The name "Rattenfänger" is taken from the legend of the Pied Piper of Hamelin (Rattenfänger von Hameln), who was hired by the townsfolk of Hameln, Germany, to rid the town of the rats that had overrun it. Unfortunately he is deceived and cheated of his payment, and he exacts a dreadful revenge on the citizens. The lyrics are in Latin, written in style of medieval poets, thinkers and troubadours/minstrels.
