Infernal Khorugv or Cossack Christmas
Cossack family exists in the world as long as it is born Cossacks-knights who defend their land from enemies-conquerors. And to the Cossacks who laid the heads in fight, all sins are forgiven. Enraged by this, the Devil makes a bet with St. Peter,
who will be able to capture and hold until Christmas the best and bravest Cossack Semyon. So the Devil will be able to destroy the entire Cossack family on earth. But the brave Cossack is not affected by the spell and it is impossible to intimidate or buy.
