The Hakulea Expedition

Hakulea Expedition didn't use any navigation techniques other than what the ancient ones had figured out. So first of all, you had to know this ring of stars around your island. And there's also other things you had to understand like the swells in the sea. If we're going to go in the direction of that star, we don't point our boat north, northeast. We have to point it in a direction that takes into account the wind, but also the movement of the seas.
