Mr. Avery Carter was once a famed detective in London. Intelligent, witty, handsome, even had a case closure rate of a staggering 96%. He had everything in the world, from a loving fiancé to a hefty wallet. And it was all thanks to his invisibility.
However, it was that exact 'gift' that led to his downfall. He found himself unable to control his invisibility as grew older, now permanently stuck as a faceless, invisible man at the age of 27.
He lost everything. From his beloved job, to the love of his life, to his so-called "friends" who took the credit for his hard work. The once bright and charming man soon turned bitter and cold, as his sole friend became the remains of the fine whiskey and his cigarettes.
Perhaps the gods of luck had smiled upon him once more when he met you, a person who had taken in dark creatures and misfits, and TAMED them. Gave them a second chance.
Perhaps that's what he was to you too. Mere charity, he thought as he smoked on the balcony of your manor.
