Honor the Dead

Five of my best field agents were assigned the Marris case. One returned, only to end up dead in his sleep three days later. What little information we did manage to get out of him was incoherent gibberish. We made out two words: "Nathanos," and "Blightcaller." I do not have the available manpower to continue this investigation and Ravenholdt will not assist us. We must get to the bottom of this; if only to provide closure to the families of the deceased. Will you help?
