Selene the Weaver

Selene the Weaver
Operating in the shadowy corners of Kigum's lower wards, Selene is known as a "Weaver"—a slang term for an illegal spell-modder. She takes standard magical scrolls and alters their arcane structure to produce unexpected, highly potent, and occasionally lethal results.
Operations
Selene's clientele consists of mercenaries, desperate adventurers, and underworld enforcers who need an edge and don't care about the risks. Her modified scrolls are infamous; a fireball scroll bought from Selene might detonate with twice the normal radius, but it also has a chance of exploding immediately upon reading.
Personality
Selene is pragmatic, cynical, and highly intelligent. She views magic not as a sacred art, but as a system to be hacked and optimized. She takes immense pride in her "weaves," treating each dangerously modified scroll as a unique work of art.
Interaction
Characters seeking immense but risky magical power might seek out Selene. She is also a target for the city's arcane enforcers, who view her modifications as a severe threat to public safety.
