Dialogue

Quest Acceptance

Runar: Done tending to the crops already? Very good. It should not be long before your room is ready.

Solemn Blessed: Runar! (Solemn Blessed runs up)   In the woods... <pant> <pant> Sin eaters. I fear they may have the touch.
Runar: Where!?
Solemn Blessed: In the grove to the southwest. For a mercy, they've yet to wander any closer to Slitherbough.
Runar: Then we have no need to engage. Inform the guard that no one is to set foot outside the village until they have moved on.
Solemn Blessed: But sir, what of Toddia's heartstone? It must be retrieved before the service.
Runar: Of all the times for sin eaters to appear...
Minfilia: Are you just going to leave them alone?
Runar: Under normal circumstances, we would not hesitate in striking the beasts down. But if they indeed have the touch, I will not risk them corrupting one of our own.
Minfilia: What was that you said about a stone?

Solemn Blessed: A few days past, Toddia, a child of the Night's Blessed, was slain by the sin eaters. We succeeded in retrieving her body, but in our haste, we failed to notice her necklace was gone. Strung to it was a pendant of jade─her heartstone. All of the Night's Blessed are given such a stone at birth. It is the most valuable possession one can own. It is custom to present the heartstone of the deceased at their funeral, as an offering to the heavens. But now...

Minfilia: What if... What if I could find it for you? I have experience fighting sin eaters. And the Light's...corruption does not touch me like it does others.
Runar: Master Matoya called you Minfilia, did she not? Are you truly the Minfilia? Descended from the Oracle? Even so, I dare not ask you to risk your life for the Blessed.
Minfilia: I understand how you feel, but I can't stand by knowing your people are in need and I can help. Please, let me do this.
Runar: Very well. But if the danger proves too great, you must retreat. I could never forgive myself if we were forced to hold a second service.
Minfilia: <gasp> I nearly forgot about Thancred. What if he returns before I do?

What will you say? Don't worry. I'll come with you. / Thancred doesn't need to know. -> Thancred doesn't need to know. 
Minfilia: Wh-What!? Do you mean to say...you'll come with me? Thank you. Let's hurry then, before he returns.
Runar: Go swiftly, and may the shadows keep you both.

Look around the destination

Minfilia: There! The sin eaters! I was hoping there would only be one...
Minfilia: There's no way we can search for the stone without dealing with them first.
What will you say? Let's get to it, then! / Perhaps we should split them up. / What do you propose we do?

Minfilia: Fighting them together here would make a lot of noise, which might attract beasts or other eaters...
Minfilia: But if we fought them separately and quietly, we might not have to worry about that. All right, then. I'll draw one away while you handle the other.

Speak with Minfilia

Minfilia: [Forename]. <pant> <pant> There you are. It's done. Though, I fear I was a bit careless. I'll do better next time, I promise. I... I'm fine. You needn't worry about me. More importantly, we have to find that heartstone. They said it was made of jade, right? I'll search over there in the brush.

Search for the jade heartstone

There seems to be no trace of the heartstone here.
You brush away the leaves and uncover a brilliant green gem.

Show the jade heartstone to Minfilia

Minfilia: Did you have any luck?

Minfilia: It's beautiful! This has to be it.
Minfilia: ...You know, Thancred always said you were a [man/woman] of many talents, and I think I'm beginning to understand what he meant. I have much to learn if I'm to be even half the hero you are. The hero she was...
Minfilia: Ah, I'm sorry. Forget I said anything. We should hurry back to Slitherbough. Runar and the others are probably worried.

Deliver the jade heartstone to Runar

Runar: Thank goodness you are safe. I had begun to fear the worst.

Runar: By all that is dark, you found it! We can proceed with her service as planned. These blessed gems serve not only to protect us in life, but to guide our spirits unto the sunless sea in the hereafter. Even should we be felled by the sin eaters, so long as these gems are recovered, our souls are ensured peace in the dark.
