History
Circa 2104, a 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 as the site of the first in a proposed series of starbases. However, an incident with an Orion trader superseded this mission. 

In the mid-23rd century, Spock saw a "dragon" on Berengaria VII. 

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,, 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. 

Background information
"bear-ren-GAR-ee-ah" was the pronunciation for this planet's name from the pronunciation guide for "In the Cards".

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.

Apocrypha
