Zauz

In The Legend of Zelda: Phantom Hourglass, Zauz is the blacksmith who helps Link by forging the Phantom Blade used to defeat Bellum. He also tells Link how to dive deeper into the Temple of the Ocean King, with a secret drawing to find the chart that will help Link. It is around this time that Link makes his first encounter with the Swift Phantom.

When first speaking to Link, he mentions that he is not of the human race. he later explains that his people once served the Ocean King long ago. Zauz has a large purple tattoo running over his shoulder similar to that of Baito, and off colored nose and orange eyes. A Sheikah possibly?
