Biography
Princess Hilda appears to be Princess Zelda's Lorulean counterpart. She wishes for her land to have a hero, and believes Link to be a suitable candidate. Hilda can communicate with Link telepathically. She acts as a guide while he traverses Lorule.

When Link chases after Yuga to Lorule, he finds himself in Lorule Castle, where Yuga surrounds himself with the Paintings of the Seven Sages, using their power to obtain the Triforce of Power and merge with Ganon. Hilda appears shortly thereafter to restrain him and allow Link to escape. She takes him to another dimension, where she explains that he must retrieve the Seven Sages who are now scattered across Lorule and join forces with them to defeat Yuga. She leaves him in a road near the Lorulean Blacksmith's house. After Link awakens, Hilda speaks to Link telepathically to explain the dichotomy between Hyrule and Lorule, and that Yuga's actions have caused Fissures to appear, linking both worlds. She also explains that because of the ruined state of Lorule, Link cannot access all parts of it from within her kingdom, so the young hero must enter Lorule from equivalent locations in Hyrule. Afterwards, Hilda acts as a guide, telepathically communicating with the young hero whenever he enters new parts of Lorule. When Link enters Lorule from the Sanctuary, she tells him that the Lorulean location was once a holy place, but has now become the opposite, and that something nearby will help him on his journey. When Link enters Lorule near Turtle Rock, she tells the young hero that there is a fiery maze nearby, and that he must find a way to control the flames to find the Sage within. Upon entering Lorule near the Dark Palace, Hilda tells Link that he has entered an evil place where former Lorulean soldiers have been corrupted and now worship a terrible beast, a fact which she laments over. When Link enters Lorule from Rosso's Ore Mine on Death Mountain, where she tells the young hero that the Lorulean Death Mountain is covered in a perpetual winter and that Rosso is trapped there. Upon entering near Misery Mire, Hilda tells Link that she senses the presence of a Sage in the desert, but remarks that Lorule does not have deserts. She tells the young hero that he must begin his search in the nearby Swamp.

Occasionally after Link saves a sage, Hilda is seen talking to Zelda's portrait in Lorule castle, commenting on how she hopes that their Hyrulian hero will succeed.

After Link rescues all seven of the sages, Hilda informs Link that Lorule once had its own Triforce. The Lorulians fought brutal wars over the Triforce, and in order to put a stop to the chaos Hilda's ancestors destroyed their Triforce utterly. It was done with good intentions, but it had disastrous consequences. Lorule was not able to exist without the Triforce's power, and began to tear itself apart. Hilda couldn't bear to see her beloved kingdom rent to pieces, slowly dying, so when she discovered of the existence of another Triforce (Hyrule's Triforce), she schemed to obtain it so she could restore Lorule and protect her people from destruction. With that, she swiftly steals Zelda's Triforce of Wisdom and summons Yuga-Ganon to take Link's Triforce of Courage by force.

After the battle is over and Zelda is revived, Hilda, at the end of her rope, asks "What can I do now?". Zelda tries to tell her she understands the burdens of being a princess and a leader, but Hilda snaps that she knows nothing. Suddenly Ravio intervenes and reveals himself to be Link's cowardly Lorulian counterpart. He tells his princess that he knew Yuga's and her plan to steal Hyrule's Triforce was a bad idea, but he was too scared to confront them on his own. So he journeyed to Hyrule in search of a hero who could stop them. At first Hilda is furious at his betrayal, but soon realizes that she is perpetuating the chaos that caused her Triforce's destruction. Horrified at herself, she apologizes to Link and Zelda and agrees to send them home. She and Ravio take them to what was once Lorule's Sacred Realm and use the last of Ravio's Bracelet's power to send them through a crack to Hyrule.

Link and the Princess re-enter their world in the Sacred Realm with their Triforce straight ahead. Zelda and Link look at each other, knowing they each have the same wish, and touch the Triforce together.

In Lorule, Hilda and Ravio have not moved. Suddenly an earthquake rocks them to the ground, startling them both. They watch in amazement as the Lorulean Triforce is remade above them, whole and intact once more. An overjoyed Ravio smiles hugely as Princess Hilda happily cries. Lorule's darkness is infused with light, and Hilda thanks Zelda and Link for gifting Lorule its rightful Triforce.

Trivia

 * Both the names Hilda and Zelda come from the same Germanic root element, "hild," meaning "battle."
 * Hilda is referred to as "Her Grace" by Yuga, the same title that the Goddess Hylia (the first Zelda and the ancestor of the rest) was also referred to as, foreshadowing that Hilda (Zelda's counterpart) is actually Yuga's master.
