A potential option
I really don't like my home bank guy always telling me "you were the one who rescued such and such"
You could really expand on this, create arcane servant terminals, links to the atherium void, etc, etc.
Arcane energies, a tear of energy that stores my items (banker/merchant/thief/etc). Make a version that is terrifying looking and a version that is for weak-minded kneelers if you wish.
c'mon man, take my money!
It is the mind, that is the mind, confusing the mind. Do not leave the mind, oh mind, to the mind.
