This piece conjures the magic of the Royal Djinn of Persepolis. These entities were commissioned by Darius I, for whom the Palace at Persepolis was built. He ordered a very powerful sorcerer to create a series of one dozen djinn to keep watch over the palace.
We were able to summon one these djinn who we set into this piece. When you use this piece you can also conjure this djinn. He will grant a total of 21 wishes, which is evidently a sacred number, I guess because it's 3x7 Either way, he will also blanket you with white light power that will give you divine protection from evil forces, darkness, spells of malice, etc.
