The affairs of Quockra-4 seem to be populated and managed entirely by various types of alien droids. Many of the droids are Imperial manufacture, but some are of unknown design. Some of the Imperial models can speak with the visitors, but will not be able to tell them much about the world except that they really don't like it much. The other droids speak machine languages. In reality, the droids are merely the servants of the true masters of Quockra-4 - enormous black-skinned slug-like creatures which live deep underground.
At one time, when the world had more moisture, the Quockrans lived on the surface. Then the climate changed becoming hotter and drier, and the delicate-skinned beings were forced to move underground. They only emerge on the surface at night, when the air is cool and damp.
Naturally xenophobic, the Quockrans intensely dislike dealing with aliens. They are completely indifferent to the affairs of the galaxy, and will not, in any imaginable circumstances, get involved in alien politics (e.g., the Rebellion). Their most basic desire is to be left alone. It was this desire to avoid dealing with outsiders that moved the Quockrans to engineer an entire society of droids to liasion with other species. |
