Creating an Empire: The three main races

So over the past 2 months I have been working on my own Interplanetary empire. Much like Snow's own creation. So I thought Id share the basics of it by giving you a rundown on the 3 main races of the empire known collectively as the Vanithian Empire or The nine sun Empire. Called these because the ruling and biggest race are the Vanithian's and the Empire stretches across Nine solar systems. They will be listed from the biggest population to smallest:

Name: Vanithian
Flag:

Population: 65 Billion
Home planet: Vanithia
most prominent Role/s: Rulers and upper class
Appearance:usually Tanned Skin with brown hair and dark brown or black eyes. somewhat muscular but not as bulky as the Caligate's. Men usually stand around 6ft2 while women are around 5ft8.

Name: Caligate
Flag:

Population: 53 billion
Home planet: Legiore
most prominent Role/s: all parts of the Armed forces
Appearance:usually Dark skin with Black hair and piericing Green eyes. Extremely muscular so much so they can drag two tanks by the barrel and drag them with ease. Men are around 7ft while women are 6ft8

Name: Enrudios'
Flag:

Population: 31 Billion
Home planet: Heavilila
most prominent Role/s: Religious workers
Appearance:A hard one to describe properly they are a creature made from both crystal and organic tissue. Though the organic tissue can only be found on the hands and feet. They have pure white reptilian eyes.

Spoiler: Enrudios
