Darkness threatens the land. With an evil creature killing dragons and riders alike, the False King's reign of terror spills across the border. While the king of Osnen and the Citadel's riders struggle to stem the assault, Eldwin flies to the Conclave to plead for help from the other schools. Unless the schools unite and arrive in time, the world is doomed. Fans of Sarah K.L. Wilson's Dragon School, Christopher Paolini's Eragon and Anne McCaffrey's Dragon Riders of Pern will feel right at home. The Warrior's Call is the third episode of the series Dragon Riders of Osnen.
