Gottfried Stommel incorporated great parts of the Goethe fragment (Magic Flute part two) and completed the story.
Act I
Pamina and Tamino are parents of a son. Monostatos on order of the Queen of the night has closed their son in a golden sarcophagus to make him die. Though Sarastro recommends to always move it to keep the child alive.
On the ritual of the priests one of them has to go to earth and the ticket falls on him.
Papageno and Papagena receive golden eggs from Sarastro and children come out of them. Their daughter Aurora is already 15 years old.
Act II
Pamina wants to build a Mausoleum for the sarcophage and dedicate it to the sun gods. Sarastro -undiscovered- meets the Queen of the night during his pilgrimship. First he convinces her to join the initiated people but then she insists to kill Sarastro because of a hundred-year-long tradition of her revengeful family. Sarastro makes the deal with her to save the child and she gives him the poison.
Act III
Aurora then can free the enclosed child by the carillon of Papageno. His name is Phoebus and they unite in love. In Tamino´s palace they marry as the funeral procession of Sarastro passes. The Queen appears but after a first triumph she breaks down repenting her paranoia. She dies at the catafalque and rises to heaven together with Sarastro.
