"Fine then, since you're so sure of yourself, and of our inability to stop you, I propose this," Sabynha wasn't sure if her would stick to his word, but in any case it couldn't hurt to try.
The vistani called upon her stage voice, and began, "First, we will all fight to subdue; no killing, and that includes you, giant. Second, your quarry will stay out of the fight, and you will not attack him. Should you defeat us, you must bring your quarry - alive and well - to Ragnar before you kill him. If you are so certain of your mission, surely your boss will not mind if you carry it out in front of him, and if you are wrong and we are right, then you've saved yourself the dishonour of the blunder you are about to make. In fact, we will even let you take all the credit."
When she was done, she paused a moment to allow the brute to consider the offer, then added some pressure to taunt him, "Will you agree to these conditions, or does your bluster only serve to hide the cowardice within you?"
