Gordon Edgley, Valkyrie's uncle, was a wealthy author of horror fiction who based his bestselling novels on adventures he had had with Skulduggery Pleasant.
He and Stephanie's mother dated for a while until she met Gordon's brother, Desmond, who later became Stephanie's father. Gordon chivalrously stepped aside and allowed his girlfriend to marry his brother although he later complained that he had never had anything more than a peck on the cheek. He did however go on to have numerous torrid affairs with many beautiful women. But Gordon does seem to have a soft spot for China Sorrows as many seem to. His infatuation for her could have been magic or as Gordon likes to think "but my love was stronger and true" after Valkyrie pointed out "Everyone's in love with China." Gordon was even known to have some books that China had dreamed about. Gordon died whilst putting the finishing touches to his novel And the Darkness Rained Upon Them before being killed by Nefarian Serpine. Secretly he had The Sceptre of the Ancients concealed in a maze of catacombs beneath his mansion and left the Key to it (disguised as a brooch) to his greedy brother Fergus and his grasping wife Beryl. He left his fortune and mansion to Stephanie.
A living image or "ghost" of Gordon is seen in an Echo Stone in Playing With Fire. Stephanie found the stone in a secret room in Gordon's mansion and later took it to the family reunion with her in a pocket. When taking refuge from her disagreeable cousins in an adjourning room, Stephanie took the Echo-Stone out of her pocket and had a conversation with the living memory of Gordon. While being a separate entity from the real Gordon, the living memory in the Echo-Stone was essentially a perfect copy of the real Gordon. After learning that Gordon was dead, the "Echo-Gordon" had something of an existential crisis but did not lose his sense of humor, dryly remarking that being taken to the family reunion with Stephanie reminded him that he didn't miss his family at all. He told Valkyrie about The Torment, who knew about the Grotesquery. Gordon was once genuinely in love with China Sorrows and liked to think that she reciprocated his feelings. Gordon played a very small role in The Faceless Ones, though he does assist Valkyrie in finding a new crystal to power the Sceptre of the Ancients, and points her in the direction of Anathem Mire's house in the tunnels underneath his house. It is also revealed that Tanith Low is a fan of his books and that Valkyrie is hesitant to tell her about the Echo-Stone. In Mortal Coil, Gordon finally reveals himself so he can teach Fletcher how to teleport over 2000 Remnants. Over the course of the next few books, he offers advice and guidance to the others, most notably being Valkyrie herself. However, in The Dying of the Light, he is wiped out by Darquesse.
Skulduggery describes Gordon as "sharp-tongued, strong-willed, intelligent, doesn't suffer fools gladly" traits Stephanie herself possesses. Gordon was a cultured and sophisticated gentleman with a childish playful demeanor who had a great fondness for Stephanie although he didn't have children of his own. He is shown to have an incredible ego and at first, cannot bear Valkyrie wanting to tell others that he exists for fear that they would see him as diminished.
