Don't Drink the Water

Our shaman claim that the elements of water have become greatly agitated by the pollution of the water source. We know that the Exodar's power core is lodged into the mountain to the west. It must be leaking volatile fluids into the water supply! I need you to get me more information.

<Aesom points to a flask and nods.>

You are to take this flask and follow the beach north until you reach the area where the rivers of Bloodmyst drain into the ocean. Take a sample from that location and return to me.
