Here is what I wrote for the Magician:
The Magician has golden tattoos on his arms and shoulders representing the golden solar energy that he is (Will). There is a red halo behind his head and I have no idea what it is, an aura of his energy? Another interesting element is the box that is under the skull, it is closed with a lock and you need a key to open it. What does the Magician hides there? Our hidden potentials? I’m guessing he is the only one who can open it.
