The ocean- forever changing like the tides.

Low tide uncovers the nasty seaweed, broken shells, treasures lost to never be discovered again but to be stolen by the causal visitor stopping to gaze at it's beauty. High tides raising to spill into the empty caverns bringing fleeting life and calm.

A multitude of colors changing with the atmosphere and location. Temperatures to comfort all those who care to dive in but the deeper they go to enjoy what drew them there in the first place the colder and darker it becomes.

It's also filled with wondrous beauty and life. It gives and swallows you whole depending on what you're looking for. You can't be 100% sure where the currents begin or the forces that cause it to change.
