"A nation of humans has sunk into the sea.

We can still gather evidence that a human nation once existed there.
However, over time, such historical data will decay and be lost forever.

What we want you to do is to pick up that data before it's lost, convert it into a format we can understand, and share it with us to help us understand humanity.

However, please be careful.

Your body is fragile and will crumble if you touch anything other than data.

This is a dangerous journey.

But we hope that at the end of your journey, you will bring back information important to our future."


You play as a whale exploring a fictional human nation sunken to the bottom of the sea.

It's not a real nation, and it's not a real event.

But perhaps it is a nation of possibilities that may exist somewhere.

I hope you can feel something through this adventure.
