Adora and Bow visit a school in Northland, to tell the children how Etheria was a peaceful place before the Horde invaded it and took over. One boy, Corey, accuses them of lying, believing that the Horde are a peaceful government and the planet's rightful rulers. Just then, Northland is invaded by the Horde themselves, who steal all the school's books for a book burning ceremony, with the intention of replacing them with books depicting the Horde as the rightful rulers of Etheria. Hordak also appoints Tung Lashor as a new teacher for the school. As books are burned in the town square, and the Horde do all they can to ensure the schools teach pro-Horde views, She-Ra must do all she can to stop them, before the Horde's propaganda can corrupt the minds of the children.
