Protect the Water Source
What to kill and where to find the goals.
One-off: the reward is given once. If you are levelling in this zone anyway, it is worth collecting what it needs along the way and closing it.
This is an exchange chain: the reward is collected as items traded at an NPC — the shop's full stock is not laid out here.
Story
I don't know if you've noticed, but the Mother Tree in the middle of the village has been slowly withering. The progress of the blight is so slow that it is hard to notice unless one possesses high magic powers. We do not wish to worry our brothers, and only a few of us know this secret. None of our ancestors' records show any incident of the Mother Tree withering. I cannot shake the dread that something is terribly wrong.
As a result of my research, I discovered that the Mother Tree is withering because the water is full of contaminants that dry up the tree's roots. It is my guess that someone is polluting the water source of the river that flows into the village.
But I cannot guess who that someone is. That someone would dare to pollute our life source, our water, in this chaotic time of war against the Misty Mountain orcs ... This cannot be left alone, it must be dealt with. The sentinels cannot be spared, as they must defend the village, and all of our Rangers have been sent to the woods in preparation for our battle with the orcs. You must go to the water source and find out the reason behind the pollution.
You can reach the water source by following the river that flows into the village and travelling north. If you find anything that is even slightly suspicious, please investigate it. And bring back proof so that I can examine it.
Take this charm. It will protect you from the contaminants that have fouled our water. Please hurry. May the blessings of Eva be with you ...
Quest steps
Elven Hierarch Asterios is concerned that the Mother Tree of the village is being contaminated. He asks you to visit its water source, the lake north of the village. Destroy the cause of the contamination, the plague zombies.
Collect: Plague Dust × 1
You've obtained plague dust from a suspicious looking zombie. Could this be what Hierarch Asterios was talking about? Take it to him.
The dust from the zombie's flesh has been the cause of the contamination. A large amount of the dust is needed to perform a purification ritual. Hunt the Plague Zombies.
Collect: Plague Dust × 999
You've obtained enough plague dust for the purification ritual. Deliver it to Hierarch Asterios.
