Call me Tingle, I completed a super-map of Hyrule and all of the other provinces Link has visited in the Legend of Zelda Series. In it, I included the Hyrule from Twilight Princess, Termina from Majora's Mask, Labrynna from Oracle of Ages, and Holodrum from Oracle of Seasons. I originally planned to include Koholint Island, but I have three reasons why I didn't:
-It would've made the image much larger than it already is.
-I wouldn't be sure where to place it.
-Link's Awakening was a dream, and therefore the island was most likely a figment of Link's imagination.

Well, anyway, this took me some good time, sketching out the lines to make it fit and at the same time not to look too boxy, especially so for Holodrum and Labrynna.

Anyway, the key.
-Light Green, Border or raised structure. thin lines indicate a ledge or bridge
-Dark Green, Walkable area
-Blue, Water
-Dark brown, uncharted land.

So, hmmm, Nintendo, Regi said you have plans to make an MMO for the Wii, I've got the map, now go for a Zelda MMO.

Some locations were made up by me.

EDIT 12/17/07: I'm rather impressed by how critically acclaimed this piece is. I may end up making a physical map with terrain features, so stay tuned.
