The Legend of Zelda: The Wind Waker is staged as a game set in Future Time from Ocarina of Time. approximately 100 years.

There is a Triforce in The Wind Waker, seriously...oh come on...I mean it.

Aril is Link's Sister. She is Kidnapped at the beginning and you don't see her until later in the game. Link must save her.

Ganondorf is back again and he is looking for Zelda, he has ordered a bird called the Zeetlock to capture all the blonde girls in hopes that he can find Zelda.

There is a character Tetra, who is a pirate, but this pirate is not exactly who she seems... Sound familiar, well you'll have to play the game to know more.

The reason why Hyrule is covered in water is because it's been flooded, apparently by a certain person of hylian royalty.

There are a lot of new characters to be found in this game that you'll just have to wait and see to learn about.
