Tessa Gray



Theresa "Tessa" Gray is the Warlock daughter of Elizabeth Gray (Adele Starkweather) and a Greater Demon, the adoptive niece of Harriet Moore, the adoptive cousin cousin of Nate Gray, the widow of Will Herondale, the wife of Jem Carstairs and the main protagonist of The Infernal Devices book series. Unlike other children born to Shadowhunters and Demons who usually stillborn, Tessa survived because her mother was an unmarked Shadowhunter and had wore a Clockwork Angel pendant (which contained part of the soul of an angel called Iuriel) which Tessa later wore.
