Drossel, the heiress of the noble House of Flügel, lives in the Tower of Tempest, a castle that has been her family’s home for generations. She is cared for by Gedächtnis, a large, mechanical butler who has served the family for many years and who respects her late father. Drossel and Gedächtnis share a deep bond; they spend their days in conversations that promise intellectual depth, only to have their discussions interrupted by sudden, whimsical events that keep life in the tower lively and unpredictable.
