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, an 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.
