly or explicitly maintained the status quo for that reason. This produced a relatively internal state of the multiracial galactic community where the only incidents of fighting came in the form of small controlled conflicts and lawless activities.
This galactic state happened to match the state of the Milky Way before the Age of Conquest.
The Seven Apex Races maintained a persistent balance of power and mostly remained content to rule over their own separate star empires.
