Dazzle Lyphos

Dazzle Lyphos is a character from Freshly-Picked Tingle's Rosy Rupeeland. He is not alive during the events of the game, but he is a legendary figure who was once the protector of Port Town. When saving the town from danger, he lost his life, and became a historical figure. The residents of Port Town constructed a grand monument for the hero where the entrance to his underground vault was located.

Theory
It is likely although never explicitly stated, that Dazzle Lyphos is somehow related to Link. This concept comes from several in-game quotes, where citizens of Port Town explain that he was the descendant of a legendary hero who saved the world.
