Master of Saber of Black in the Great Holy Grail War, Gordes comes from the Musik house, which once boasted a skill with alchemy which rivaled the Einzberns. Their thaumaturgical blood had eventually decayed enough that they were forced to fold themselves into the ranks of Yggdmillennia. It was shameful for such a once-famed house to have been absorbed by another, so Gordes' mother and father constantly told him of their legacy as alchemists from his youth. At the age of thirty-six, he is unable to separate dream from reality, having been raised to be proud of his family's former legacy.

Gordes summons his Servant, Saber of Black, along with Fiore, Celenike, and Caules in a multiple summoning. He keeps his catalyst, a bloodstained leaf from a sacred fig tree obtained from connections with the Einzbern family, in a case due to its value and not wishing for others to see it due to its connection to his Servant. Though it was agreed that all would share the names of their Servants, he vehemently disagrees, claiming that he had not yet had his catalyst when he agreed to the promise. He claims that revealing knowledge of his Servant's true name to anyone but Darnic would be detrimental to their battle.

He only recognizes Saber as "simply a Servant", a temporary guest brought to the world by his Master, despite the tension. Saber consents with a nod, causing Gordes to recognize that he has bent his Servant to his will, creating a misunderstanding between the two that brought events to a fatal pass.
