I want you to cross the border to the human realm and fetch someone for me, brother.” I let out another bark of incredulous laughter and shove the jeans back into the satchel before dropping it on the floor. “Why the fuck would I do that?” “Because if you do, I’ll lift your banishment.”
Once he's over the border, he could just go off and live there, though. Unless the king has him make a bargain, where the magic would bind him in some way until he returns with the target.
