Christopher Lightwood is the second child and oldest son of Cecily Herondale and Gabriel Lightwood.


Early life

Christopher Lightwood was born in 1887, after his older sister, Anna, and before his younger brother, Alexander.

Christopher was mentored by fellow inventor Henry Branwell—also an old family friend of his parents and relatives. Though he was eccentric, their familiarity with Henry and his attitude made them able to adapt to him, and thus most of his family and friends were supportive of his experiments.[1]


Attending the Shadowhunter Academy at twelve in 1899, Christopher was accompanied by his cousin Thomas Lightwood and later by their family friend Matthew Fairchild. When his other cousin James Herondale arrived, their group tried to assimilate him into their group, though James kept distancing himself at first. Eventually, after James and Matthew resolved their issues, the four boys became good friends. Christopher was mostly oblivious to why the other students bullied or feared James, not thinking James was strange. Christopher was also constantly distracted and impressed by odd things, bothering even their professor Ragnor Fell.

A few weeks into the school year, Matthew gave Christopher materials that he could use to build explosives. They left the slow-acting bomb in the Academy's south wing, which exploded minutes after.[2] Christopher was asked to leave the academy following the explosion, though that had not been Matthew's intent. As it turned out, Ragnor had threatened to leave the school forever if they allowed him to remain.[3]

After James and Matthew left the Academy to train instead at the London Institute, the four boys remained close friends and have since almost always been together as a group.[4]
