The Banea were a feathered humanoid species native to Banea in the Delta Quadrant. As of 2371, they were at war with the Numiri, with whom they originally shared a homeworld and whom they still considered neighbours.
A generally pleasant people, their legal system, based in courts and trials might result in severe punishment. At one point murder was punished with lethal injection. Later, murderers were forced to relive their victim's last moments periodically, by means of inserting the memory engrams of the victim into their brain. The Banea insisted that this was meant as punishment, not torture.
The medical technology that made this possible was considered beyond anything the Federation had encountered before.
There were several Numiri spies among the Banean people. In 2371, one of these spies framed Tom Paris of the USS Voyager for the murder of the prominent Banean weapons expert Tolen Ren, after a dalliance with his wife Lidell Ren.
The Banean heart was located through the intercostal space between their eighth and ninth right ribs. They had distinctive forehead ridges similar to the combs of some species of Earth birds, and feather-like structures around their faces and on their brows. (VOY: "Ex Post Facto")
