Dialogue
 * "Ahai, . I have just received grave news. Servants of the fallen god Dhuum have been working with Abaddon's minions for some time. But the servants of Dhuum have recently been seen near a strange tomb in Nightfallen Jahai. If you've been out there, you know Nightfallen Jahai is rapidly changing to resemble it's [sic] counterpart in Elona. As the planes grow closer together it will become possible to open portals between the worlds and cause the real Jahai to fall into night. I fear the history of dark magic associated with this tomb will allow the Avatar of Dhuum to open such a portal to the Jahai Bluffs and stage an invasion. Someone must journey to the tomb and put a stop to this invasion."
 * Accept Dialogue
 * This definitely bears investigation.
 * Reject Dialogue
 * I still have nightmares of my first trip through the Jahai Bluffs.

Reward Dialogue
 * "Well done, . That's one less fallen god Elona must worry about. But, I fear the battle that still lies ahead of you will be quite a bit harder. Perhaps this will help in your quest to defeat Abaddon."

Walkthrough
The Emissary of Dhuum is a short trip northeast of the Gate of the Nightfallen Lands. He waits by a statue all by himself, and as a single level 28 monster he dies quickly. But don't be fooled. If you approach to within melee range, groups of demons appear. Fortunately they are closely grouped and so area attacks work well. Use party-wide protection spells and chants and have fighters keep the groups of enemies penned in and away from the healers and casters. However, you only have to kill the Emissary to complete the quest. If you spawn the mob, kill the Shadows of Fear quickly, or you get more Horrors than can be handled easily--assuming the Fears spawn (they don't always do so).

Even easier, bring a longbow or flatbow and kill the emissary at range--use poison and ignite arrows to make it faster. Keep your group pinned back (or put on passive) so they don't aggro the mob. The Emissary will not even move as you kill it.

You can easily lure the Emissary away before the group spawns. Send you henchman/heroes back. Walk into aggro range, attack him with a staff or bow and then run back. You will have enough time to get out of aggro range of the mob.
