Brookish Boon was a Sy Myrthian female who was born on Sy Myrth around 57 BBY. In 19 BBY, Boon was on the planet Coruscant and stood with a hooded individual at the foot of the steps leading into the Galaxies Opera House while it was showing a performance of the ballet Squid Lake. As the pair stood together, the Jedi Knight Anakin Skywalker rushed past while en route to meet with Supreme Chancellor Palpatine inside the building.
In 34 ABY, when Boon was 91 years old, their stolen identity profile came into the possession of the pirate Hondo Ohnaka, owner of Ohnaka Transport Solutions. Ohnaka used the profile to test several individuals who were looking to join a flight crew that the pirate was putting together for an upcoming heist. He sent Boon's profile, along with several others, to the prospective crew members' datapads, then quizzed them on details from the files.
Brookish Boon is briefly visible in Star Wars: Episode III Revenge of the Sith.
