Link (Your Character)
hyRULES
It is most probable that Link was born in Hyrule and so was Zelda but for link it seems to be different as he thought he was a kokiri and was not raised there therefore the proper term is that they were born in Hyrule and link raised in either castle town or kokiri village but Zelda as a princess was most definitely raised in hyrule castle.
Link lives on the Island of Hyrule ( he , as well as Princess Zelda, are Hyruleans).
because he is the link from the game to the player,-nintendo, Hyrule Historia
If I am not mistaken, mind you it has been years since I played it, but Link left Hyrule by boat and was shipwrecked on an island some where in the sea. It does not take place in Hyrule Kingdome.
you have a town called hyrule and have characters named like that. that's all
He is an orphan, but his bloodline is from the Knights of Hyrule.
Link save Hyrule.
This is because the game is not set in Hyrule.
link was born in hyrule and so was Zelda. but it changes depending on the game
