The Cryptics of the Spheres
Each sphere contains a peculiarity, a species that seemed to appear out of nowhere, and remain evolutionarily resistant, similar to the horseshoe crabs of Earth, yet more extreme. Even in their homespheres, they tend to be isolationists and Notoriously hard to find.
Within the First Sphere, resides a roughly reptilian species that has been recorded three times due to the sheer inhospitability of their home sphere. The first time, there was an odd set of green shapes in the recording, the second time showed some kind of lizard, and the third time showed that they're more turtle than lizard, but scientists decided to leave well enough alone and refer to them as the Kappa.
