List of unnamed Kraylor.
A Kraylor officer and his ship was trapped in the Void in 2377. When the USS Voyager was trapped there as well, it tried to start an alliance and this officer was one of several invited aboard.
The Doctor and Fantome passed him talking to someone about a PADD while walking in the corridor to the mess hall. He later would have returned to his ship when the Kraylor decided to leave the alliance with Bosaal. (VOY: "The Void")
A Kraylor engineer had a job at the Primary Energy Facility on Quarra in 2377. (VOY: "Workforce")
