Henry Branwell

Henry Branwell is absent-minded and brilliant. Henry spends his waking hours in the crypt of the Institute, inventing fabulous machines and weapons out of cogs, cams and gears. Unfortunately just as many of Henry's inventions do not work as the ones that do, and Henry is as likely to set himself on fire as he is to invent something new and amazing. Henry invented the portal with the help of the warlock, Magnus Bane.
Henry becomes crippled after a demonic automaton attacks and almost kills him. This causes Henry to become paraplegic, and he then has to use a wheelchair. At the end of the series, Henry takes Charlotte's maiden name, Fairchild, and they have two sons together, Charles and Matthew Fairchild.
