Marvid Qreph was a Columi industrialist and criminal who worked in tandem with his brother, Craitheus, for several decades. When they were younger, their mother was shot and put into a coma by an unknown would-be assassin, which prompted the brothers to track down and find their mother's failed killer. Their attempts had resulted in not only the deaths of several beings they blamed for their mother's condition, but also in the total destruction of everything that their victims held near and dear. During all this, Marvid and Craitheus used their super-genius intellects to create and grow a criminal empire that controlled several different industries throughout the galaxy.
