Pepper is a young orphan witch disciple at Chaosah, the smallest of the six schools of magic on the magical planet Hereva. She is aided by her cat Carrot, and lives with her mentors Thyme, Cayenne, and Cumin in a house in the forest of Squirrel's End. Her peers are Saffron, Shichimi, Coriander, and Camomile.

Humans and various humanoids live alongside dragons and other mystical animals. After years of war between the schools of magic, there is a grudging peace. Pepper navigates the vicissitudes of growing up in a changing world and works hard to find her own place in it, but does so with a sense of humor. But there are happenings between the nations elsewhere in Hereva that may put a wrench in her plans.
