"Die Regentrude" by Theodor Storm is a literary fairy tale written in 1863. When a terrible drought devastates the land, withering crops and parching livestock, an old woman recalls ancient stories of the Regentrude—a rain maiden who has fallen asleep. Two young lovers, Andrees and Maren, embark on a perilous journey into an underground world to awaken her. Guided by fragments of a magical verse and threatened by a malicious fire spirit, they must race against time to restore rain and save their community. (This is an automatically generated summary.)
