The Leprechaun comes from a race of forest spirits (Leprechauns) that were in league with a king in the Dark Ages. They were summoned from the earth to protect the king’s gold and treasures of the Dark Ages from the clutches of greedy men who would try to steal it. Their ferocity was known throughout the land. When the king’s reign ended, all but one of the leprechauns went back to the earth.
