Dario Brighton is a Hogwarts professor with a strong proclivity for nitid things. He can mostly be found roaming around the halls of the castle in search of things to get him distracted. During evening hours, he is most likely in his office on the sixth floor plotting castle blueprints for possible renovation schemes. Prof. Brighton claims the classroom just by the Transfiguration Courtyard. The annoyance he is currently facing is the distance between what he thinks is the best office in the castle and his classroom, which is making him petition the school board to approve his plans for more hidden passageways and an internal floo-network.
His field of expertise is Transfiguration, which he teaches during the morning hours. His students would probably define him as a bit demanding and on the stricter side, as he puts up high expectations from day one. Despite the sternness, he pours a lot of time and patience into his classes and is very protective of his students. He specialises in conjuration and vanishment. Though he also likes to dabble in duelling, especially dealing with defensive enchantments. He has never found his talents to involve potion-making, divination or herbology as he likes to face magic hands-on.
Because of his mastery of defensive enchantments, he was appointed Keeper of Grounds and Keys. He can be heard from a mile's distance walking across the hallways dangling a heavy key set in his left hand.
It is likely you've already heard of the formal dinner parties he hosts on Fridays, displaying the newest and finest sets of china he's managed to collect, making way too many analogies trying to explain the tiniest mechanics of Transfiguration and talking about his newest knitting project to his guests.
