Seven Salazar is the novel’s main character. She is 12 years old and has “tawny-brown skin and dark curls” (3). Seven is determined and brave, as demonstrated when she invokes the Clause of the Impossible Task, a bold decision that sets the story’s plot into motion. Another one of the character’s primary traits is her intelligence. Seven earns the “the best grades in her class” at the Goody Garlick Academy for Magic (216). Seven’s studious nature advances the plot because she uses her knowledge of magical plants, casts advanced spells, and brews complicated potions to facilitate the Witchlings’ search for the Nightbeast and the person controlling the monster. At times, Seven’s intelligence leads her to stubbornly insist that she knows best. For example, Valley considers Seven a “know-it-all” because she repeatedly causes problems for the Witchlings by disregarding Valley’s monster-hunting expertise. Although Seven sometimes gets into trouble because of her reluctance to listen to others, her determination, intelligence, and bravery serve her well on her adventures.

Seven functions as the novel’s protagonist and viewpoint character. When she is first introduced, she is narrowly focused on her plans for success, wary of Valley, and dismissive toward Thorn.
