Berengaria VII

From Memory Alpha, the free Star Trek reference.

Berengaria VII is a major planet in the United Federation of Planets, located in the Berengaria system. (TNG: "Conspiracy")

In December 2154, prior to the founding of the Federation, Berengaria VII was to be scouted by the Earth Starfleet ship Enterprise as the site of one of a proposed chain of starbases. T'Pol described the world as having a thriving ecosystem devoid of intelligent life. However, she mentioned that a Vulcan survey team had made note of a species of flying reptiles, over 200 meters in length, that breathe fire. However, an incident with the Orions postponed or canceled this mission. (ENT: "Bound")

At some point prior to 2267, Spock encountered a dragon-like creature on the planet, confirming the original story. (TOS: "This Side of Paradise")

In 2373, Kai Winn Adami asked Captain Benjamin Sisko rhetorically whether the Federation would sacrifice Berengaria to protect Bajor from the Dominion. (DS9: "In the Cards")

This would seem to indicate that Berengaria VII had become an important Federation colony world.

[edit] Background Information

Berengaria VII was mentioned as a small note on a very large star chart graphic created for TNG: "Conspiracy". It was the image behind the chair in the room where Dexter Remmick was killed. It appears to be near the Tholian Assembly, Gamma Canaris N, and Janus VI.

The non-canon reference work, the Star Trek: Star Charts, suggests that Berengaria is in the vicinity of a black cluster, Deep Space 3 and Starbase 514.
