A Link to the Past features two separate but similar overworlds: the Light World and the Dark World. Link starts in the Light World, but by traveling through portals, he can enter the Dark World, a parallel version of the Light World. The Dark World has different enemies, non-playable characters, and dungeons, and the player will often have to travel back and forth between the two worlds to progress. The Dark World's locations and geography often line up with the Light World's, such as Kakariko Village and Thieves Town. While Link can enter the Dark World via portals, he can only exit the Dark World using an item called the Magic Mirror. This leaves a special portal behind that allows him to return through it, though it is erased if Link uses the Magic Mirror in the Dark World. At times, this allows Link to reach areas otherwise inaccessible.
