The Imprisoning War narrative, from the original Japanese SNES manual:
In the times long past, before man first emerged, the gods descended upon the world when it was nothing but chaos. Using their various abilities, they brought order and life to the world. The God[dess] of Power used [her] flame to dye the mountains red and made the earth. The God[dess] of Wisdom made science and magic, and awarded the land with natural order. And the God[dess] of Courage used the kindness of [her] strong heart, and created those which crawl on the earth, those which travel in the air, and all of the living creatures of the world.
After forming all that is, when it was time for them to depart this realm, the gods consummated the land with a symbol forged of their own power, in the form of a sacred, golden, triangle: the Triforce. Their course finally running to completion, the gods left the Triforce to govern this land. The Triforce, respectively: "one who would Conquer Power," "one who would Govern Wisdom," and "one who would Temper Courage" held three different emblems. It would shine in the Sacred Realm, somewhere in the world, until one who was worthy of inheriting those powers appeared.
Hyrule, where many Hylian relics have been left, is an area very much tied to myth. One such example is an old saying about the Triforce: "The golden power lies somewhere descended from the heavens. He who claims it as his own shall have their desires granted by the gods."
The people, seeking the Golden Power, began searching for the Sacred Realm. Many reports began to surface; lying beneath the relics of the desert, inside the graves of the race of people in the high mountains, but no one ever found it. Longing soon became greed, and it was not uncommon for blood to be spilt for certain information. The more carefree people had to live days of disquiet.
That is, until one day, completely by change, the entrance to the Sacred Realm was opened by a certain group of thieves. It was a world different from our own. The Triforce was there, casting a golden light in the midst of twilight. The group began to push one another aside and tried to press forward. After the bloody confrontation among comrades had ended, the victor was the leader of the group.
When the leader touched the Triforce, his hands stained in fresh blood, the emblems' spirits began to whisper. "If thou hast a desire, then I shall desire it as well." Crossing time and space, the leader began to laugh so loudly that it is said to have echoed all the way to the distant Hyrule. The man's name was Ganondorf, and his common name was Ganon of the race of evil thieves. Indeed, the King of Evil Ganon, the one who has threatened Hyrule so, was born at this time.
We do not know what Ganon wished for after gaining the Triforce's power. Yet, Ganon's evil made it to even Hyrule as it spread. People of greed were herded and consumed by this power, and disappeared. Black clouds grew in number in the sky, and many sinister happenings began to occur. The King of Hyrule called upon the Seven Sages of Hyrule, as well as the Knights to seal the source of this evil.
The Triforce itself cannot judge between good and evil. That is because only the gods can do that. However, it could not be assumed that only a good person would get their hands on the Triforce. For that reason, the people of Hyrule were told by the gods to make something that would repulse any evil that may kidnap the Triforce: the blade of evil's bane. It was called the Master Sword, and it is said that only a true hero could use it. The Sages first had to search for the existence of the Master Sword and a hero to use it.
However, the situation was urgent, and Ganon's malice was enclosing on the royal palace. Using the most of their powers, the Sages and Knights threw open a heroic battle with the evil one. The Knights valiantly used their bodies as shields during the fierce attack,although they unfortunately perished when their strength had exhausted. Nonetheless, the Sages completed the seal.
The people celebrated their victory; Hyrule had been saved from Ganon's misuse of the Triforce's power.
Comparisons to OoT:
The ALttP Imprisoning War narrative starts with the creation as an explanation of the origins of the Triforce and of the Sacred Realm. It establishes that the Triforce was left behind in the Sacred Realm, and that legends of it were passed down in Hyrule. OoT has the exact same background: the creation, the Sacred Realm, and the legends of the Triforce.
Before time began, before spirits and life existed, three golden goddesses descended upon the chaos that was Hyrule: Din, the goddess of power; Nayru, the goddess of wisdom; Farore, the goddess of courage. Din, with her strong flaming arms, she cultivated the land and created the red earth. Nayru poured her wisdom onto the earth and gave the spirit of law to the world. Farore, with her rich soul, produced all life forms who would uphold the law.
The three great goddesses, their labors completed, departed for the heavens. And golden sacred triangles remained at the point where the goddesses left the world. Since then, the sacred triangles have become the basis of our world's providence. And, the resting place of the triangles has become the Sacred Realm.
After talking about the Triforce, the ALttP myth describes that chaotic struggles erupted in Hyrule over the Sacred Realm and the Triforce. OoT establishes that there was a fierce war in the world before the game's events, and later TP provides a background for this struggle- depicting it as a rivalry over the Triforce and describing a dark tribe that came about in the midst of the struggle (previously described in FSA).
Some time ago, before the King of Hyrule unified this country, there was a fierce war in our world. One day, to escape from the fires of the war, a Hylian mother and her baby boy entered this forbidden forest. The mother was gravely injured... Her only choice was to entrust the child to the Deku Tree, the guardian spirit of the forest. The Deku Tree could sense that this was a child of destiny, whose fate would affect the entire world, so he took him into the forest. After the mother passed away, the baby was raised as a Kokiri.
The goddesses descended to the world of chaos where there was nothing at all, and created life and order, and after granting power equally to all people, they returned to the heavens. The place where the goddesses first landed is called the holy land. For a long time, the world was at peace, with people's hearts being deeply faithful.
But at length, a rivalry ensued over Hyrule, the holy land. In the midst of the people, persons who excelled at magic appeared. With powerful sorcery, they tried to rule the holy land, but the goddesses sent us light spirits to seal away the gigantic magic of those people. That very sorcery is the black power: the Fused Shadow.
ALttP then goes on to describe Ganondorf's entry into the Sacred Realm and seizure of the Triforce, just as happens in OoT. He discovered it by "chance," which matches up his his discovery of it in OoT, in which he gambled on Link's success. The massacre of his followers is missing, but could easily have happened off-screen. It's not missing pieces that invalidate OoT as the IW; contradictions would have to exist, and there's no real contradiction in OoT- Ganondorf finds and enters the Sacred Realm and touches the Triforce and becomes the evil king Ganon. We even see the same words the Triforce whispered to Ganon in TP (a known OoT sequel): If thou hast a desire, then I shall desire it as well.
We know that evil spread to Hyrule in OoT, because we see its effects. We know that someone ordered the Sacred Realm to be sealed because the awakening call issued forth from the Sacred Realm to summon the sages (blocked of course by Ganon's power). We know that a hero bearing the Master Sword was sought for, because Link and the Master Sword were missing and waited for for seven years. We know that Ganondorf attacked the royal palace as described, because the castle is in ruins. We know the seven sages completed their seal, because we see it cast in the end of the game.
On top of this, two separate developers stated specifically that OoT was developed as the IW.
What's there to keep OoT from being the IW?
