Kurai waited until the king had left the room before he gave into a violent coughing fit, his eyes widening as he saw that he had coughed up blood and he felt Nila jumping from his shoulders, "Master! Are you alright?"
He frowned, "Why did I-", but he was interrupted by Aether, "That is the backlash I spoke of. Luckily you had only intended to grab her so the backlash is minor. If you had attempted to knock her out and failed, the backlash you would have received would have been much worse."
Kurai wiped his mouth with his sleeve, feeling a little shaken, "Why does it work that way?"
Aether shrugged, "Because when you use my power, you invoke the power of order and justice. Once it's invoked and the path is set, it reads your soul, and any hesitance or pity you may suddenly feel toward the target or even missing the target will cause the ability to backlash onto you, as you had been the one to invoke it and yet you then stopped it from completing its task."
