Vulcana Regar is a city on Vulcan.
During the late 21st century or early 22nd century, Vulcana Regar was the site of the Ka'Tann Conference. One of the top negotiators at the conference was Ambassador V'Lar, one of the attendees was T'Pol, who was in her early schooling on Vulcan, and who had traveled "a great distance" to see the Ambassador. (ENT: "Fallen Hero")
Late-24th century Starfleet Academy hopeful, T'shanik, was from Vulcana Regar. (TNG: "Coming of Age")
- It is unclear whether Vulcana Regar is a planet, a colony, or otherwise. However, the Star Trek Encyclopedia (published prior to the filming of "Fallen Hero") indicates it is a city, which is somewhat supported by T'Pol's comments in that episode.
