Valley of Seers

The Valley of Seers is a stage in. It contains "The Sorceress of the Valley", "Shining Beacon", and "March of the Demon King", the fourth, thirteenth, and fifteenth Scenarios in Legend Mode, respectively. In the Master Quest DLC pack, it also contains "Darkness Falls", the fifth and final Scenario in Cia's Tale.

The Sorceress of the Valley
After learning that it was Cia who opened the Gate of Souls and used it to summon monsters and invade Hyrule, Lana joins Link, Impa, and Sheik and accompanies them with the rest of the Hyrulean Forces to the Valley of Seers, where they seek to close the gate and thus stop the tide of monsters pouring out from it.

With Cia waiting atop the Ruins Summit and summoning more Dark Forces to attack the Hyrulean soldiers, Sheik suggests that they capture the West and East Keeps to provide a foothold against the Enemy Base. However, Volga soon appears and engages in combat against Impa and her soldiers, delivering powerful attacks against the Hyrulean Forces. After Lana aids Impa in defeating Volga, he flees from the battlefield and allows the Hyrulean Forces to capture the two vital keeps. This leaves a path to the entrance to the ruins, but the allies find that it is being blocked by vines and the only way to get into the ruins is by lowering the bridge in the east side. It is then that an Engineer offers to assist them and begins to head out to it from the Allied Base while the Hyrulean Forces protect him from the advancing Dark Forces trying to stop him.

Once the Engineer safely reaches the East Ruins and lowers the bridge, Cia sends Summoners to the battlefield to thwart the Hyrulean Force's advance. Furthermore, the allies discover that there are vines impeding the path to the summit of the ruins, thus Lana searches the Western Room for an item capable of cutting them down. Conquering the temple reveals a Treasure Chest containing the Boomerang, which Lana, Link, Impa, and Sheik use to enter the Ruins Summit and confront Cia once and for all.

At the summit, the dark sorceress continues to summon monsters from within the Gate of Souls but stops when she realizes that her Triforce of Power is resonating due to Link and Sheik arriving at the scene. Sensing the presence of two pieces of Triforce, she summons Manhandla from within the Gate of Souls. Although the giant monster begins to attack the Allied Base, it is quickly defeated by the Hyrulean Forces. Back at the altar of the ruins, as the Hyrulean allies are readying to close the Gate of Souls, Cia summons a dark circle and engulfs the allies from below, stealing Link and Sheik's Triforce pieces. With the Triforce complete, Cia opens three Gate of Souls from across three different timelines and frees the fragments of an evil spirit within her, empowering the dark sorceress even more and leaving only one fragment left to free: the one guarded by the Master Sword.

Due to Cia opening the Gate of Souls through the ages, three portals from different appeared in the present day Hyrule. The young heroes, left with no other option but to split up and handle all three gates simultaneously, each depart to a different era, all charged with the task of closing their gate and returning safely from their quest.

Shining Beacon
After defeating Cia's Forces at the Temple of Souls, Link and the Hyrulean Forces hurry back to the Valley of Seers to confront Cia for the final time. Cia however prepared herself immensely by fortifying her troops with her own life force, improving their Morale. The Hyrulean Forces enter the valley, but the Allies face a disadvantage as they find themselves split between the east and the west side. Lana discovers that specialized Keeps, Sanctums, were taken over and has their sacred power locked away. The Hyrulean Forces' commander, Princess Zelda (Ruto if playing as Zelda), advises that these Keeps be conquered to take back their power.

Zelda and Fi leave to find the Sanctums, while Lana intercepts the Western Keep. As Link fights to reclaim the Sanctums, Cia opens the West Ruins Room as enemies pour out to hunt down Zelda. She eventually sends more troops after Fi as well, all the while enhancing her troops with more of her energy. Eventually Link manages to conquer the two Sanctums, but Zelda senses that an evil power still persists. Lana tells her not to lose hope yet, as a third Sanctum also exists within the valley. She heads south to find the last one. After locating it, the Hyrulean Forces quickly conquer the final Sanctum, diminishing the Dark Forces' strength. Their success infuriates Cia, and she uses more of her life force to summon enemy reinforcements. Lana begs with her to stop as her spirit cannot take any more stress.

