Emissary of Asheron tells you, "I have been unable to destroy this device. Aerbax realized what you were doing and protected his last device somehow."
Emissary of Asheron tells you, "However, I have studied the device and believe there is a way to use it's resonant magic field."
Emissary of Asheron tells you, "Scouts report that Aerbax's forces are even now attempting to repair the other devices you destroyed.
