'Faramir has asked me to continue studying the waters of the Morgulduin, but I have yet to learn what might be causing this corruption. You helped me retrieve river samples once before, might you do the same again? I am certain we will find the answers if we work together. Does a tributary passing through the city taint these waters, or does the problem lie near the river's source? Would you take water samples from nearby tributaries into the Morgulduin and a sample closer to the river's source for me? I would be most grateful for your assistance, my friend.'
