Pattians are humanoid aliens that exist on the planet Pataitia. They are pretty much "enhanced humans" despite being a race developed entirely independent from Earth. The most noticeable differences anatomically is that their stomach and brain are swapped around compared to humans and their bones can be flexible or stiff depending on how energised they are. The entirety of the planet has been colonised and a standard language has been established. This language being porisan Telansjanze.
Not only are they similar to humans anatomically, but they are also quite similar to Western humans culturally, almost every aspect being the same. They are also much farther developed that humans, such as them discovering a way to peek into the 4th dimension when it was 1382A.D. back on Earth.
