Aava

Aava are an omnivorous humanoid species that are native to Scylla. They are the oldest sapient species in Scylla, having existed for millions of years. They witnessed the rise of the Ishtarrians and the Ishtarri Empire, having helped them to develop before the galactic civil war known as the Four Hundred Year War.

Biology and appearance
Aava have a unique and complex physiology. They are mono-gendered, having the outward appearance of a typical female mammal. They are oviparous, laying soft womb-like "eggs" halfway through the pregnancy in batches of 3-5 on average. They possess elongated skulls which house their large brains and advanced sensory organs which make up for their lack of external ears. Because of these large brains, they are highly intelligent, possessing acute problem-solving skills and are highly logical. Other distinct features include their pronounced spine and ridged nasal bridge, they are also hairless and possess silvery metal teeth.

Aava have a robust lifespan, living upwards of 1000 years. Due to their scientific advancements in medicine, they are afflicted by almost no diseases at all. Aava reach physical maturity at 124 years of age, this is about the equivalent of age 19 in Human biology.

Aava have a universal reproductive system, meaning they can reproduce with any species and any gender, though the offspring will always be Aava. They do this through a process similar to parthenogenesis. During reproduction electrical impulses are transmitted through the skin from the partner to the mother, which help to randomize the DNA of the offspring. Aava produced from two Aava parents are known as "true-bloods".
