3. Species and population
The Star Kingdom holds about 18,762 trillion citizens. 83.62% are Terrans while the other remaining 16.38% are Cheunh. The Star Kingdom is responsible for their protection be they Terran or Cheunh. The Cheunh were peacefully annexed in 1593 PD through the Cheunh Compromise and have since then proved worthy of the Star Kingdom.
The Terrans are your standard humans from old Earth. However, there may be some small variations such as height due to the varieties of inhabited planets. It is considered quite rude to call a Terran a human, this is because they prefer the name Terran as a reminder to the proper name of Earth, Terra.
The Cheunh on the other hand are a bipedal humanoid species, with blue skin and glowing red eyes. They are very similar to Terrans in appearance, but there are some other differences. For example, they mature twice as fast as humans and are considered elderly at the age of 60 Terran years. They also tend to breed slower than the Terrans, but this seems to be due to cultural norms.
