A planet in the Cabral sector chosen in 2370 as a new home for a village of Boraalans secretly rescued from their dying world by Nikolai Rozhenko.
Vacca VI is an uninhabited, habitable planet in the Cabral sector. It appears in the seventh-season Next Generation episode Homeward.
When the atmosphere of Boraal II begins to dissipate in 2370, Worf's foster brother Nikolai Rozhenko defies the Prime Directive and beams a village of Boraalans into a holodeck on the Enterprise-D that he has set up to mimic their caves. Faced with people who would die if he sent them back, Picard reluctantly searches for a world resembling their own.
Vacca VI is the best match. Worf and Nikolai lead the villagers on a staged journey through changing holodeck scenery, explaining away malfunctions as omens, until they are beamed unknowing to the surface. One of them, the chronicler Vorin, wanders out into the ship and takes his own life. Nikolai stays behind on the planet with Dobara, who is carrying his child.
