This island seems connected to the puzzle in some way. Activate its Flow Gate and see if Caleri has any ideas.
Caleri: It is... wonderful. Although there's some strange cloud coverage around here...
Caleri: This island must be connected to the experiment somehow.
Caleri: Hmmm... maybe we need to get food for the soon-to-be-hatchlings?
Caleri: Where are we going to find any up here?
Caleri thinks the island is related to the puzzle. Try exploring to find a source of food for the Silverwings. What could be hiding in the clouds?
You've found a Cloudminnow! Try catching more from the thick clouds around the island.
Caleri: Incredible! These are Ancient Cloudminnows!
Caleri: Today's Mudminnows were rumored to have descended from them.
Caleri: I thought they were just legend, and yet... here we are.
Caleri: A formerly extinct species, in the flesh.
Caleri: We need to get writing! Nobody will believe this...
