Zelda's Mother

Zelda's Mother is a character mentioned in The Legend of Zelda: Breath of the Wild. She the mother Princess Zelda and wife of King Rhoam Bosphoramus Hyrule. She is also the first known Queen of Hyrule.

Biography
Very little is known about the Queen of Hyrule other than mention of her by her daughter and husband in their diaries found in Hyrule Castle. Like Tetra's Mother from The Wind Waker her name is never revealed and she is deceased by the time of game's events.

What is known is that she lived at least six years after the birth of her daughter as Zelda was six years old when her mother passed and that her death was sudden and unexpected, suggesting it was either by a sudden illness or accidental, as there is no indication her death was the result of fowl play.

Legacy
Her death had a profound effect on her husband who as a widower had to raise their daughter alone. While Zelda was saddened by her mother's death, she never cried or faltered not even during her mother's funeral or when she and her father grieved in private. Rhoam assumed Zelda's strength was the result of him and his wife repeatedly informing her of her duty to be a valiant and steady princess. However despite not showing it outwardly, Zelda was deeply sadden by her mother's death as she had not lost a mother but also her teacher and as a result Zelda struggled to awaken her sealing magic which all Princesses of Hyrule possess due to possessing the blood of the Goddess Hylia, though they must purify themselves and pray to Hylia at the Spring of Courage, Spring of Power, and Spring of Wisdom. Though she did not show it outwardly, Zelda began to hate herself for failing to awaken her powers despite being a Princess of Hyrule and began focus more on studying Ancient technology rather than pray. Due to the imminent threat of Calamity Ganon's return King Rhoam order his daughter to train relentlessly and insisted she fulfill her duty which strained their relationship, scolding Zelda when she put off training to study ancient technology. By the time King Rhoam realized he had been too hard on Zelda and planned to encourage her more, though unfortunately the Great Calamity occurred and King Rhoam died, leaving Zelda to deal with the threat of Calamity Ganon whom she would seal along with herself in Hyrule Castle for 100 years as she waited for Link to awaken so they could finally defeat and seal Ganon.

Former Princess of Hyrule
As she is said to be Zelda's mentor and her daughter struggled to awaken her powers despite years of self training, it is implied that the Queen of Hyrule possessed similar powers indicating that she may possess the blood of the Goddess and thus was a former Princess of Hyrule and presumably a descendant of Hylia's mortal incarnation from Skyward Sword. As the Princesses of Hyrule are traditionally named Zelda, this would mean she could have been a incarnation of Princess Zelda, which has occurred in other games as Tetra is the grandmother (ancestor in english localizations) of Princess Zelda from Spirit Tracks showing that incarnations of Zelda can be related to one another. Presumably she had already awakened her sealing powers and would have instructed and helped her daughter awaken hers where it not for her sudden death.
