Tomorrow is a Water Palace

Sybille is the last living person on Earth, a planet that has run out of water as well as out of history. She roams through arid lands in order to find water, traveling through strange visions. A vision that lives within a vision, the water of waters may live in her womb. Entities that have more memory than human beings try to communicate with Sybille. How will she manage to persuade the spirit of water to come back to Earth?
