"Sign this, I will help you, or else you are alone with this," Auriel said as he dropped the paper on Kira's face and took the metal wire around her neck, coiling it around his wrist.
"What is this?" Kira asked curiously as she looked at the paper.
"A contract artifact. If you sign this with your free will and break your words, you will die, if not, you will live." Auriel explained.
This artifact was a one-time use artifact that didn't work on someone more powerful than the user. So, while Auriel was Master and used this paper on a Grandmaster, it would be useless and a waste of resources.
"Does this work both ways?" Kira asked with fascination in her eyes and she bit her thumb hard though to draw blood and drop onto the contract artifact.
"It does," Auriel said. "But I am stronger, so at most, I will get seriously injured. So do something idiotic while knowing this. You will die but I will just get injured."
