At a "magical school for knights in training" in the kingdom of Astoria, two very different students, Arc and Ciara, form a pact to keep each other's secrets and to follow their dreams of knighthood. Arc and Ciara train with their classmates Prudence and Warwick as well as their rivals Sage and Buttercup so that they would one day be knights and defend Astoria from various threats like its ex-king Ryker and his army.
