"Monster: A word used to discriminate the unknown"
The reason I ask or even purpose this therory is because in every game before "Twilight Princess" Link always had a reason to have the Triforce of Courage, in "Ocarina of Time" it is because Ganondorf indirectly gave said piece of the relic to Link by just touching it. The Hero of Twilight never was forced to collect it, nor was he alive when Ganondorf obtained it. Link, though he was forced to transform into the divine blue-eyed beast to quote-un-quote "survive the harsh conditions the twilight realm", we clearly see him walking in the Palace of Twilight in the true Twilight Realm, not artificial like the twilight covering Hyrule. We also know that twilight did cover Hyrule the people of light had one of to things happen to them, this evidence comes Zelda 'first visit' and Barnes 'listening to the spirits of Kakriko Villiage in a twilight covered hyrule', they either turn into spirits or shadow beasts. When Link finds out he us the chosen hero, it is only after he has already transformed. The game also never mention Link's parents at any point throughout the game, so who's to say the goddesses chose him because he was able to survive the harsh twilight realms conditions, unaware he was only able to do so because of his bloodline.
