Dialogue
 * "A new face then, is it? Many things are changing these days... to see a body of flesh and blood walk these lands is certainly a surprise. Something new stalks these lands. I know not what they are, but I know that they have caused me to fear. They must be destroyed. Will you seek them out?"

Intermediate Dialog:
 * Abaddon's Adjutant: "The armies of our Lord gather to cleave those lands asunder. Can we count on the assistance of your master?"
 * Emissary of Dhuum: "Dhuum has offered his aid to Abaddon's cause. Do not take his word lightly. You will have the forces that you require."

Walkthrough
Follow the quest markers to destroy the demon groups. When you finally get to the rendevouz point of the two messengers, make sure to clear any Torment Demon patrols around, otherwise they will make the fight very difficult. When fighting the two messengers, make sure to take out the Emissary of Dhuum first as he is a Dervish boss capable of spiking multiple party members for great amounts of damage.

Trivia
