Nauian

Nauians were native species of Pollux V. Ages ago, they feared that their planet would go through an ice age and they retreated underground. They constructed a sonambutron which would re-activate them again in the next solar eclipse, however they would not predict that in the meantime the planet's moon would be destroyed. For the remaining millennia they remained in slumber and their security system would be active harassing the colonists that would settle the planet.
