These are good criticisms. Again, how he came to be a sorcerer is something  I'd like to be revealed through the rp as the reveal will be detrimental to his character.

You're correct in a way. As SS he's  basically the gateway to the multiverse and can travel to where he needs to go by astral projection. Though I should've clarified that he's keeping our universe in check from the outside in by protecting its borders and not overstepping his jurisdiction. So he's not really a sheriff - more like border patrol in that regard lol.
