Report to the Image of Archmage Modera near the City of Dalaran.
I bring ill tidings from Dalaran. Something has disrupted our ley lines, causing erratic and destructive behavior from our constructs in the city.
We know not yet what is causing this mayhem. The high council has ordered us to keep this matter private so as to not bring shame to our order. But we cannot keep up this charade forever. The city is being overrun as we speak!
Archmage Modera has dispatched me to solicit outside aid. Seek her image out near Dalaran beside Lordamere Lake.