As the situation worsens, the Great Fairy beckons Zelda to come to her Fairy Fountain as the gateway opens. She quickly advances to the fountain with Impa in tow, and makes the fountain their Base. Darunia and Midna also hurry to the fountain as well. Zelda then devises a plan to draw as many enemy troops as possible in front of the fountain to stage their next plan of attack by using the fountain's Magic Circle. Cia, meanwhile, brings Volga onto the battlefield as she fortifies him with her power. With his new strength, he quickly leaves to intervene Zelda's plan, and enters the north area of the fountain. As Cia's troops gather around the fountain, Zelda commands the Magic Circle be used now. The circle summons the Great Fairy, who sends a massive bolt of light from the sky to strike down the enemies below, causing large-scale causalities. Alternatively, if the Hyrulean Forces summon the Great Fairy too early, Cia's army suffers little loss and grow in Morale.

The Great Fairy's attack greatly diminishes Volga's power and health. In his rage, he advances to strike back and regains Dark Power which recovers his health. Volga confronts Zelda and fights with her, however she reasons with him and questions how he could take joy in using Dark Power. She attempts to convince him that he should fight as a proud warrior, and not as a tool for the Dark Forces. Her words manage to convince him, and Volga regains his senses as pushes the dark from him. He then locates Link to fight him in a fair fight, but is soon defeated. Volga collapses, implied to have perished, and the front gate to Cia's base is opened.

Link then confronts Cia at the valley peak. During their fight, Cia uses the power of darkness to split herself into four copies. Despite this advantage, Link defeats her and the copies and the battle comes to an end. As Cia lays on the ground dying, Lana arrives and runs to her side. Cia passes as she fades away, and bequeaths the Triforce of Power into Lana's possession. With the war now seemingly over, Lana sends Darunia, Ruto, Agitha, and Midna back to their respective eras, and closes them with the help of Link's and Zelda's Triforce pieces. Hyrule's peace does not last long, however, as Ganondorf's final spirit fragment is released as the result of the Master Sword's removal from its pedestal.

After completing the Scenario, Ganondorf is unlocked as a playable character and his weapon, the Great Swords, becomes available for use.

March of the Demon King
The third visit follows the events from "Ganondorf's Return" in the Gerudo Desert. With his army finally built, Ganondorf marches along with his servants Zant and Ghirahim to secure the scattered Triforce pieces. He first arrives to the Valley of Seers seeking the Triforce of Power, which resides with Lana who had fled to the valley in an attempt to escape him. Ganondorf's Forces follow her there and are confronted by the opposing Hyrulean Forces' Gorons, with more reinforcements rushing to Lana's aid.

While attempting to reach Lana, Zant senses a sacred power in the valley's three Sanctums, and believes conquering them would give them an advantage. Zant and Ghirahim leave for the Sanctums, but Lana uses this as an opportunity to trap them inside. Ganondorf arrives to their rescue, by conquering the two Keeps and thus opening their gates. The take over of the Sanctums reduce the valley's sacred power, resulting in Lana's forces losing Morale. Just as Lana's situation turns critical, Impa and more reinforcements enter the battle and try to intervene. She splits herself into four other copies and scatters herself across the field. Fighting the other copies, however, proves to be fruitless for Ganondorf's army as they respawn. Zant then suggests they should continue to pursue Lana, which would make the real Impa reveal herself and rush to Lana's location to defend her. While Ganondorf pursues her, the real Impa reveals herself and is fought. After she is defeated, she hints towards a plan that suggests Lana will be able to escape. Immediately afterwards, she leaves the battle.

Ganondorf continues onward to the top of the valley, eventually confronting Lana. Upon defeating her, she suddenly warps away and relocates to the Fairy Fountain Keep. Impa from afar then instructs her to use one of the Magic Circles she had set up during the confrontation with Ganondorf to escape the battle. To further increase her chances of escape, Lana splits herself into two copies as both attempt to reach different Magic Circles on opposite ends of the battlefield. Ganondorf and his Forces charge after her, and defeat them both. He obtains the Triforce of Power, and sets out to Hyrule Castle to claim the remaining pieces of the Triforce.

Darkness Falls
Set prior to the events of "Shining Beacon", Cia's hopes were beginning to wane thin at the defeat of Volga, Wizzro, Zant, and Ghirahim at the hands of Link and his allies. Meanwhile, Ganondorf, who had managed to manifest his form despite not all of his spirit fragments returned, was making his way to the Valley of Seers to steal Cia's Triforce of Power. With very little options left, Cia became desperate and tapped into her own life force to increase her magic power. She knew this would risk her life, but her desire for victory outweighed the costs. With Ganondorf now heading into her territory, she prepared herself and her troops for his arrival.

