Wor Feighn was the name of a deceased Acamarian. The body of the deceased was recovered from Magab Lake. Although homicide was considered initially, an autopsy performed on the deceased person's body revealed the cause of death to be accidental drowning. At the time of the drowning, there were no other people in the area.
In 2366, this individual was mentioned in the death records archives, which were accessible to the crew of the USS Enterprise-D via the Acamarian planetary database (TNG: "The Vengeance Factor", okudagram)
This character was only mentioned in writing.
Wor Feighn seems to be named after John Whorfin, a character from The Adventures of Buckaroo Banzai Across the 8th Dimension. It was one of several in-joke references to the movie in the records.
