The Brunali homeworld was the home planet of the Brunali. Located in the Delta Quadrant, this inhabited planet was situated less than a light year from a Borg transwarp conduit. As a result, starting in 2366 and lasting for a decade, the planet had been attacked on numerous occasions by the Borg.
In 2376, the USS Voyager visited the planet to return the rescued Borg drone Icheb to his home. However, they discovered that Icheb had been genetically altered for use as a weapon against the Borg, and that his parents intended to return him to that fate. (VOY: "Child's Play")
