Raalgon

The Raalgon are an advance race of elvish-like humanoids who had declared war on humanity sometime around 2200s.

Biology
Raalgon biology outwardly is not that entirely different from humans other than they are physically more stronger and long lived. But their insides are totally different to the point where human doctors have no way to treat Raalgon patients. They also have long ears giving them the ability to hear over long distances. Most members of this species are known to have red hair.

Society
Their government, The Holy Raalgon Empire, is ruled by an emperor, currently empress Azalyn Goza XVI, and a court of advisers. The Raalgon empire controls a vast amount of planet rivaling that of their enemies, the United Planets Space Force.
