Kassandra entered the experimentation chamber to find out where the humans were taken.
Kassandra travelled to the Garden of Kymopoleia, approaching the entrance to the chamber.
- Kassandra: This looks like the perfect place to hide missing humans. Locked. But I think I know what opens this.
Kassandra took out the two disk fragments and put them together. She then placed the completed disk on a small pedestal on the left, unlocking the gate.
- Kassandra: The more complicated the key, the bigger the secret.
Kassandra entered the vault and navigated her way through to a courtyard, which she found to be heavily guarded.
- Kassandra: Someone really doesn't want any visitors.
After sneaking through, she arrived at a testing room, where she came upon replicas of the mythical creatures she encountered in Greece, including the Minotaur, the Cyclops Brontes, the Writhing Dread, and the Sphinx.
- Kassandra: What... is this?
She then turned around and found a tube containing numerous humanoid creatures.
- Kassandra: Maláka!
She then heard a voice talking to her.
- Aita: I've been waiting for you, Kassandra. Welcome to the birthplace of legends.
- Kassandra: Who said that? Show yourself!
- Aita: My name is Aita. I am a scientist. And in many ways these are my children.
- Kassandra: You created the minotaur, the cyclops, the writhing dread? They're monsters.
- Aita: Are we not all monsters? Imperfect being striving towards our ultimate potential? Is that not why you are here?
- Kassandra: I'm here because a little boy's parents are missing, and all signs point to you.
- Aita: How very human of you.
Kassandra watched in horror as the humanoid creatures were instantly liquified. She made a sound of disgust and flinched away. She briefly examined the trapped creatures, either recollecting her own experience with them or listening to Aita. First she approached Brontes' jar.
- Kassandra: Grant us the sight...
- Aita: To protect our legacy.
Kassandra moved on to the Writhing Dread's jar.
- Kassandra: She nearly turned me to stone! Even now I don't feel safe staring at her.
She continued to the Minotaur's jar.
- Kassandra: I still have nightmares from my time in the Labyrinth.
She looked at a misshapen mass left in the Hekatonchires' spawn jar.
- Kassandra: Who... or what are you?
She walked to the final jar in the gallery, this one holding a massive shard of adamant.
- Aita: A metal of extraordinary properties. Restructures the portion of the human brain responsible for emotions. We've engineered it to remove fear. Enhances your more animal instincts. Why hold a weapon, when you can become one?
Once done, she proceeded further inside, fighting a group of the humanoid creatures along the way. Eventually, she reached another room.
Kassandra found them and numerous other humans held behind a barrier.
- Damades: Please help us.
- Lyra: Dikastes! You're here.
- Kassandra: Lyra? What are you doing here?
- Lyra: They came for me in the night. I'll never be safe.
An individual approached Kassandra.
- Aita: Didn't anyone teach you it's cruel to lie?
- Kassandra: What? What's cruel is abducting and experimenting on these people.
- Aita: Without sacrifice, there can be no progress. Without experimentation, there can be no perfection.
- Kassandra: You're breaking Poseidon's law.
- Aita: I am advancing knowledge for the betterment of Atlantis. Poseidon's lack of vision keeps us in darkness. But we are close. So very close.
- Kassandra: Humans are not animals to be caged and tortured.
- Aita: We created them to serve us. That is their sole purpose.
Aita looked at Lyra, who look down.
- Kassandra: Lyra. She took her own life after what you did to her.
- Kassandra: All right, I'll play. Tell me.
- Aita: Why tell you when I could show you? Just know to enter the chamber is to forfeit their lives. You cannot have both.
Aita smiled. Kassandra threw her Spear at him. However, the spear simply phased through and dropped to the ground. Aita laughed.
- Aita: You can't kill me, Kassandra.
Aita began levitating. Kassandra walked over to her spear and stomped on it to flip it up to her waiting hand.
- Aita: I can see you're struggling. What if I told you the greatest achievement in Atlantis is behind that door? And that we owe that achievement to you?
- Kassandra: What are you talking about?
- Aita: Through there is a path to immortality. For you. For us. Embrace your legacy—forget these miserable humans. Abandon morality, and the answers to all your questions are just beyond that door.
- Rhene: Please! Save us or we'll die.
Aita angrily phased through the barrier, threatening Rhene.
- Aita: You will be reborn!
He returned to Kassandra.
- Aita: Don't you want to know why you're really here? Free the people and this door will remain closed to you forever. Pass through, however, and it will lock behind you—these rats will be mine. What will it be, Dikastes, their lives, or your destiny?
- Kassandra: I'm sorry.
- Rhene: No! Please!
- Damades: Don't leave!
Kassandra went through the door, discovering multiple clones of herself.
- Kassandra: What? No... impossible.
Aita spoke to Kassandra through voice as she looked through the clones.
- Aita: You. It was always you. Human. Isu. Perfection. The Isu blood coursing through your human body makes you the perfect vessel. It has endowed you with their resilience, and our consciousness. More so than any of my creations, you are what Project Olympos was always meant to be. The ultimate weapon. Imagine if we controlled an army of you—the inevitable war between the humans and the Isu would be over in a heartbeat.
- Kassandra: Not if I cut down every last one of these things.
- Aita: Don't waste your energy. We can always create more.
Kassandra moved towards the barrier while Aita sighed in disappointment.
- Aita: Very disappointing. No matter. if there are two things Atlantis has in ample supply, it is adamant and humans.
Kassandra removed a power source on a pedestal near the barrier, deactivating it.
- Kassandra: Come on, let's get out of here.
- Damades: Thank you, Dikastes.
- Rhene: I'll get to see Alkon again.
- Kassandra: Hurry!
The human captives escaped the chamber. As Kassandra directed the humans, Juno looked at her alongside Aita, before quickly disappearing through the door. Kassandra then followed the humans outside.
- Rhene: How can we ever repay you?
- Kassandra: Tell your son if an Isu ever calls him a rat again, Dikastes Kassandra will deal with them personally.
Rhene and Damades left.
- Kassandra: Poseidon lied to me. They've been experimenting on humans this whole time.
Kassandra discovered that human experimentations had been performed despite a law passed by Poseidon to ban experimentations.
