Battle of Reality and Deception
The following is recorded in the Video Archive
"Battle of Reality and Deception"
Video Summary: Villains always have ulterior motives, which is quite normal, right?
Story Description: Camille, representing the Exaltist, negotiates with Hartman over the Sacrifice Core. While both sides are feeling each other out, we've decided to take a shortcut and intercept the Core first.
- Camille: Where's the Sacrifice Core?
- Hartman: Camille, you really think I'd stroll around with something this important?
- Hartman: Plus, even though the Ravenlocks and the Exaltists have been working together for ages, I've hardly even met Lady Dina.
- Hartman: I'm the one offering the Sacrifice Core here. I'm curious what Lady Dina's got lined up for me in return.
- Camille: I'm just here to verify that the Core you mentioned is real. Once that's sorted, Lady Dina will give you a proper response.
- Camille: Our partnership isn't just talk. We need to be sure you have what we need before moving forward.
- Hartman: Sure thing. I'll take you to where I keep the Core.
- Hartman: Once you verify it's legit, have Lady Dina come over. We'll lay everything on the table face to face.
- Camille: Alright, lead the way.
- Vivian: It seems Hartman is trying to bargain for more. What a greedy and insatiable man!
- Vivian: It's just that... why would they only send Camille for something as important as the Sacrifice core?
- Vivian: And I can't shake the feeling that Camille doesn't want Hartman and Dina to meet. Why is that?
Who's Dina?- (ProtagonistProtagonist): (So, this Dina they were talking about... is she the leader of the Exaltists?So, this Dina they were talking about... is she the leader of the Exaltists? /
Who's this Dina he just mentioned? Is she the leader of the Exaltists?Who's this Dina he just mentioned? Is she the leader of the Exaltists?) - Vivian: Um... kind of...
- Vivian: Lord Phaethon, I really think we should hurry. We must get to where Hartman keeps the Core before anyone else does.
I've planned the route already.- (ProtagonistProtagonist): (I've mapped out a shorter route, but there will be Ethereals along the way. I'll leave the fighting to you, Vivian.I've mapped out a shorter route, but there will be Ethereals along the way. I'll leave the fighting to you, Vivian. /
I've got a shortcut planned, but there are gonna be Ethereals along the way. I'll let you handle them, Vivian!I've got a shortcut planned, but there are gonna be Ethereals along the way. I'll let you handle them, Vivian!) - Vivian: Don't worry, Lord Phaethon. You're in capable hands. I'll ensure your safety.
- (Enter Combat)
- Vivian: Ethereals! Stay away from Lord Phaethon!
- (After defeating all enemies)
- Vivian: Looks like Hartman's trying to negotiate for more leverage...
- Vivian: Let's get out of here before we're spotted.
- (After defeating all enemies)
- Vivian: Let's keep moving, Lord Phaethon.
- (Enter Combat)
- Vivian: Leave the enemies to me, Lord Phaethon!
- (After defeating all enemies)
- Vivian: They're still over there, looks like they're arguing...
- Vivian: This is our chance, let's hurry.
- Vivian: No matter who has the Sacrifice Core, Hartman or the Exaltists, it would be really dangerous.
- Vivian: Our best move is to seize it before they do and destroy it.
- (Reach the top floor)
- Vivian: Hand over what's in the box.
- Vivian: Or we do this the hard way.
- Hartman's Subordinate: You sure talk big, little girl.
- Hartman's Subordinate: Let's see if you can get past me first!
- (After defeating all enemies)
- Vivian: Let's hurry and secure the Sacrifice Core!
The Missing Core
The following is recorded in the Video Archive
"The Missing Core"
Video Summary: Empty... It's empty!
Story Description: After reaching the target location, you discover there's no Sacrifice Core in the box.
- Vivian: Lord Phaethon, the box is empty!
- Vivian: So Hartman never kept the Core here to begin with?
- Hartman: How did you even find your way here?
- Hartman: Where's the Core in the box? What did you do with it?
- Camille: You call this keeping the Sacrifice Core safe?
- Just as everyone stands confronting each other, a voice comes from behind...
The Exaltists and Dina
The following is recorded in the Video Archive
"The Exaltists and Dina"
Video Summary: "Vivian, it's been ages."
Story Description: Dina makes her appearance, revealing a part of Vivian's past and pointing out that the Sacrifice Core in Hartman's possession is fake, and that the real core's whereabouts is unknown.
- Dina: Vivian, it's been ages.
- Vivian: Dina!
- Dina: Oh my, you actually remember me? Aw... so sweet.
- Dina: Look at you, thriving! I thought you'd totally forgotten about our past.
