Alexander Lightwood is the third and youngest child of Gabriel and Cecily Lightwood.


Born in 1900, Alexander is the younger sibling of Anna and Christopher, born 13 years after the latter.[1] Like Anna, he inherited their mother's blue eyes.

When his cousin Barbara Lightwood died of demonic poison, his cousin, Lucie, and the ghost of Jessamine Lovelace kept him company while his parents conversed with Lucie's parents.

He was later at the Enclave meeting to discuss the incidents that had happened around the city. While waiting for the Consul to arrive, he amused himself by tossing shiny, valuable, breakable objects near the fountain in the Sanctuary.

He was then brought to his cousin James's engagement party. He was left with his cousin Thomas while his parents helped set up. When Thomas tried to pawn him off on Lucie, he began demanding Matthew and Oscar.[2]

In December 1903, he attended James and Cordelia's wedding ceremony. Despite the loud noises of celebration, he remarkably slept through the ceremony in the nursery and into part of the reception in his mother's arms. He later woke and was seen playing with his cousin Eugenia and Ariadne Bridgestock.

A few weeks later, when Cecily and Gabriel temporarily took control of the London Institute while Will and Tessa had gone to Paris, he and Christopher went with their parents and stayed there.

When Leviathan attacked, his mother rushed to his room to be by his side and provided light for those in battle. After the attack ceased, Cecily to him to visit Gabriel in the infirmary—as he had been injured during the fight—and they stayed the night with him at the Institute. During dinner, he played with Lucie, who allowed him to walk on the table and occasionally fed him biscuits.[3]
