Aygo

A domed city is the only civilization on Aygo. There, the invertebrate Zhmun live in opulent splendor, relying on the service of their slaves and the toil of offworlders in the zhmun-owned mining concerns on the system's gas giants. Some zhmun use hydrostatic pressure and the ability to alter the rigidity of their tissues to hold themselves in a roughly humanoid shape. Zhmun who can’t achieve consistent humanoid appearance are second-class citizens — "globs."