Ganondorf immediately summons his greatest troops into the battlefield, and sends two large Gohmas to capture Cia's Keeps - one in the east and one in the west. Cia has her general Volga defend the east Keep, while she leaves for the west Keep. En route, she faces and defeats one of the Gohmas. However, Ganondorf has a back up plan and summons Manhandla onto the western field as well. The plant monster begins a seed barrage attack on the Allied Base, and Cia orders Wizzro to intercept. Wizzro begrudgingly accepts, despite his wounds not yet fully healed from the last fight. As he advances to Manhandla, he takes notice of and interest in Ganondorf's superior command over his troops. As Cia focuses on the last of the Gohmas, Ganondorf's Forces begin to advance in larger numbers. The Gohmas' defeat defends the Keeps, yet Cia does not miss a beat and immediately orders Wizzro to cut her a path through the enemy ranks. Wizzro however refuses to follow and announces his allegiance to Ganondorf. Only a little impressed, Ganondorf tells Wizzro to prove his loyalty by defeating his former allies. Wizzro happily accepts and both him and traitorous Icy Big Poes begin attacking Cia's Dark Forces. He also uses magic to increase his strength.

Cia is furious at Wizzro, and swears that she will annihilate him for his treachery. In response, Wizzro summons more reinforcements and threatens her with his full strength. Although Wizzro's treachery is gravely troubling, Volga reminds Cia that they must first deal with those threatening their base. Cia leaves to defeat the Manhandla from before, as well as the Icy Big Poes heading for the base. To increase their chances, Cia uses her dark magic and summons multiple Dark Links to aid her in her fight. She becomes delusional and views them all as the hero Link, her love. Volga however becomes concerned at this display, and suspects her constant use of dark magic is worsening her state of mind. He deems that she is no longer worthy of his services, and leaves to confront Ganondorf himself in a battle between them alone. But Ganondorf has no interest in fighting him, and instead constructs a Barrier of Darkness inside his base and traps Volga inside. With no way past the barrier, Volga is forced to temporarily retreat. Cia meanwhile, after removing the threats to the Allied Base, moves to combat Wizzro. She defeats him and seals him back inside the ring he came from.

With Cia now fighting on her own, Ganondorf uses this opportunity and summons hordes of monsters in the south. His troops advance to storm the ruins, resulting in a a few of his Keeps opening. Volga then rejoins the fight in the north, and is at awe by Ganondorf's sheer power. Cia orders him to return to the base and guard it at once, however he refuses her order and announces he acts on his own now. He advances to take down Ganondorf's Forces once more. With Ganondorf's Force overwhelming them, a fraction of Cia's Dark Forces also flee. Frustrated and losing hope, Cia delusively tells herself that the hero Link (referring to the Dark Links) is still by her side.

In that moment, Lana suddenly appears at the Fairy Fountain Keep. She pleads with Cia to stop using the dark magic as it is destroying her mind. Cia is surprised by Lana's appearance, but remembers that she still needs to defeat Ganondorf. Lana tells her that she will help her, and together they can defeat him. Ganondorf is confused by their appearance as he thought he had separated them permanently, but it matters little to him and he resumes his attack. He opens his Base and amplifies his magic power using the barrier, growing stronger by the minute. Lana presses that they must defeat him now before he grows too strong, but Cia says that the barrier is so strong they cannot get close. Lana responds that she can dispel the barrier, but only with Cia's help. Together the sorceresses advance to the Enemy Base. Ganondorf's strength continues to grow in the mean time, however he feels it is still not enough. Should more time pass, he grows even stronger and mocks them for their hesitance. Eventually Lana reaches the Enemy Base and use her powers of light magic to dispel the barrier.

With the barrier now dispelled, Ganondorf's strength weakens. He is not worried in the slightest however and swears he will still destroy them. Cia then enters and attacks the base. Using their combined strength, Cia and Lana defeat him together. Having lost the battle, Ganondorf is forced to retreat. Lana is relieved to have defeated him together, but Cia impatiently instigates that Lana must leave now. Lana again tries to plead with her to stop using dark magic, but is unsuccessful as Cia demands she leave at once.
