The Lion's Door was a natural rift that once connected the worlds of Eamon and Narnia. Discovered in the late 1130s in Marewood Forest, the first explorers to traverse it spent days on their expedition but returned mere hours after they left, revealing that time passed far faster on Narnia than on Eamon.
The Guild of Free Adventurers erected a vertical stone ring around the rift in 1140 to mark its location. On the Narnian side the rift stood against a low hill hidden in the forest just south of Glasswater, not far from the sea. Over the next 25 Eamon years, several groups of Narnian explorers and traders (including humans, fauns, and talking animals) were known to have ventured through the rift, bringing news of their world, their culture, and their deities with them.
When Narnia was unmade in 1165, the rift dissipated and the empty stone ring now stands as a monument to the lost world. The few Narnian emigrants living on Eamon treat the site with reverence and melancholy devotion.
The rift's name refers to the Narnian god Aslan.
