Alli Allahis sacred order of the Magi
This piece is very old and has been wrapped in gold and turned into a pendant. This Agate was used in multiple magics by the ancient Alli Allahis order. These were priests of Persia. These priests were able to conjure in full flesh form the Djinn and the Djinn Slaves. This was but one of the magics they could do at will. Other occult related magic included the ability to change ones destiny at will, force love and power on anyone. You might ask why power but it was because they would be hired or retained for the ability they held.
What this does for you is it will give you the ability to bring forth the djinn you desire. This will also allow for you to force whatever magic you need to to on someone else with out waiting for any type of spell to work. This force will stay until you remove it if you decide to. A word of caution is that when using this for that it does take away the free will of others. The magic being that strong is why they were such a sacred and secret group. This piece is rare and the only one I have.
