Tolor was a male Orion who lived in the 32nd century. He was the nephew of Osyraa, the leader of the Emerald Chain. When he was a child, Osyraa had Tolor's father killed for challenging her control of the mercantile exchanges. Afterward, she took Tolor in and eventually granted him a position running the salvage yard on Hunhau.
In 3189, Tolor was fooled by Commander Michael Burnham and Philippa Georgiou into allowing them entry to his facility. Under the guise of shopping for pre-2400 technology, they made contact with Cleveland Booker, who had been captured by the Emerald Chain, and arranged a mass escape of the slave laborers at the yard. Though Tolor apprehended Burnham and Georgiou, they overpowered him and he was forced to flee via his portable transporter.
