An old man journeys across a morphing sea as he wishes to return to the beginning of his journey, which he believes spans centuries and even millennia. Proteus remembers when the first element, water, first allowed the sea to take on various forms. He hears the song of time, which he believes will prevent the sea from posing an environmental threat. Proteus remembers seeing the sea change for the first time all those years ago, and he aims to recapture this moment.
