Long after settlers found Hyrule, there arose the Gerudo, and then years later, the tyrantical ruler Ganondwarf appeared,
and he used his power to create a blade of bloodshed and evil; the Nightfall blade, and he also used his power to augment a shadow;
the shadow of Link,
and with this shadow, Ganondwarf ordered the shadow to draw the Master Sword for himself, and so the shadow did,

and with his greed and ignorance, Ganondwarf was killed by the dark figure, by using the Master Sword against him, and took the Triforce of power for himself.
The dark figure then proceeded to erect a massive tower, and he also sealed away the Nightfall Blade, with the power of 7 descendants of the 7 wise men,
knowing that the Nightfall blade's power was too risky to be in the wrong hands.

The dark figure then proceeded to slowly take control of Hyrule, and corrupt it.
