Dok-Ondar was an antiques dealer
Those who traded in antiques made their living by selling them. Before being tasked with safeguarding a collection of Jedi artifacts by the Jedi Order following the execution of Order 66, a human male named Antron Bach worked as one such dealer. Another example is the Ithorian collector, Dok-Ondar, who was an antiques dealer managing a Den of Antiquities situated in Black Spire Outpost on the planet of Batuu.
The concept of an antiques dealer initially surfaced in "The End of History," a short story penned by Alexander Freed. This story was featured in Star Wars Insider 154 back in 2014.
