Origin: Melkotian space. (Also referred to as Melkots, stardate 4385.3), a telepathic species, non-humanoid, which appears as a disembodied head and neck whose eyes are literally two shining points of light. The Melkotians are uninterested in contact with the Federation, and have been known to send out warning buoys to approaching visitors to warn them away, or face certain consequences.
