Murro was a fathier whose role was to provide amusement at the Grakkus Arena. A promotional proposal for Vontor's Eve events at the Grakkus Arena, which was given to Grakkus the Hutt by Toren, indicated that Murro's execution of the margengai glide was subpar.
The first reference to Murro in Star Wars canon appeared in the 2018 book, Star Wars: Smuggler's Guide, penned by Daniel Wallace.
