Nayru (Oracle)

The human Nayru is best known as the Oracle of Ages. Due to their identical names, and similar personalities and symbolism, it has been theorized that she is an incarnation of the goddess Nayru herself.

Oracle of Ages
Nayru first appears in the game, Oracle of Ages, which is, of course, named after her title. She is a singer with one of the finest voices ever heard in Labrynna. However, her true identity as the Oracle of Ages is exposed when Veran possesses her, in order to take control of Nayru's ability to control the flow of time.

Nayru is a very peaceful person. She enjoys singing, and it is this that has made her popular throughout the land, among humans and animals alike. She attracts both when she sings. Her personality is somewhat timid, but judging from her actions, she'll do whatever she can to help a friend in need, or Link. Ralph, her protector whom she has known since they were both children, is a close friend of hers, and never far away.

Nayru also possesses a mystical instrument known as the Harp of Ages, which allows Link (and presumably whoever holds it) to shift through the folds of time, when the right songs are played. However, Nayru will also use the Harp for simply playing a tune on occasion. As the Oracle of Ages, Nayru has no true need for the Harp of Ages, as she is capable of moving through time at a whim. It is quite likely that Nayru herself created the Harp of Ages.

Possessed Nayru
Although never named directly so in Oracle of Ages, Possessed Nayru is a fanon name given to Nayru while she is possessed by Veran. She was initially possessed in the opening scenes of the game, where the handful of witnesses included Impa, Ralph and Link. Everyone else, aside from the nearly-omniscient Maku Tree, is unaware of the possession, and still believe she is the pure Oracle of Ages. With Nayru serving as her cloak, Veran begins to malevolently advise Queen Ambi's decisions in the past, which affect both the past age's citizens, and the present age in which Link initially resides.

One notable influence Veran gave was to seal off Ambi's Palace from casual visitors, barring both Link and Ralph from attacking Veran directly. Another was to discreetly confiscate all Mystery Seeds, the only known way to harm a possessing Veran without also hurting the possessed. Early in the game, Link unknowingly offered his seeds to the Queen and her adviser in order to temporarily enter the Palace and meet Veran face-to-face. He was still able to gain more Mystery Seeds later in the game, however.

After obtaining the Lonely Peak, Queen Ambi leaves her Palace, dropping the guard enough for Link to penetrate the castle's defenses and reach Possessed Nayru. Once Link is victorious in the ensuing battle, Nayru will be freed from Veran's grasp, and teach Link the Tune of Ages. Veran herself will instead possess Queen Ambi, a possession that will remain until the significantly tougher final boss fight in Black Tower.

Strategy
Possessed Nayru's only attack consists of shooting fireballs in a radial pattern. The projectiles spread out the further they travel, and Link's shield can't block them, so it's best to walk in the gaps that form at a distance.

The only way to attack Veran herself is by shooting her with Mystery Seeds from Link's Seed Shooter, or simply sprinkling the seed on her. If hit, Veran will temporarily lose her possession, but she'll seep back into Nayru if Link is not fast enough. By switching places with her via the Long Hook, she'll have a tougher time getting back to the body, and Link will have the opportunity to slash her at least once. Even so, Possessed Nayru will often hide behind pillars scattered across the room while she prepares an attack, making it harder to hit her with the Seed Shooter and Long Hook fast enough to get an attack in. If the attack process is repeated three times, Veran will be temporarily defeated, and Naryu will be freed.

The Minish Cap
Nayru also appears in The Minish Cap, where it is mentioned that she descends from a long line of oracles in Labrynna. She is one of the three ladies in the Happy Hearth Inn (along with Din and Farore). In exchange for help finding a house, she will be able to give Link a charm. Nayru's charm boosts defense and turns Link's tunic blue for the short duration of the effect.

Trivia

 * Nayru's harp, the Harp of Ages, is one of the two harps that Link acquires in the Zelda series, the second being the Goddess's Harp in Skyward Sword.
