Seven Swords

The Seven Swords were swords that were originally possessed by the Seven Lost Lords that Caspian and the crew of the Dawn Treader voyaged to find in The Voyage of the Dawn Treader. Each sword possessed magical properties and when all were placed on Aslan's Table at Ramandu's Island, the darkness emanating from Dark Island that was slowly overtaking the lands of Narnia would be lifted. It is never explained in the film why Aslan entrusted the protection of Narnia to Telmarine Lords. Peter Pevensie's sword, Rhindon, was also shown to have similar magical properties, though it was not one of the seven.
