— I see, so you want to go back to the surface. It’s simple: I’ll give you a tattoo that will serve as proof of your oath not to reveal the secrets of this place. If you start telling anyone about its existence, your heart will stop, and nothing will help you, not medicine, not magic. His Lordship pays for this service, so I don’t need any money from you, just your consent; otherwise, I won’t be able to complete the ritual.
