Imotru (Preserve)

The Imotru are an extinct sentient species. The Imotru lived in the towering cities they built on the plains. The Imotru were human-sized members of the Colony, possessing a hive mind but no apparent technology. They built their castle-like buildings out of the natural elements found on their homeworld, and formed them - mound upon mound - to create a complex series of living, eating, and egg-laying grottoes. They apparently decorated their rooms with brilliant, complex mosaics of stones and pebbles which appeared to be little more than splashes of color, until one stepped back and admired the entire wall from a distance
