Pied Piper (Legend)

Origin
In 1284, while the town of Hamelin was suffering from a rat infestation, a man dressed in pied clothing appeared, claiming to be a rat-catcher. He promised the mayor a solution for their problem with the rats. The mayor in turn promised to pay him for the removal of the rats. The man accepted, and played a musical pipe to lure the rats with a song into the Weser River, where all but one drowned. Despite his success, the mayor reneged on his promise and refused to pay the rat-catcher the full amount of money. The man left the town angrily, but vowed to return some time later, seeking revenge. On Saint John and Paul's day while the inhabitants were in church, he played his pipe yet again, dressed in green, like a hunter, this time attracting the children of Hamelin. 130-160 boys and girls followed him out of the town, where they were lured into a cave and never seen again. Depending on the version, at most three children remained behind. One of the children was lame and could not follow quickly enough, the second was deaf and followed the other children out of curiosity, and the last was blind and unable to see where they were going. These three informed the villagers of what had happened when they came out of church.

Some stories suggest that the Pied Piper was in fact a demon or the devil himself.
