Moon Gate

A Moon Gate is a portal between the Dark World and Hyrule in Four Swords and. Some Moon Gates are activated by default, but most need a Moon Pearl to operate. Moon Gates are often hidden beneath grass patches, dungeon flooring, or even under blocks of sidewalk; an area that yields a Moon Gate will twinkle when Link is nearby, emitting an audible shimmering sound as well, further distinguishing it from the surrounding landscape. When holding a Moon Pearl near a hidden Moon Gate, the Pearl will shatter and the Gate will reveal itself. The first Moon Gate appears in the Village of the Blue Maiden, and its constant incorporation into puzzles and battles becomes a staple throughout the rest of Link's journey, encountering them as far into Link's voyage as the final stage, the Realm of the Heavens.

During Dark Link battles, the Dark Link clones often switch between the Dark World and Hyrule via these Moon Gates, which operate to separate the two battlegrounds where Dark Link can be fought. However, though common during Dark Link battles and in Hyrule's overworld, in the side-scrolling stages such as the Tower of Winds, Moon Gates do not exist. In the same vein, outside of Four Swords and, Moon Gates are nowhere to be found, but have properties that exist in similar contemporary objects such as the Mirror of Twilight in , a vessel that can also transport Link to a netherworld.
