Firstly I finished my post, now an explanation for the cryptic hints given by Faron.
Alright now a lesson in Zelda history that I totally made up:
In the beginning the worlds were not separated. Each meshed with the next as lands some bordering others far above and some deep below. This however was not limited to peaceful lands such as the Fairy Realm or Lorule. This included awful realms of the most despicable nature, when the golden goddesses departed the world leaving the Triforce behind evil creatures crept forth from these vile lands seeking the power for themselves.
Hylia the goddess left on charge of the world was despaired for though she could destroy many thousands even more took their places. In her greatest moment of need Hylia called upon the most skilled of the Fairies to forge her divine weapons by which these beasts could be held at bay.
The two most skilled fairy sword smiths, brother and sister labored for seven days and seven nights to create the two most perfect swords ever forged. Just as the fairies completed these works of art they lay down to rest and passed into the next world their aim in life complete.
These two brilliant swords forged in Goddess flame shone brighter than the stars and were capable of wielding the power of the night and day (one each). Some say that a small part of the spirit of those that forged them was imbued into the blades. As such they were called Spirit swords.
The one that commanded the power of the day was called Luna and the one that embodied the night Sol. They were identical in every way except that Sol was forged of a black alloy the same shade as a summers night while Luna's blade was a brilliant as a shining sun.
Hylia used the two blades to call down the power of night and day and with it she forged the walls between the worlds. She cut off the demon lands sealing all but the most cunning in their homeland, she separated kingdom so as they would never see war and she separated a special space to hold the power of the gods so that no one could get their hands on it.
Unfortunately Hylia's solution while effective had come too late, a Demon Lord called Demise had clung to this reality in a desperate bid to obtain the power of the Triforce.
He and an army of demons he brought with him made war on Hylia. At first they were unsuccessful; with Hylia wielding both Luna and Sol not even Demise could touch her.
Late one night the demon king came up with a plan to steal one of the spirit swords. He took one of his minions, a wraith and cloaked it in black armor. He called the new creature a Darknut. The armor it wore would allow it to survive the power of the blades, for a little while anyways.
When Hylia was sleeping the Darknut snuck into the Temple of Hylia and took the night sword: Sol.
As he returned to Demise the Darknut burned to ash from the sword's power. It had done its job though; the spirit sword belonged to Demise. Over the next seven days and seven nights while Hylia scoured for her lost blade in vain Demise corrupted it. He tempered it in fairy blood and the fires of burning cities warping the mind of the spirit sword till it no longer remembered its former master's name. As the spirit became warped so did the blade till it was nearly unrecognizable. Demise gave the spirit sword a new name: Ghirahim. Confident in his new weapon Demise again went to war with Hylia.
Both Luna and Hylia grieved Sol's fate. The goddess wiped Luna's memories of her brother to ease her suffering and gave her a new name so she'd never realize she was one of a pair. This name was Fi.
The goddess then set off on a desperate plan depicted in the Skyward Sword. After this when the first Hero defeated Demise and the spirit sword was rescued the fairies took the dark blade hoping to repair the once great work. Though they tried Fairy’s Tears and Goddess Fire it appeared nothing could return the blade to how it once was.
With sorrow in his heart the King of the Fairies ordered the blade be shattered and its pieces scattered through the realms.
That sword is Hylia's lost power that Faron mentioned; both the Master's Sword and Ghirahim were used to make the barrier between the worlds so both are needed to restore them. We have to gather the shards of the blade and have the fairies repair it. The handle is in the possession of the royal family.
Anyone have any objections to this part?
Second the tremor that shook Hyrule was our bad guy realigning the walls of the world to lock out the guardian's that usually aid Link: Light Spirits, Deku Tree all those guys.
And dude playing Ravio that tremor was a temporary break in the walls which means if Ravio was at the wrong place at the right time he could cross over onto Hyrule.
Oh and just so you’re aware, Ravio's bracelet got fried when Hilda used it to send Link and Zelda back to Hyrule.
