Unity's Planet

The planet Unity has entirely assimilated, and plans to use to assimilate the Galactic Federation. It's native inhabitants appear to be a race of blue humanoids with three yellow-tipped protrusions on their heads. In the absence of Unity's control, the inhabitants quickly devolve into starting a race-war between those of them who have flat concentric ring nipples, and those who have cone nipples. The unassimilated crew of the S.S. Independence do not exhibit this, but they may have all been of a similar nipple-type.
