After decades of peace, harmony, and stagnation in the kingdom of Novelon, the ancient conflict between the heroic Knights of Novelmore and the rebellious Burnham Raiders is rekindled. Both sides seek to possess the magical armor Invincibus, which makes its wearer invincible. King John and his clever, enterprising son, Prince Arwynn, who resents his father's strict rules and prefers adventure, live in the great castle of Novelmore. Thanks to Arwynn's drive for change and the help of his friends Gwenn and Dario, the Knights of Novelmore are able to face the many challenges of the new era. They are protected from attacks by the Burnham Raiders by the mighty castle walls and can defend themselves with stones and ballistae with water arrows. The Burnham Raiders try to penetrate, but the Knights of Novelmore quickly close the castle gates, and the danger seems averted. After a short time, some intruders breach the wall and enter the castle. Who will win the battle? Playmobil's new knightly world surprises with creative weapons, advanced defense systems, and original characters. This Playmobil classic in a brilliant new design guarantees hours of fun. The large Novelmore castle is equipped with a mechanical castle gate with an integrated catapult, ballista, elevator, and stone drainage channel. A trapdoor lets intruders directly into the vault.
