Listen to the conversation between Marni and Tori.

Quest Text What a troublemaker you are!

Summary Tori! Did you forget that research materials
should always be handled with care?
They're precious! What if you break them?!
It wouldn't have been worth bringing you along then, would it?
Ugh, I'm sorry, Doctor...
Bu.. but I hate corpses so much!
Aaargh! Argh! Was that screaming?
Aren't corpses supposed to be dead?
Hm? Oh, Adventurer.
What did you come here for?

Summary As you can see, we are investigating this frozen corpse.
As far as I can tell, rot has yet to set in despite it being dead for several years.
No matter how cold an area may be, corpses tend to show
some signs of decay after a few years have passed.
Could it have anything to do with the ice here?
Or is there a special chemical coming from nearby?
Well, whatever it may be, my new goal is to investigate this corpse and the
surrounding areas so that my own specimens may be kept from decay.
But tell me. What new excitements have brought you to
this cold and distant place?

Summary Now this is very interesting, isn't it?
Where did you get it?
Ho-oh, the Okjinsini's Flame of Origin...
I had hoped to research that one day.
A mysterious flame that grants new life even in death...
It's only natural to wonder how such a thing might work.

Summary Are you looking for this?
It was under my foot... What a strange-looking thing.
