In "The Lord of the Rings", the Fellowship of the Ring are on a quest to Mount Doom to destroy the One Ring made by the Dark Lord Sauron. During their journey, they face two evil choices to cross the Misty Mountains: over the mountain of Caradhras through the Redhorn Gate pass, or through Moria, a dark labyrinth of tunnels and pits. They first try the mountain pass, but the weather proves too severe, and the Fellowship turn back and approach Moria's West Gate, beside which the Watcher lived in a lake.
