We could easily have held Silverwind Refuge from the Horde had they not taken control of our water elemental defenders on Mystral Lake.
One of their shaman summoned in Tideress, and old and angry water spirit of the forest who befouled our elementals and turned them against us. With the lake and the Horde pressing in on us, we had no choice but to retreat to the spire here.
Go east. Take the lake back so that we will have a chance to retake the refuge some day.
Since you must destroy the bracers to kill the elementals, it will probably be difficult to find the specific ones that contain the information the divining scroll needs. You can trade bracers with others in order to obtain the ones you need, or perhaps you have the divined paper already?
Well done, <name>, this should give us the information we need to have the culprit discovered. How would you feel about taking out the mage who fills our pools with corrupt elementals? The corruption of Ashenvale and beyond makes my stomach turn on its own--to have a wizard actively attempting to destroy it further sickens me to no end. We shall make him pay.
