Walkthrough
After taking the quest, you must use 1 Transmogrifier Tonic or the everlasting version before speaking to the Voice of Grenth. You can get tonics from Trick-or-Treat Bags or trade for them.

Skills
During this mission, you are an Agent of the Mad King and have 600 Health, 40 Energy, 4 Energy regeneration, Consumables will not provide energy or health increase, but will provide a speed boost, which can help.

When in Underworld, follow the yellow map pings to King Frozenwind and use the skills to distract the enemies. Save The Mad King's Influence for the Coldfire Nights as they'll hex you even when you have a speed buff. Do not attempt to go directly to the marked area, you must traverse the Wastes area of the Underworld in order to reach an area surrounded by Ice Elementals. They will not be hostile. Talk to the king and the quest is finished.

Initial dialogue
''I am the steward of Mad King Thorn, and I do his bidding. My undead liege has sensed foreboding tremors in the Underworld. He has also sensed seasonal baking in Royal Chef Culwich's kitchens, but I have already volunteered to investigate that. Milord's senses are selective but keen. This new intuition also requires attention. That's where a brave and skillful adventurer like you comes in. I would like you to act as an emissary of Mad King Thorn and go talk to his royal ally, King Frozenwind, who guards the Hall of Judgment. King Frozenwind may be able to shed some light on this mystery. We certainly hope it's nothing so troublesome as that Dhuum business from last year.''
 * Mad King's Steward

''Anyway, travel quickly to the Underworld by speaking with the Voice of Grenth. Make sure you use a Transmogrifier Tonic so that the Voice recognizes you as an agent of Mad King Thorn. As this is a diplomatic mission, you must go alone. After you've talked to King Frozenwind, report your findings back to me. I'll see that you are well rewarded for your efforts.''

Intermediate dialogue
If not affected by Avatar of Sweetness:
 * Voice of Grenth
 * I was told an Agent of the Mad King was coming. You don't look much like one...

If affected by Avatar of Sweetness:
 * An agent of Mad King Thorn wishes to enter the Underworld alone? Very well, if you think that's wise. The Reapers have gained some degree of control over the Underworld at the moment, so now is an opportune time to travel, relatively speaking.
 * ingame I'm ready to travel to the Underworld. (sent to The Underworld)
 * ingame Sorry, I don't do deja vu.

''The emissary of the Mad King arrives! It is good to see you again, despite the circumstances. Or was that another who visited my hall last year? I am sorry, little one, but to me you all look similarly scrumptious.''
 * King Frozenwind

''Your lord is correct: dark things still stir in these depths. It is Dhuum, candy man! Death inevitable is not so dormant as we believed. Let me tell you the tale again in case it has not stuck in your mind.''

''Long have the bards sung of Grenth's defeat of Dhuum, the former ruler of the Underworld. With the help of the rebellious Reapers, Grenth usurped Dhuum's throne. But the books and songs only tell part of the tale. You see, Dhuum was not fully destroyed; Grenth was simply not powerful enough to slay him. Instead, he forced Dhuum into a state of dormancy and imprisoned him within the Hall of Judgment, trapped behind massive enchanted doors and layers of divine magic. There Dhuum remained slumbering...waiting. But his torpor is not so heavy that Dhuum does not occasionally wake.''
 * ingame Why does he continue to wake? Is a little sleepwalking really that harmful?
 * Dhuum awakens fueled by dark powers, eager to reclaim his seat as The Final Judge, and set to cull the life from those who cheat death. Every time a creature in the Underworld dies, the release of life energy adds to Dhuum's vigor. Too many beings are being slain in the Underworld. Dhuum grows both strong and restless. I fear that one day he will come to his full strength, and then those doors will not hold. Where Dhuum walks, candy man, no soul is safe! Go, tell your master to heed my warning: Dhuum remains the most serious of threats!

Reward dialogue
''Dhuum? The Ender of All? This is...unexpected information, but you have delivered what I asked for. I doubt Mad King Thorn will believe this matter wasn't fully dealt with last year, but Dhuum and his promise of death undeniable should not be ignored. If he were to seize control of the Underworld, it would be disastrous. The fundamental rules of life, death, and undeath would change...a state of affairs that would be unacceptable to a spirit lord like Mad King Thorn. Thank you for your service, mortal! I will bear this grim news to my liege so he may plot his next move. I fear for us all...''
