'There is no sense in delaying what must come. There must be a parley. I will go forth with a small group of my most trusted allies and call for Sauron's surrender. I would be honoured if you would accompany me, my friend.
'I do not expect the Dark Lord to give in to our demands, but still I must offer him the opportunity. Speak to me when your preparations are made and we will go together.'
