Archmage Timear in Dalaran has foreseen that you must destroy 10 Centrifuge Constructs.
- Kill Centrifuge Construct × 10
It is into the Oculus floating above Coldarra that you must travel, <name>.
I have foreseen a situation in which you must destroy the centrifuge constructs therein. I can assure you that if you do not first eliminate these magical creations, you and your friends will fail.
Thus I have seen, thus you must do.
