The Bitthævrian people originated from the planet Guiteica, which was their homeworld. Historically, Kaleesh warlords often claimed roggwarts, creatures native to the Bitthævrian planet, as prized possessions or trophies.
Within the current Star Wars canon, the Bitthævrian's initial reference occurred within the sixty-fifth issue of the Star Wars: Build the Millennium Falcon magazine, released back in 2016. It is important to note that the Bitthævrian sentient species was initially presented within the Star Wars Legends continuity in Alliance Intelligence Reports, a sourcebook for West End Games' Star Wars: The Roleplaying Game, which was published in 1995.
