You land at a very special time when light is blocked by an eclipse as seen by the planet's rotation. This eclipse is very short and we use it to make sure you see the highlights and fire in this tutorial.
However, in our tutorial time passes based on events and not time passing.
On Island 3, the campfire will last a few min. Once you make it, the eclipse starts to end and the 2 moons begin to show themselves in the sky along with the bright sun.
