Intermediate dialogue 1
Keiran Thackeray: ''We've made up a lot of ground. At this rate, we'll catch up to Danthor soon.''

Miku: ''Then let's keep at it. The only forgiveness he will find is at the end of my blade.''

Keiran Thackeray: You know, you remind me of someone.

Miku: ''Really? I'm just me. Are you sure that it's not just that someone else is on your mind?''

Keiran Thackeray: ...

Intermediate dialogue 2 (Upon finding Danthor)
Miku: ''There you are, Danthor! Accept your fate and die in peace or die struggling in futility!''

Danthor the Adamant: ''Such tenacity. You still pursue me? It makes no difference, you know.''

Danthor the Adamant: ''His plans are already coming to fruition. What happens here will change nothing.''

Miku: ''Anything can change; all that's required is the will to do so. Let me show you mine!''

Intermediate dialogue 3 (Upon defeating Danthor)
Miku: ''At last... now the fallen can rest easier.''

Keiran Thackeray: ''It looks like some of the White Mantle escaped further into the Maguuma Jungle. What will you do now?''

Miku: ''I need to continue. This time, for myself. The question is, Keiran, what will you do?''

Keirain Thackeray: ''It's dangerous to keep on alone. I will accompany you.''

Miku: ''That's kind of you. I wonder, though. Maybe your kindness reveals that you rely on others too much.''

Keiran Thackeray: What do you mean?

Miku: ''Oh, I don't know. Is protecting me an excuse to keep on like this?''

Keiran Thackeray: Let's keep going; we don't want to lose them.

Walkthrough
See the walkthrough for Auspicious Beginnings for notes about playing as Keiran Thackeray

Head west through Majesty's Rest. Near where you found the Tarnished Emblem, you will again encounter Danthor the Adamant. This time, however, he will stand and fight instead of running away. Defeat him and his group to complete the quest.
