B'nish
B'nish was a planetary body within the galaxy (as per Legends continuity). The Human female character First was once enslaved on this world before her liberation, which occurred circa 41.5 ABY. The B'nishi species originated from this planet.
Behind the scenes
Christie Golden's short story, "First Blood", included a brief reference to B'nish. The specific nature of B'nish was not clarified; it wasn't specified if it was a city, a planet, or another kind of place. Nevertheless, because the primary planet in "First Blood" is unnamed, it's plausible the story unfolds on B'nish, a fact substantiated as canonical in the 2011 novel Fate of the Jedi: Ascension and later in the 2012 novel Fate of the Jedi: Apocalypse.
