Imagine the Pied Piper of Hamlin being a really, really, really evil creature, far more so than in the movie version. He uses other people's thirst for revenge or domination to spread the death and chaos he seems to love. This he does a lot of in this volume.
In addition, there's the Pied Piper of Hamlin story from Grimm Fairly Tales #12, some character designs and issue 0 of 1001 Arabian nights.
