Graham, a Moff within the Sith Empire during the Galactic War, was a Human male. He, together with Moff Dolus, received an invitation from Moff Valion Pyron in 3640 BBY to witness the Silencer being tested aboard the Harrower-class dreadnought named Doombringer. Upon Pyron's introduction of Lord Kallig as the individual who finalized the Silencer, Graham expressed his displeasure with Dark Council member Darth Thanaton. Prior to the test, Captain Joris of Darth Achelon's flagship Carnage asked for assistance, and Graham proposed the destruction of Achelon. Following the Silencer's successful demonstration, Graham pledged his support to Kallig.
