Sturgeon

Sturgeon is a recurring character in the Zelda series, first appearing in The Wind Waker.

The Wind Waker
In The Wind Waker, Sturgeon is a wise, elderly man who lives on Outset Island with his granddaughter, Sue-Belle, on the upper floor of a home where his younger brother, Orca, also resides. Whereas his brother will spend the entire day studying the art of fighting, Sturgeon will lock himself in his room and study all day, expanding his knowledge. Although very wise, Sturgeon has a very hot temper, and is hardly accommodating. He is easily angered by Orca's training, and often refers to his brother as a "hooligan". Even though he despises swordfighting, he was actually once an accomplished swordsman himself.

At the beginning of the game, Sturgeon will teach Link the game's basic controls, such as L-Targeting. In Sturgeon's room, Link see will papers tacked to the walls, titled Sturgeon's One-Point Lessons. These articles contain useful information on basic game mechanics, such as Recovery Hearts, Saving, the use of Area Maps, and so on.

In his youth, Sturgeon set out with his brother on an arduous quest to collect ten Knight's Crests, which would allow them to learn a powerful new sword technique. However, even after many long years and adventures beyond count, they were unable to even approach finding ten crests, and they both grew old. If Link brings presents 10 Knight Crests to Orca, he will teach Link the technique that they were never able to master: The Hurricane Spin.

The Minish Cap
Sturgeon also makes an appearance in The Minish Cap where he spends most of his days in the library in Hyrule Town. Sturgeon is convinced that some of the books from the library move on their own. It is, in fact, the Minish who live in the library who are behind this.
