Duchy of Lantern Waste

The Duchy of Lantern Waste was a heavily-wooded northwestern territory of the Kingdom of Narnia where many adventures of Earth-native humans began in the world of Narnia. It was the location of the wardrobe portal that linked Earth and Narnia as well as the community of Beaversdam. Lantern Waste got its name from a prominent lamp post in the area whose light never extinguished and which existed in Narnia since the world's creation. Lantern Waste became incorporated as a Narnian duchy as early as the reign of Frank I.

Creation
The lantern itself was created at the beginning of Narnia when Jadis threw a piece of a lamp post (from London) at Aslan, it fell onto the new Narnian soil, and it grew into a lamp post as a tree would grow from a sapling; it's light never goes out as the lamp post has become semi-organic.

Trivia

 * Caspian X was the last identified Duke of Lantern Waste.
 * Lantern Waste is the location of Mr. Tumnus's cave and he was on his way home with some parcels when he first met Lucy Pevensie there.
 * Lantern Waste was also the home of the Tree of Protection which was planted by Digory Kirke to keep Jadis out of Narnia after its creation. This was due to the music Aslan sang that made everything grow. The wood from the magical tree was later used to construct the wardrobe.
