Dahri

The Dahri were once slaves to the Tkon species. After the Tkon were nearly driven to extinction, they created their own empire using the inhabitants of the plants they conquered for mining and farming purposes. However, when their homeworld was destroyed, their hive consciousness was broken, leaving them in little pockets scattered across the galaxy. A group of devolved Dahri lived in caves on the Terran Federation colony of Terra Nova, where they fed off any human who walked in.
