A common occurence in the 13th century, was that homeless children would train rats, making them perform various tricks, in order to get money to live.

The rats often could jump, roll, somersault, and even more, but for the most wonderful trick of all, the child would tie the rats tails together, and the rats would skillfully untie them.

This went on for a few decades, with new children teaching new tricks to new rats, but none of the tricks being as impressive as the tail untying.

One day, a rat taming child arrived at a popular village of eastern Europe. She displayed her rats, and their tricks days after days, but not the best one, planning to leave it for last.

Unfortunately, a few days later, an illness plagued the village, and many people died from it. Due to the disease carrying nature if the small rodent, the girl's rats were blamed, and the townsfolk had decided to execute her.

Pleading for her life, she manage to make a deal with the people, if she could prove that her rats were under control by performing the tail untying trick, she would be set free, and allowed to leave the town. If not, her, and her rats would be executed.

She made all the necessary preparations, and ordered her rats in a masterful manner, but when came the moment to untie the tails, the rats did not perform as expected.

She was utterly defeated in front of this unexpected turn of events, and was powerless as the townsfolk dragged her to the town centre, and killed her, followed by cheers and cries of joy.

The rumor that rat taming children were spreading disease, spread itself, ironically, faster than any pathogen. In the whole civilised world, people were killing those children.

It is said that now, their souls wander in search of rats who can perform this trick. Sometimes, for no apparent reasons, rat will jump around, roll around, and do all sorts of tricks, before having their tails tied together. Sadly, they always fail to do the trick and free themselves, and end up dying of hunger, unable to get away
