Berengaria VII (also known as Berengaria) was the inhabited seventh planet of the Berengarius system. Classified as M Class, this Federation planet had no indigenous intelligent life, but possessed a flourishing ecosystem including a species of dragon-like flying reptiles.
In 2293, the location of Berengaria VII in the Milky Way Galaxy was labeled in the star chart "The Explored Galaxy", which was on display in Captain James T. Kirk's quarters aboard the USS Enterprise-A. (Star Trek VI: The Undiscovered Country, okudagram)
Circa 2104, a Vulcan science vessel surveyed Berengaria VII, describing its dragon-like creatures as over two hundred meters in length and breathing fire. In December 2154, Berengaria VII was to be scouted by the Starfleet ship Enterprise NX-01 as the site of the first in a proposed series of starbases. However, an incident with an Orion trader postponed or canceled this mission. (ENT: "Bound")
As of late 2373, on the eve of the Dominion War, Berengaria's strategic importance for the Federation was on par with worlds like Andor, Vulcan, and Earth. Kai Winn rhetorically asked Captain Benjamin Sisko whether he would promise to sacrifice those strategic planets in order to protect Bajor from the Jem'Hadar. (DS9: "In the Cards")
"bear-fen-GAR-ee-ah" was the pronunciation for this planet's name from the script pronunciation guide for "In the Cards".
According to the Star Trek: Star Charts ("United Federation of Planets I") and the Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), Berengaria was located in the Alpha Quadrant. In 2378, Berengaria VII was listed as a Federation member.
According to the The Worlds of the Federation, Berengaria VII had three moons, simply called "Alpha", "Beta" and "Gamma", and orbited a red giant star. It eventually became a Federation colony world, and subsequently a member world in its own right.(citation needed • edit)
The Pocket ENT novel Beneath the Raptor's Wing had this planet as the site of a starbase and it was fought over twice by the Coalition of Planets and the Romulans during the first year of the Earth-Romulan War.
Elias Vaughn, the new first officer of Deep Space 9 who first appeared in Avatar, was established to have been born on Berengaria VII in Twilight. In Fragments and Omens in Worlds of Star Trek: Deep Space Nine, Volume 2, the dragon-like reptile indigenous to the planet was called Draco Berengarius. The same novel also mentioned that Vaughn was once attacked by one. The TNG novel Losing the Peace mentioned a failed Borg attack on Berengaria in 2381.
