Dorium Maldovar

Dorium was a black marketeer in the 52nd century.

Biography
After hearing that she was in search of time travel, Dorium met with River Song in the Maldovarium bar to offer her a Vortex manipulator that was, according to him, "Fresh off the wrist of a handsome Time Agent". As payment Song offered him a Callisto Pulse which could disarm Micro-explosives from up to 20 feet. When he enquired as to what kind of micro-explosives the pulse could disarm, she responded by saying the kind that she had just put in his wine. He was then forced to give her the Vortex Manipulator.
