Rozhok from the Kunstkamera

​Origin
The Kunstkamera was the first museum, a "cabinet of wonders", in Russia, created by Peter the Great to house and display special objects and specimens. As was typical of the time, he collected people with strange physical abnormalities, or mutations, or at times just their body parts, and either had them kept in the museum or installed in his court as guards, servants, or entertainers. This accordion was used by one of Peter's courtiers to "find" new freaks to add to the Tsar's collection.

​Effects
When played anyone who hears the sound of the acordion clearly, except the player, will begin to mutate. Mutations are random, as are the extent to which individuals mutate. Some gain minor abnormalities such as heterochromia or polydactyly, while some transformations become monstrous, sometimes even altering the victim's mind and making them lash out violently.

Even after the accordion has been neutralized, victims will not automatically be returned to normal, and so far none have been successfully returned to their original state even with artifact assistance.
