I had hoped that the Nexus' impact was limited to this region. Recently though, reports have flooded in from all over Azeroth suggesting that geologic instability is growing exponentially!
I need the Nexus monitored regularly as I work to develop a solution.
I've placed sensitive instruments around Coldarra, disguised as Malygos' scrying orbs. One lies in the trench near the Nexus, and three are hidden in the structures around the valley's perimeter. Visit each and return to me with their readings.

Have you read all of my instruments, <class>?
Completion
This is worse than I expected.
Malygos is channeling too much power to this place. If he's not stop, Azeroth will be the next Outland! Fortunately, I believe that I've engineered a temporary solution....
Notes
There are 3 structures around the perimiter of the Coldarra area (a 'caldera'). Just inside the ground level entrance of each lies one of the orbs. The Nexus orb is a little way counterclockwise from the Nexus Meeting Stone.
