A violent aggressive race that may have some descendants in the various species of Ant that live on Earth. They were attacking the Mercora for inhabiting Earth, which they believed to be theirs and theirs alone.
It is known that they possessed nuclear fission devices and interstellar space vessels. In general, Nesk technology would be considered quite primitve for a spacefairing race by galactic standards today, but they were formidable in their time. However, it believed the Capasins later wiped out their space colonies when they attacked the Capasins. Scientists and archaeologists continue to look for evidence to support this theory.
