Endicor was a star system, located somewhere in the galaxy's Alpha or Beta Quadrants, in or near the 23rd century boundaries of Federation space.
History and specifics[]
Endicor's orbit was the location of a planetary system, including the world Endicor. (TOS comic: "Marriage of Inconvenience"; TNG episode: "Time Squared")
- Possibly a coincidence, the mention of a place called "Endicor" in the May 1989 TOS comic preceded the mention of Endicor in the canon episode, released in April 1989, by almost a full year. In general, Star Trek television and movie productions of that era tended to avoid referencing material from the comics and novels.
