Buddha's Mystical Staff

Many years ago, Buddha set up the eternal cycle and each year his sacred staff would be passed to one of the 12 Zodiacs. The Zodiac who holds the staff would spread his will over the world for the full year, which provided a balance to all things. If demons get the staff, they would use it to spread evil. Each year the dark monks try to obtain. The only time that a demon could take the staff is in the 12 hour window when the Zodiacs gather to pass the staff.
