Worshiper under the Moon - Fox Grass

After being Ice Bound for a thousand years, this piece of meteoric iron seemed impossible to be smelted down however hard the imperial craftsmen tried. Until one day, a junior apprentice accidentally exposed it to the moonlight. A miracle took place at that very moment. The meteoric iron melted into the form of Mercury, giving off a dazzling glow under the moonlight. Some of the meteoric iron splashed on a strand of the nearby Fox Grass, giving it a holy power to ward off evil.
