Introductory Dialogue
Dialogue with Henkoff
 * "It was you, wasn't it? The one who killed the heathens that attacked the people... At that time, while you were battling those heathens, we received information that a party was moving covertly to the Undead Ground.
 * According to the witness, the party appeared similar to the infamously brutal Vampire mercenaries...
 * Though the very fact that they still remain is a serious problem, the larger issue is that the one who disappeared after leading the coup d'etat, the Thieves Guild Master Kashu, was seen among them. As I heard that one of the guards witnessed this directly, go and ask if you wish to hear more details."
 * Options:
 * [Go speak with the guard, Miles.]

Intermediate Dialogue
Dialogue with Miles
 * "Ah, are you speaking of those pale people? Those scoundrels with the cold aura that appeared almost as if they were made from the sculpting of ice... And, as you know, I am familiar with the Thieves Guild. Kashu was definitely among them! My eyes do not lie.
 * I can even distinguish if a bird flying by has had a bath or not!
 * However, those scoundrels entered into the Undead Ground, as dangerous as it is. Noone who has ever gone there has been said to make it out alive...
 * What are they planning to do next? I just wish that it will not have a serious impact on us...
 * By the way, did you know?"
 * Option:
 * [What?]
 * "That it suddenly seems that the demons are fighting one another of late. here and there, it's just utter chaos... Are they of sound mind?
 * Are there any demons that could fight those thieves? There are demons like the Ghost around the Undead Ground. It would be nice if they could kill those scoundrels.
 * Then we could find comfort... Don't you think?"
 * Option:
 * [Go back and report to Yuan.]

Completion Dialogue
Dialogue with Yuan
 * "Kashu has resurfaced...? Toward the Undead Ground...?
 * Though I knew that he established a tie to the Vampires of the Dark Clan, his entrance into that dangerous place seems to clearly indicate that something new is being planned."
 * Option:
 * [Then, what if we were to cooperate with the Undead?]
 * "What? Cooperate with the Undead? With demons? Hmmmm... The enemy of an enemy... It would appear to be an excessively dangerous proposition...
 * It would be good if my master were here at times like this... I must think about this.
 * After all, actoing with haste may precipitate an even larger issue coming about.
 * Would you go and wait?
 * Option:
 * [Alright, contact me]
