The Carstairs family is an old Shadowhunter family.


In the 1800s, Jonah Carstairs, his wife Ke Wen Yu, and their son James lived in and ran the Shanghai Institute. When his parents were killed by the Greater Demon Yanluo, Jem was sent to the London Institute.[1]

After Jem became a Silent Brother, his uncle, Elias Carstairs, carried on the family name and the sword, Cortana, was passed down his line of the family.[2]

In 2007, after the death of her parents John and Cordelia Carstairs, Emma became the new owner of Cortana. Shortly after, Jem became mortal again after coming into contact with Jace Herondale's heavenly fire. Jem and Emma both played their parts in the war against Sebastian Morgenstern. After the war, Emma moved into the Los Angeles Institute to live with the Blackthorns, and Jem married his past fiancée, Tessa Gray.[3]

In 2012, Emma played a very important role in the fight against the Guardian and the Cohort.[4]
