These are the Chimerans a species often made by mages or scientists, unfortunately often made for free labor, they tend to be short and bottom heavy since imps are the most comment template to create them, as it takes up the least bio-material, but come in other shapes and sizes.
Chimerans made for these more selfish purposes often experience health issues as a result, magic-born chimerans moreso than science-born, as they are more "polished" but still not perfect when it comes to health.
But unfortunately they're often thrown together, without much thought for compatibility, This is because they are often thrown together for the positive traits they want for the labor they make them for, not minding the downsides of possibly incompatible parts.
one of the most common issues is an oversized digestive system, leading to a potbellied appearance.

But they are of course sentient beings with personalities and desires, there was in fact a massive rebellion, headed by Peleus (left) and Cade (right), they stole the large ship they were on with a small, well-organized army of their own people, landed on a mostly unused terraformed moon, The moon was one of the moons orbiting the Asternereid home planet, the Asternereids, not having properly used the moon for lifetimes now, granted them full reign of this moon, and do trade with them.
The moon was named DeLacey, after the blind man who showed Frankenstein's creation kindness.

And so Fleeing chimerans will often make their way to this moon where they are taken in, and protected from recapture, there is also proper medical care for those with problems caused by being created haphazardly.
