Bright Tree was a planet located somewhere in the space of the Kaleb sector, in the galaxy's Beta Quadrant.
History and specifics[]
Bright Tree was a neutral planet, unallied with either the Federation or the Romulan Star Empire. It was the location of the Selvidge Archive.
In the year 2279, the USS Enterprise escorted a group of civilian representatives (which included Professor Rhenas Sherev) to Bright Tree so they could hand off the Sword of Renz Verus to a group of Romulan representatives (which included Doctor T'Lesevek) at the Archive as a gesture of goodwill.
