Arramor listens to Marcus's symptoms, and (assuming he makes the relevant Heal and Spellcraft checks) says:
"Marcus, it appears you have been struck with blinding fever a rather nasty disease. It doesn't appear to be natural, but rather magical. Unfortunately, I am unprepared to deal with it at this time. I will pray to Tyr for guidance on how to treat this affliction."
"We should talk with our guests here to get some more information on who we are dealing with. Arramor, I think you should talk with them. If they don't answer you then they will answer to Cramp [intimidate]."
Arramor smiles at Marcus. "Hopefully, that won't be necessary."
Turning to Zoya:
"Zoya, I have honored your request, your mate shall live. Zoya, I am faced with a big problem. I cannot hold you captive. I do not have chains big enough to hold you. I do not have enough men to make sure you do not escape. I cannot hold you. Ordinarily, I would let you go on your wordbond that you would never face me again. This is what I would do, but the sky chiefs have told me that I must make sure that all offlanders leave this world. This is what I gave my wordbond to the skychiefs to do, and this is what I will do. I should kill you and your mate, to ensure that my word to the skychiefs is fulfilled. I should kill you and your mate so that you do not betray my brothers to our enemies. But, you have asked for mercy, and have given your lives to me with honor. In my tribe, it is my right to take you as thrall. We are not in my tribe however. I offer you this. Follow my shield true, and I will pay you and your mate your contract when we return to the skychiefs. Follow me, and I give you the protection of my shield to my last breath, I will not fly away and leave you to die as did the gnome. Betray me, and I will give my last death to see you die. This is my word, and my oath, which I shall back with gold. Now Zoya, you and your mate must choose, put your life under my shield, or onto my sword. I shall honor you either way, but you must choose."
Arramor draws his sword and offers his shield to illustrate the point and waits for Zoyas answer.
