–Diana about choices, and choosing to be their tutor, Lady Midnight
Diana Wrayburn is a Shadowhunter who used to run a weapons shop called Diana's Arrow in Alicante. After the Dark War, Diana volunteered to be stationed at Los Angeles to become the tutor of the Blackthorn children.
When she was young, Diana had a mentor who shaped her personality.
Diana spent many years in Thailand and traveling Southeast Asia, either to fight demons or simply to travel, visiting Angkor Wat and other historical sites. At one point, she went to Thailand and stayed there for a year, during which both her brother, who was also in Thailand, and her father died, making her the last of the Wrayburns. After the Uprising, Diana inherited her father's weapons shop on Flintlock Street in Alicante.
Diana participated actively during the Clave meetings in Idris. Diana was appalled at the thought of losing Shadowhunters who had become Endarkened. The following day, Clary Fairchild and Jace Herondale came to her shop in search of a new sword. Diana decided to give Clary Heosphoros, the Morgenstern blade no one has even considered buying ever since it was sold to them by Jocelyn.
During the battle, Diana tried to come to the aid of the Blackthorn children but was too late, having witnessed Julian Blackthorn's need to kill his own father. Both concerned for and impressed by their resilience, Diana offered to take Katerina's place as the children's tutor at the Los Angeles Institute, an offer which Consul Penhallow considered.
Reminiscent of her own mentor, Diana wished to help Emma and the Blackthorns in the same way her mentor helped her. Despite her responsibility, she refused to become the head of the Los Angeles Institute, despite knowing that Arthur Blackthorn was not a capable leader.
In August 2012, Emma and the Institute visitor Cristina Rosales found a corpse related to a series of murders around the city, covered in the same markings as the corpses of Emma's parents from five years prior. Though the pair kept their own little investigation a secret from Diana and Arthur, they called Diana and the Silent Brothers upon finding it. Diana worried about Emma's feelings, knowing how much the case meant to her and being one of the few people who believed her theory that her parents weren't killed by Sebastian. With the Silent Brothers prohibiting Emma and Cristina from interfering with their own study of the corpse, Diana promised to tell her if she learns anything.
While she gave a lesson at the Institute one morning, a faerie convoy arrived, bringing with them Mark Blackthorn, who was taken from the family during the last war. Diana stayed outside the Sanctuary during the meeting, eavesdropping into the discussion, but entered to help mediate when Arthur's status came at risk of discovery. She kept the secret from the Clave and tried to help the children investigate, though she was unable to directly help and remained fairly absent, as she was away on secret trips.
Unbeknownst to the others, Diana was also conducting her own investigation. When she realized from the poem that it was about the Blackthorns, she approached Catarina Loss about the circumstances and soon discovered that the Guardian was their trusted warlock friend Malcolm Fade. She went to the convergence site—the base of Malcolm's necromantic activies—without telling the children to confront Malcolm herself but was met with the children anyway as they had caught onto Malcolm's secret, as well, and were there to rescue a captive Tavvy. She was briefly suspected by the children when she first arrived at the scene robed, before Malcolm arrived. She tried to get the children to run, to no avail, and was bound with magic when she tried to fight Malcolm.
Diana was eventually released from the spell. After the battle, and after Malcolm's death in Emma's hands, Diana was able to safely escape the cave with everyone. Diana offered to take the blame for them, for Julian's actions and their decision to keep the investigation from the Clave, but Julian refused, telling her that it was because she was a bad liar. As a measure to make it seem that she had little to no involvement, she immediately left after dropping off Cristina and Diego Rosales at the Institute.
Diana has black hair and dark skin. Her eyes are brown, with flecks of green in them. On her cheek is a tattoo of a silver koi fish. When Diana first came to the Los Angeles Institute as the children's tutor, Emma thought she was "the most beautiful woman [she'd] ever seen."
