Dark World

The Dark World is an evil paralleled version of the kingdom of Hyrule which was the result of Ganon's one wish granted by the Triforce. In the Dark World, Ganon reigns over all and his minions run rampant. Ganon felt that he was tricked by the Gods with the creation of the Dark World and seeks to merge it with the Light World in order to create true chaos. The Dark World was introduced in A Link to the Past, and contained eight full dungeons and many side quests and collectibles. Many monuments and landmarks present in the Light World were drastically transformed with the creation of the Dark World. Deserts became swamps, green fields became dead wastelands, Kakariko Village became a haven for thieves, as well as many others.

Link is able to travel from the Dark World to the Light World using the Magic Mirror. Upon using the mirror, Link creates a small portal in the Light World precisely where he was standing previously, which can be used to travel back into the Dark World. This technique was used to manufacture several puzzles that span across both worlds in order to successfully complete them. Some places in the Light World cannot be accessed unless traveling from the Dark World with the Magic Mirror.
