History
Hyrule was created by the Golden Goddesses: Din, Nayru, and Farore. After the goddesses were finished with Hyrule, they created another parallel world known as the Sacred Realm. Before departing the realm, the Golden Goddesses left behind the three golden triangles filled with their power, these three triangles when put together would become a larger triangle known as the Triforce. After this, Hyrule was at peace for a number of years.

Some time after the events of SS undefined, the legend of a supreme power spread across Hyrule, causing a great war over the location of the Sacred Realm. During this war, the tribe skilled in dark magic known only as the Interlopers attempted to establish dominion over the Sacred Realm and establish their power using the Fused Shadow. Ordered by the Golden Goddesses, the Light Spirits intervened. They sealed away the great magic those individuals had mastered, and splintered it, so it became the fragments of the Fused Shadow hidden in the temples of Hyrule. The goddesses chased the interlopers across Hyrule and banished them to the Twilight Realm using the Mirror of Twilight.

The descendants of the Interlopers became the Twili, doomed to live as mere shadows in the Twilight. During this conflict, Rauru sealed the entrance to the Sacred Realm.
