Zora's Domain is a region of Hyrule featured often in The Legend of Zelda series. This watery land is the home of the aquatic Zora race. The land's pure water flows down to Lake Hylia.
In The Legend of Zelda: Ocarina of Time, the secluded Domain is hidden behind a waterfall in north eastern Hyrule. Link can access it when he plays Zelda's Lullaby at the waterfall. As a child, he first meets King Zora and discovers the plight of Princess Ruto being trapped in the cursed Lord Jabu Jabu's belly. If he wishes to obtain the Zora Sapphire to continue on his quest, he must rescue Ruto. As an adult, he finds Zora's Domain completely frozen over and Lake Hylia drained by the evil magic of Ganondorf. He must restore the balance by defeating the beast Morpha in the Water Temple.
In The Legend of Zelda: Twilight Princess, Zora's Domain is located in the Lanayru Province. It was ruled over by the late Queen Rutela and then her son Prince Ralis. When Link first comes across the Domain, it is again frozen with the Zora stuck in the ice. Link and Midna thaw the icy land and reanimate the Zora by teleporting in a large chunk of volcanic rock from Death Mountain. Snowpeak is also then accessible from the Domain.