- Dina: So, tell me. Do you ever dream about the people you've killed? Are they crying in your head all night?
- Vivian: Back then, I had no idea...!
- Dina: You had no idea? While you were soaking up all that love from daddy and everyone else, you had no idea what was going on?
- Vivian: I—I wasn't...
- Camille: Lady Dina, Miss Vivian didn't actually...
- Dina: Camille, when did I say you could meet up with Hartman today?
- Camille: I... I just wanted to make sure the Sacrifice Core is legit. I was worried Hartman might try to pull a fast one on us...
- Dina: Really? So loyal! I thought you'd be more like the old days...
- Dina: Just a few words from Vivian, and you'd be plotting my demise, just like what you did with Father.
- Camille: I won't, Lady Dina.
- Dina: Don't even think about betraying me, Camille. You owe me for what went down back then.
- Dina: However, I do understand your worries. This core...
- Dina: It's fake.
- Hartman: No way! I got this straight from Hugo! It can't be fake!
- Hartman: How can you just claim it's fake without any proof?
- Dina: Ugh, seriously?
- Dina approaches Hartman and coldly inserts the Core into an open wound on one of his subordinates.
The guy collapses to the ground, screaming. Dina wipes her hands and casts a look of disdain. - Dina: The Sacrifice Core can max out the Ether particles within human bodies in no time at all.
- Dina: But look at your little subordinate. How uncouth. He's making noises like some animal. Can you shut him up? So annoying!
- Dina: The masterpiece Father made for the Creator isn't this worthless piece of junk you're holding.
- Hartman: So, the real Core...
- Dina: Vivian, where do you think the Sacrifice Core is really at?
- Vivian: I don't know. If I knew where the real Core was, I'd destroy it without a second thought.
- Vivian: Dina, you understand what the Sacrifices are, and you know those who were "blessed" should not have to endure such horrors!
- Dina: Oh? They shouldn't have suffered those horrors?
- Dina: Weren't you the one who decided if they'd be "blessed" or not?
- Dina: If it weren't for your tears, how would they have encountered such misfortune?
- Dina: How self-righteous, Vivian. Their fates were in your hands.
- Dina: It was you who brought disaster on them.
- Vivian: Landon just needed an excuse! He needed someone to blame!
- Vivian: Whether I shed tears or not, he'd treat living beings as mere subjects for his Sacrifice experiments!
- Vivian: Dina, you know all of this! Landon even went so far as to sacrifice you—
- Dina: Shut up, shut up, shut up! Father did it for his great cause!
- Dina: Vivian, why do you always mess everything up for me? Everything!
- Dina: You did it before, and now again!
- Dina: You just had to ruin my plan! I was so, so close, to fulfilling Father's last wish!
- Dina: If you don't give me the Sacrifice Core, be prepared to become food for the Ethereals.
- Vivian: I told you, I don't have the Sacrifice Core. Otherwise I would have destroyed it already.
- Vivian: Lord Phaethon, find the right moment to retreat. She can be quite unpredictable when her temper flares.
- Dina: Oh, really? You don't have it?
- Dina: Then I suppose there isn't a reason to keep you alive.
- As Dina finishes her words, several explosions erupt, followed by tremors in the ground, signaling the rapid approach of numerous Ethereals.
In a panic, Hartman rushes to the car he summoned, taking Camille and Dina with him.
- (Enter Combat)
- Vivian: More Ethereals are coming.
- Vivian: There are too many... there's no chance to get out of this...
- Vivian: Stay... away... from Lord Phaethon!

You are...?- (ProtagonistProtagonist): (MayMay /

- Yixuan: Mayflower passed along your info, and I was curious what kind of person you are, so I came to see.
- Yixuan: At first, I thought it might be a hassle, but your energy feels really calming... Quite nice, actually.

What exactly does that mean?What exactly does that mean?) - Yixuan: Hmm... Unfortunately, this isn't the right time or place to talk.
- Yixuan: I have some investigation work to catch up on, and it seems you've got quite a lot on your hands, so let's part ways for now.
- Yixuan: I'll find a good time to visit you soon.
- Yixuan leaves after saying this, while Vivian appears lost in thought, looking distracted...
- Vivian: I'm so sorry, Lord Phaethon, I'm just not feeling very well...
- Vivian: I think I'll head back for now. I'll investigate the Sacrifice Core and reach out once I find something.
Let's leave the Hollow first.- (ProtagonistProtagonist): (You don't look so great. Let's get out of here and figure things out later.You don't look so great. Let's get out of here and figure things out later. /
