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, and endured at least until the end of The Golden Age of Narnia.
