Stephen William Herondale was a Shadowhunter, who lived in Idris. He was a member of Valentine's Circle. He is the father of Jace and the son of Imogen and Marcus Herondale. He was also at one point married to Amatis Graymark, Luke's sister.
When Lucian Graymark, Stephen's brother-in-law, became a werewolf and Valentine needed a new second in command, Valentine chose Stephen and convinced him to divorce Amatis, the sister of Lucian, and marry Celine Herondale instead.
He was killed in the Circle's raid on a vampire nest. His mother, Imogen Herondale, accepted the position as Inquisitor to hunt down all those responsible for his death. His wife, Celine, also apparently killed herself by slitting her wrists when she heard of his death. Valentine, with the help of Hodge Starkweather, saved the baby Jace from his mother's womb as Jace was the baby that Valentine had been experimenting on with angel's blood.
Before his death, he wrote a letter to his son, believing that Valentine would kill him.
The Mortal InstrumentsEdit
Amatis tells Jace he looks exactly like Stephen, except he has his mother's eyes and gives him a box of Stephen's old things, including his letters to Amatis at the end of City of Glass.
