Hello again! This is Michelle of the Remus-variety, bringing in my second kid. This is James Carstairs, better known simply as "Jem". He is from the world of The Mortal Instruments/The Infernal Devices, and he's got a crazy kind of past.
Jem is a Shadowhunter, which is basically a fancy word for demon-slayer. He is of the blood the Angel Raziel, which allows him to mark his body with runes that enhance his skills and abilities. He is also a kick ass fighter, especially with his blade that he keeps concealed within his cane. So... why does a 17-year-old with badass reflexes and the job of a superhero carry a cane? Well, as a young boy, a demon tortured and killed his parents. It also tortured him by force-feeding him Yin Fen, a drug that is toxic to Shadownhunters. He was forced to take so much of it that his body now requires it in order for him to survive. Going too long without it results in terrible coughing fits. What's worse is that the drug is slowly killing him, and there is no cure.... yet.
Personality wise, Jem is very proper and a true gentleman. Being from the 1800s does have its perks. He comes from the Steampunk age, so to speak, and having lived for many years with Henry, he's likely to get used to all the technology floating around these days. Despite being very quiet, he is incredibly friendly and always willing to help no matter how much it may hurt him in the end. He is someone you can depend on, though you might feel bad leaning on him when he starts coughing. Will is his parabatai, and he is very close to him.
And... oh yeah! He loves Tessa. (:
Please throw plot my way! I would love for Jem to get involved with things right away.
