Bandi
The Bandi are a humanoid race who inhabit the planet Deneb IV. Their technology is not particularly advanced, and their architecture is surprisingly simple.
During the mid-24th century, a group of Bandi captured an injured spaceborne entity and brought it to the surface of Deneb IV. The Bandi nourished the lifeform back to health, but kept it only strong enough to use its unique ability to change energy into matter. Too weak to leave the surface, the creature was imprisoned on the planet and forced to manifest itself as Farpoint Station.
In the year 2364, the lifeform's mate came to Deneb IV to free it, attacking the nearby "Old Bandi City". This attack lead the crew of the USS Enterprise-D to realize the nature of Farpoint Station and give aid to the injured creature, allowing it to rejoin its mate in orbit of Deneb.
