In Novelmore, the Knights of Novelmore and the rebellious Burnham Raiders face off against each other in the battle for the magical armor of Invincibus. Dario DaVanci, Novelmore's most brilliant inventor, has equipped the Knights with a new secret weapon: The Mobile Fortress. This special attack tower with side cannons and giant stone slingshot is entirely to the taste of General Marcus McGriffin.

As the leader of Novelmore's armed forces, General McGriffin is always looking for new weapons and the ideal strategy that will lead to victory in battle. At his side is the clever mechanic Bolt Nutcliff, who always knows how to repair and maintain DaVanci's inventions. It will be hard for the Burnham Raiders to stop these two knights. The playset includes the Novelmore characters General Marcus McGriffin and Bolt Nutcliff, as well as a Mobile Fortress. The catapult fortress is equipped with two lateral cannons with four projectiles, as well as a giant stone slingshot.
