The young woman who stands next to a cage which contains the known Universe is called Nature. She thinks Creation into existence, manifold and beautiful as shown in the mass of flowers that emerge from her veil. Her expression is rather sad and her gaze turned inwards, because dunes of yellow sand are slowly advancing, and with it a dark beast and its master who intends to rule and to enslave the world. The nightingale calls out loud and clear, but it needs to be seen if Mankind will heed her warning.
