Also... I encountered someone, while taking the liquid from the vat. A floating girl. She was small, and was wearing a black hood.

...she told me she'd answer my questions if I could catch her... but I wasn't able to.

She said... ah... "Still thinking you'll stop what we've started? What a fool. You're not the first person whose tried to play hero. You won't be the last. You'll fail just the same, you stupid brat!"
