While other fairies amuse themselves in a fairy garden, Zemina and Farzana discuss how their mistress Ada, a half-fairy, has renounced her immortality to spend her life with Arindal, the mortal whom she loves. The fairy-king has set a condition which Farzana believes that Arindal will not fulfil even with the help of the magician Groma. Nevertheless, they get the other fairies and spirits to pledge their help in separating Ada from the mortal.
