A Peaceful Place

At some point in the distant future, lost in the depths of some ocean, lies home to a civilization of aquatic beings.

Although socially divided, it feels a collective calm.
Some lucky ones, they lack nothing. What do they worry about?
Others unfortunate, who have nothing left over, but the path ahead inspires them.
And those in between, that just where they are, are okay.

This unknown city is always welcomes new inhabitants.
Are you looking for a place to live?
