Voyslava sells her soul to Morena, an evil goddess, to obtain her aid in making Yaromir forget Mlada so she may have him to herself. In act 3, the shade (ghost) of Mlada leads Yaromir up the slopes of Mount Triglav to a pine wood in a gorge on top of the mountain. Mlada's shade joins a gathering of the spirits of the dead. She expresses in mime to Yaromir the wish to be reunited with him in the kingdom of dead souls.
