Quest journal

It looks like even Soyoung was thinking very hard to come up with ways to stop the great destruction or war when she's usually very quiet and timid. Listen to what she has to say more about this.

Dialogue

Offer: Soyoung (Core Alchemist)

Actually, I'm not interested in anything besides research, but it saddens me to see the monsters run amok, abnormal natural phenomena, and people talk about war all the time.

I think the situation has gotten worse as Undead Ground was known to the world...I wonder if we can prevent the Great Destruction and War if we purify the land of death.

Is there anything I can help you with? (accepts the quest)
No. There are more urgent things.

Yes.

Here, take this Stake.

Some areas of Undead Ground are marked so that you can drive in this Stake. Those are the spots that can stop the flow of death energy that surrounds Undead Ground.

I'm counting on you warrior. Please do that for me.

Receive the Stake.
