Age of Shadow
From Zelda Legends Wiki
Veran hopes to create her age of shadow by spreading her influence throughout the past.
The Age of Shadow[s] (also known as the Age of Darkness) will cover the land of Labrynna in sorrow and complete darkness. Veran, Sorceress of Shadows, tries to get Labrynna in this state by going back into the past using Nayru's powers. In the past, she misuses Queen Ambi to finish the Black Tower for her own purposes. Finishing the tower will allow Veran to reach out for the heavens, and by doing so Veran can obtain the powers of darkness. When this happens, the land will be filled with sorrow in the past, which means the present will be infected as well.
Veran almost succeeds in doing so, but just in the nick of time Link is able to stop her evil ambitions once and for all. By defeating the Sorceress of Shadows he puts a halt to the Age of Shadow and makes sure it will never exist.
At the end of game it is revealed that creating the Age of Shadow was not Veran’s main objective. Even though Link took her down once and for all, she did succeed in igniting the Flame of Sorrow. This was one of the three flames needed to start the “Dark Rites” ritual to revive the evil king Ganon.
Veran, taking over Nayru's body (from the game):
"Now the oracle's powers are mine. I can travel through time as I choose! Now a new age shall begin..."
Veran, taking over Nayru's body (from the manual):
"Now the power of the Oracle of Ages is mine! I can travel through time at will! Now a new age shall begin--an age of shadows!"
Upon meeting the Maku Tree for the first time:
“Pleased to meet you, young hero. I am the Maku Tree, guardian of Labrynna. Veran, Sorceress of Shadows, has taken Nayru, the Oracle of Ages. She's disrupting the flow of time from the past. She's trying to flood this world with the power of sorrow. We cannot give in to one of impure heart. You must stop Veran--and soon--but to stop her, you'll need some- thing...”
The Maku Tree after restoring her in the past:
“Maybe Veran is using Queen Ambi to raise the tower to the heavens. If one of impure heart gains the powers of shadow... this world will be covered in darkness. That's what this is about... To know the past is to know the present. Veran can do as she pleases if she finds dark power in the past. All will go dark! Link! You must stop Veran and save Nayru!”
Nayru, after you save her:
"But Link, Veran's still in the past, right? If she is, then can't she still create an age of darkness that would continue to the present?"
Veran when the Black Tower is almost completed:
“Heh heh heh heh! We are closer to the Age of Shadow! But it's still premature. The true shadow will fall when the Black Tower reaches the heavens and I climb to its highest turret! Then it will come... Heh heh heh... Hah hah hah hah!”
Veran, gaining the powers of darkness:
"Ah hah hah hah! The Black Tower is finally complete! Powers of darkness, come to me!
Ahh! The powers of darkness flow through me! The powers swell! Hah! Even without the powers of young Nayru, I can stop time! Now true darkness comes! The sorrow of people shall be delivered to me, lighting my Flame of Sorrow! Ah hah hah hah!"
