The main events take place in a remote province of medieval Prussia, Erta accidentally gets there, an empath girl, a professional fighter of a special galactic law enforcement service from a very distant future, as a result of a space-time conflict caused by a global galactic war, which brought with him to medieval land not only Erta, but also alien Beings, similar to small suns surrounded by clouds of emotions, also empaths. Something like a fantastic pseudo-historical courtly knightly novel.
