It all begins with a simple question. Who knows the location of the Triforce in OoT? This is simple; the Royal Family have handed this knowledge down from generation to generation.
I'm going to tell you the secret of the Sacred Realm that has been passed down by the Royal Family of Hyrule. Please keep this a secret from everyone... [...] That's right... The Temple of Time is the entrance through which you can enter the Sacred Realm from our world. But the entrance is sealed with a stone wall called the Door of Time. And, in order to open the door, it is said that you need to collect three Spiritual Stones. And another thing you need...is the treasure that the Royal Family keeps along with this legend... The Ocarina of Time!
So do the Royal Family maintain this knowledge even towards ALTTP? Nope.
...the Triforce grants the wish of the one who touched it. As long as that person is alive... That, surely, is why it was placed in the sacred land, and its location passed down only among those chosen. However, it looks as though that was interrupted somewhere... Then, the one who again discovered the sacred land was the thief called Ganondorf.
So in order for OoT to lead into ALTTP, we need an event that can establish the loss of the knowledge of the Sacred Realm. Without speculation, we have such an event; TWW's Great Flood. The Great Flood was the event that "interrupted" the knowledge of the location of the Sacred Realm that had been handed down by Hyrule's Royal Family. Of course, there is evidence that the Great Flood was responsible for much more than this.
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.
The general implication from this text is that Hylian civilisation had died out long before the events of the SW, leaving only relics and myths as to explain Hyrule's history. The term "golden power" for example was never used by the people in OoT. In fact, the true name of the Triforce was only revealed in ALTTP when the Sages' Seal was broken and the transformation of the Sacred Realm by Ganon had been revealed to all. Furthermore, the people in OoT did not need to search all of Hyrule for the entrance to the Sacred Realm because legends of the entrance had indeed passed to them.
Do you know about the Temple of Time that we have in the northeast part of town? Legends say that the Temple of Time is the entrance to the Sacred Realm... Did you know that?
Legends say that the Temple of Time is the entrance to the Sacred Realm...
Then there is Hyrule's geography. TWW's Great Deku Tree explains to us how the land of Hyrule can be raised up from below the waves by connecting all the islands as one where human civilisation can rebuild itself.
Every year after the Koroks perform this ceremony, they fly off to the distant islands on the sea and plant my seeds in the hopes that new forests will grow. Forests hold great power--they can change one tiny island into a much larger island. Soon, a day will come when all the islands are one, connected by earth and grove. And the people who live on that great island will be able to join hands and, together, create a better world. Such is my dream. ...But the one you are chasing is trying to prevent that dream from ever coming to pass.
Link... Already, your fate is tied to the fate of this world. You must proceed with great care.
Ganondorf appears to confirm this when he tells us that the Gods intentionally left people to awaken Hyrule (not find a new land).
What did the King of Hyrule say? ...That the gods sealed Hyrule away? And they left behind people who would one day awaken Hyrule?!
Now in the backdrop of the Palace of Winds in TMC, we can see two islands below.

This begins a definite continuity that shows Hyrule physically expanding from below the Great Sea. As time goes by, Hyrule expands and connects with other islands to form larger islands.
-TMC shows Hyrule as a small area of land, with other islands around it.
-FSA shows Hyrule as a larger island.
-ALTTP shows Hyrule as FSA's map but with mountains instead of sea borders.
-AoL shows Hyrule as part of a much larger land-mass, Calatia.
Finally, there is the FS saga itself. Have you ever wondered why the Triforce or the Sacred Realm have never enterred the storylines of the games; why Vaati and Ganon never sought to take the ultimate power when they had the opportunity to? This distinctive detail connects with the fact that after the Great Flood, no one knew where it was or or exactly what it was. The SW scripts labels the finding of the Triforce as an accident; the Sacred Realm was stumbled upon by Ganondorf and his group of thieves. After this event, such understandings became known to the Sages and the Royal Family. This is not to suggest that FSA leads into ALTTP, because I don't think it does. However, the events are explainable when positioned between TWW and ALTTP.
