You come down here in my own home, uninvited, to bother me? I can't decide whether you're brave, or just a fool. You humans surely can be such pests sometimes.

(You explain the situation to Carta, going in depth about Albatross' strange behavior and how Muse thinks they may have been cursed.)

A cursed bird? You really think that such nonsense is worth my time? What good are those zoo keepers if they can't even take care of their own animals? Besides, I know nothing of curses, my expertise is in fortune-telling.

(You keep pleading to Carta for her assistance. The poor little Albatross did nothing wrong, their only fault is being too adorable!)
Ugh, enough already... I... do suppose I possess a wisdom unmatched by any of those Aquarium folk. I have many old tomes lying around here, I'm sure one of them could be of use.

(You watch as Carta fumbles around the piles of books she has laying in the corner of her cave. She picks up a book covered in dust and thumbs through the pages.)
Ah, perfect. This is exactly what I need.

Alright, I will agree to examine the bird, but this is something I cannot do alone. As dictated by this tome, we will need to prepare a special cleansing potion, and judging by its requirements, it will be no easy task. So? Is your love for that little bird strong enough to accept such a task?

Hmph, very well. This is what we must do: first of all, obviously, go get that bird from Muse and bring it back to me.
The potion we're about to prepare is rather unique from the looks of it, because its ingredients are not items you can find here and there on the seafloor. We need the wandering souls of monsters.

In order to obtain souls we need to release them from their physical forms. I want you to hunt the following: 999 Bone Fishes, 999 Gobies, 499 Squids, 499 Risell Squids, 499 Sharks and 499 Cold Sharks. Once you're done with your task, you and the bird can come back to me. Don't look so surprised, I told you it wasn't gonna be easy, didn't I? Now go.

Well, I can't say I'm surprised. At least you're not a complete and total fool.

Finally, you're back. What took you so long, hm? Was Muse reluctant to let the bird go? Anyways, it looks like we're ready for the next step. Talk to me again once you're ready for something actually difficult.
