Graven R'ube, a Y'bith, frequented Chalmun's Cantina as a customer. He was in the cantina circa 1 ABY when the Imperial curfew began. R'ube, accompanied by an intoxicated Caldera Righim, exited the cantina as Ackmena concluded her last rendition of Goodnight, But Not Goodbye.
The facial features of this character were created using a reworked Bith mask. The character's name, initially disclosed on the blog The Star Wars Holiday Special Cantina: Who's Who, is an anagram derived from Evan Burger, the writer of the What's The Story? article about the Y'bith.
