Rancor keeper

Rancor keeper was a beastmaster profession related specifically to someone tasked with the the exhaustive upbringing, training, and care of a semi-sentient reptilian rancor. Commonly employed by members of the Hutt Clan, these skilled keepers would develop strong bonds with their rancors, oftentimes from a young age. Rancors raised by keepers were considered easier to contain and control, harkening back to their original domestication and bonds with the Witches of Dathomir.

Some time prior to 0 BBY, the Human slave Malakili became a beastmaster and rancor keeper for Jabba the Hutt's criminal empire, taking care of Jabba's pet rancor Pateesa under the Hutt's palace on Tatooine until Luke Skywalker killed Pateesa in 4 ABY.

In 9 ABY, the Ugnaught Hunter Dizzy, one half of Team Slingshot, owned a rancor keeper costume that he could don for the Hunters of the Outer Rim competition on Vespaara. That same year, a rancor and its keeper were gifted to the newly established Daimyo Boba Fett by the Hutts known as the Twins.
