Mx. Herriot presents themself as a psychic and runs a small occult shop in the commercial district of Newfaire. Despite their calm, wise persona Diti is nothing more than a scam artist. They spent their childhood watching their parents fall into cults and MLMs and learned the trade from those who took advantage of their family. When their cousin approached them and explained real magik existed, Diti was curious to see if they could scam real mages as well. Candela Obscura, a secret society of paranormal investigators, accepted Diti's membership. They aren't sure whether they've successfully fooled the real thing or were simply accepted as a mundane person who could handle the occult regardless.

Diti utilizes their skill in deceit and subtlety to sneak their compatriots into places they shouldn't be. They tend to attribute any success to having "had a premonition" about the future. Has a wrist brace on their right arm.
