These aliens are the crews that were built by the Xeno-176. They are lithiovoric and known to be non combatants peaceful and calm. Infact those speices that know them and have run into them have never heard of one attacking. They will react in self defence amd usually destroy the attack not through superior tatics or strategy but through better technology. Most people consider them to be like dogs or other animals. Left alone or treated in a non hostile manner they leave well enough alone.
