According to an old Russian folktale, the soldier returned home after fighting in a war. Near the end of his journey, the soldier began to exhaust his supplies. He met a strange beggar. Being a generous man, the soldier gave the beggar his last ration. The beggar sensed the soldier's generosity and gave away his Mystical Sack. He instructed the soldier it would catch any creature the owner commanded then the beggar vanished.
