Sebastian Verlac was a Shadowhunter and a cousin of Aline Penhallow. He was raised by his aunt Elodie Verlac who has been running the Institute of Paris since his parents' death. Some time in 2007, he was killed by Jonathan Christopher Morgenstern so he could take over his identity.
History
Around 2007, seventeen-year-old Sebastian was on his way to Idris to represent the Paris Institute at the emergency Council meeting about Valentine Morgenstern. He was sitting at a bar in a club in France when he was approached by Jonathan Morgenstern. Initially skeptical, Sebastian relaxed in the boy's presence when he learned that he was another Shadowhunter. The white-haired boy convincingly introduced himself as Andrew Blackthorn of the Los Angeles Institute who will be visiting Alicante for pleasure.
They then decided to hunt and kill the Eluthied demon rumored to have been lurking around the place. Jonathan soon spotted the demon in the shape of a girl. The pair followed the demon to an alley outside the club. After witnessing Jonathan viciously kill the demon, Sebastian was impressed, not afraid as Jonathan had expected. When Jonathan told him that he needed to leave, Sebastian was disappointed. Jonathan then proceeded to slit his throat, leaving a look of surprise on the boy's face. Jonathan, not wanting his body to be discovered, dumped Sebastian into a river close by. Jonathan thought he may have seen Sebastian's fingers bob in the current before sinking. Jonathan then went to the hotel Sebastian was staying to retrieve his belongings and soon dyed his hair to completely mimic him.
Tricking Sebastian and taking his identity was easy for Jonathan; not only had Sebastian not seen another Shadowhunter in a long time, but even his relatives in Alicante are no longer familiar with him, making him welcome at the Penhallows'.
Physical description
When Clary Fray was shown a picture of him by his cousin Aline Penhallow, she described him as handsome in an off-kilter sort of way. He was said to have a large nose, black hair, and a crooked grin. She also stated that Sebastian seemed to have been a good person to have fun with.
Jonathan also described Sebastian as tall, about the same height as him, and had the same slender build. His eyes were black, and his features, though irregular, came together pleasingly: he had a friendly charisma that was attractive. He looked like it was easy for him to trust, easy to smile.
