From UFStarfleet Wiki
The aliens known as Naasirkhans, under influence of the Spouwwqna, came to Astraios Prime to determine whether Astraios Colony was too heavily defended for a small scale invasion. While investigating a cave complex in the far far north of of the class M planet, the aliens found traces of an ancient race. The Kiqvarr relics, over 900 years old, had no importance for them, and some were therefore destroyed or mishandled. When supplies began to run out the Naasirkhan team decided to abandon the caves. They lost a couple of comrades due to a cave-in, and the remaining few Naasirkha left Astraios. Two specialists were then captured in the 116 system, and brought to SS Astraios. Thus First Contact between Starfleet and Naasirkhans occurred on stardate 130519.
On 130526 the two aliens escaped and through a series of events Captain Poison Toocool and her crew were able to establish the Naasirkhans were not acting as normal and were under the mind and body control of the Spouwwqna race. Eventually Starfleet was able to help free the Naasirkhans from the Spouwwqna, but not before the crew of the USS Neil Armstrong were captured by the Naasirkhan/Spouwwqna, tortured and subjected to medical experiments. About half the crew died before being rescued by the USS Argonaut.
The USS Neil Armstrong was eventually able to develop technology to repel the Spouwwqna, and to make them visible. At that point they discovered they could trap the entities and destroy them. They captured several and destroyed them, leaving one prisoner, who begged to go home to the Taakar Nebula to die, claiming it was the last of its species. The Armstrong did this, despite the violence perpetrated by the Spouwwqna on its crew.
