Essential Tips for Ultima Thule

The Void: Do not try to walk off the edge of an island to reach another one. You will die. Wait for the bridges of light to appear as part of the story.
Chi Fate: The large platform in the northeast (The Lost Hydraulic) is for a boss FATE and does not contain aether currents.

Embarking on this quest is an invitation to journey to the edge of existence. From the sorrow of the dragons to the apathy of the Ea and the despair of the Omicrons, finding these currents is the final step in your journey to the stars.
