The Flame Ghost was a thousand-year-old monster who ruled the region before the Flame Cow King created the Flame Mountain with the Book of Flames.  Although his rule had continued for a long time, the appearance of the Flame Cow King shook the very roots of his rule.  The Flame Ghost was eventually defeated by the Flame Cow King.  Having lost his power and authority, the Flame Ghost turned into stone, torn to hundreds of pieces and scattered throughout the Flame Mountain.  This stone contains the venomous resentment of the Flame Ghost; a weak person would lose his mind simply by grabbing the stone.  A rumor has it that one can achieve outstanding effects when this stone is used as an ingredient for the cursed wine.
