" I am," said Tessa. "I am Theresa Gray, daughter of a Greater Demon and Elizabeth Gray, who was born Adele Starkweather, one of your kind. I was the wife of William Herondale, who was the head of the London Institute, and I was the mother of James and Lucie Herondale. Will and I raised our Shadowhunter children to protect by the Laws of the Clave and Covenant, and to keep to the Accords. "
