The Legend of Zelda: The Wind Waker/Species/Kokiri

Backstory
The Kokiri were a people who resided in forests prior to the events of The Legend of Zelda: The Wind Waker. Their appearance in The Legend of Zelda: The Wind Waker as small humanoids who are associated with the forest and clad in green clothing is not too different from their depiction in The Legend of Zelda: Ocarina of Time.

Current State
By the time the events of The Legend of Zelda: The Wind Waker not a single Kokiri is seen alive in the game. Only the ghost of a Kokiri sage is ever seen by Link.

However the Kokiri do play an important role in the game, through their descendants in Korok, who have established one of the largest settlements seen in the game.
