Use the Empty Cliffspring Falls Sampler to draw a sample of water from the mouth of the cave by the falls. Deliver the Filled Cliffspring Falls Sampler to Alanndarian Nightsong in Auberdine, Darkshore.
The Cliffspring Falls in Darkshore serves as the principal source of drinking water for the region, and now I suspect it is the principal source of the poison that is harming the local fauna - deer specifically. Use this sampler to draw some water from the mouth of the cave; be careful, as dangerous naga now reside in a cave by the falls.
You're the one that the Cenarion Circle in Moonglade sent? That's wonderful! We've quite the crisis our hands here regarding the poor deer, and we're happy for all the help we can get.
Do you have the sample of water that Dendrite Starblaze said you'd have? He notified me that you'd draw one so we could work on a cure together...
By Elune, this water is disgusting! No wonder the deer are sick. Something is polluting the water, and in turn corrupting Darkshore's entire water table. Sick deer have been seen all over area, and not just by the river. While this water is most likely a primary source of the sickness spreading, there's something else at work here.
This water, believe it or not, will help us formulate a cure. While I research this water, I have need of some items to formulate a cure...
