Queen Rutela

Queen Rutela is a character from The Legend of Zelda: Twilight Princess. Her husband was King Zora (one of the many to hold this title). She also has a son, Prince Ralis. She ruled as queen of the Zora until she was executed in front of her own people as a message to those who may oppose Zant. She wears a pendant that resembles the Zora's Sapphire, as does her son. Interestingly, she is one of the few characters in the game to recognize Link in his wolf form.

Biography
After Link restores the source of water at Zora's Domain, the ghost of Queen Rutela appears before Link. She requests that he aid her son, Prince Ralis, and ensure his safety. Link finds the Zora prince in Telma's bar in Hyrule Castle Town; however, he has fallen ill. Telma takes Prince Ralis to Kakariko Village, where a healer by the name of Renado resides. Along the way, Link protects their caravan against enemy attacks.

Once at Kakariko Village, Ralis is taken safely to Renado, and Rutela appears before Link once more to thank him for rescuing her son. She then shows him the way to the hidden Zora tomb behind the graveyard, where Link finds the Zora Armor, a special suit of Zora-made armor, made out of zora scales, that allows him to breathe underwater, by extent allowing him to enter the Lakebed Temple. After recovering, Ralis explains that Queen Rutela also appeared to him, informing him about Link's appearance and deeds.

In the ending credits, Queen Rutela can be seen watching over her people and her son Ralis.

Theory
Some believe that Rutela may in fact be the Sage of Water during the events of Twilight Princess, as when Link meets the Ancient Sages atop the Arbiter's Grounds, only five are seen. They reveal to Link their failed attempt at executing Ganondorf, during which he killed the Sage of Water; in the present age, the crest depicting the Water Medallion is broken as a result of the sage's death. Rutela explains that she lost her life to Ganondorf's invasion of Hyrule, and so it is possible that she was, in fact, the Sage of Water. Evidence to the contrary is the fact that all of the other Ancient Sages seem to be Hylians.

Etymology
Her name is likely a reference to Princess Ruto from The Legend of Zelda: Ocarina of Time.
