Vurian

The Vurian species were an alien race that lived in the galaxy.

Overview
They were white skinned and four armed species that resembled a humanoid roughly which had both male as well as female genders. A certain gas mixture was capable of knocking a Vurian out without harming it but required large quantities of it to be used for it to be effective.

History
Their species were believed to have been extinct by the 23rd century when they died out by the time Zefram Cochrane developed the warp drive. They were known to have been massacred in the Three Systems War. After their supposed extinction, it was noted that no one had seen a Vurian for a hundred and fifty years though knowledge of their biology was known to doctors. What was not known to many was that the last known Vurian, Emminata, attempted to escape from her attackers and slingshoted into the Antares Sector where she was lost in the Antares Rift and transported into a parallel universe. Once there, she was cared for and telepathically linked to the Savant.

In the 2260's, when the USS Enterprise was exploring the Antares Rift, the ship was disabled and boarded a Vurian who kidnapped science officer Spock under the command of the Savant. The Vurian Emminata had taken control of the Auxiliary Control Room on the vessel which prompted Captain James T. Kirk to attempt to knock it out by a gas mixture introduced into the ship the vents. However, when the crew arrived in the room once more, the Vurian seemingly teleported away and vanished inside a Rift where it was transported into another dimension.
