Ivan III of Russia
After seeing a spy lurking around his house in Ukraine, Andrew Charnetski hastily removes his family to a safe location. While away, Peter of the Button Face, acting under the orders of Ivan III of Russia, burns the Charnetskis' village to the ground in search of the "Great Tarnov Crystal", a mysterious Tarnov crystal that has caused many wars over the millennia and had, a few centuries previously, been entrusted by the city of Tarnów to the Charnetski family for safeguarding until its discovery by others, at which time it was to be given to the current king of Poland.
