"May I dissect your brain?"

This Promestein comes from a timeline where Ilias was able to defeat and annihilate Alice the 1st, including the Six Ancestors, thanks to the Seven Archangels, whereas in the original trilogy, Ilias had forced Alice to seal herself and the Six Ancestors, or Ilias would destroy the world.

Biography

Rostrum Tartarus

Promestein is first encountered in the second Tartarus.

While exploring the Tartarus, the group arrives at the doorway to the next dimension. Since Luka has the power to travel between dimensions, he need only touch it for the door to open. Something a mere human shouldn't be capable of doing in the first place. Heading through the door, the party is back in Remina. A figure wearing glasses, with red hair peeks out of the house on the other end of the street before rushing back in again.

They investigate the home, where they find a younger Promestein. Luka inquires what Promestein is doing here, but she asks what year it is instead. Luka tells her that it's Johannes 1455 where they come from, and Promestein notes that she must be quite some time behind them. She explains that she unintentionally teleported herself into this dimension while testing the reactions between holy and dark magic. She's been stuck in this dimension ever since. Luka promptly asks if she caused the Great Disaster, but Promestein tells him that her small experiment shouldn't have been able to cause something of that magnitude.

Ever since she arrived, she's been studying Remina and conducting more tests, making equipment out of the resources available to her. Sonya mentions that she must have been here for a long time. Promestein replies she's been here almost 200 years.

She asks how Luka managed to replicate her experiment, and if he can provide details on it to help her research. Ilias explains that there was no such experiment. Luka has the power to travel between dimensions. Promestein says that it shouldn't be possible for a human to do that and asks Luka if she can dissect his frontal lobe to find out why. Luka declines for some reason. She suggests making a clone out of him as an alternative, so she asks Luka to ejaculate into a beaker, which he also declines to.

You can recruit Promestein here. She reassures Luka that there shouldn't be any noticeable side effects from losing a piece of his frontal lobe. She joins the party as an excuse to investigate Luka further. Promestein still hasn't figured out who Ilias is, either.

Looking through Promestein's notes reveals some of the numerous breakthroughs she had while studying apoptosis. She learned that it is a phenomenon that occurs wherever chaos is. It transforms the inhabitants of that dimension into apoptosis beings, meant to repel foreign invaders by erasing them. However, some of the apoptosis beings retain their memories.

Rostrum(Alt)

After Luka and the others exited the Chaos Passage, Promestein asked a local guide what year it is, and realize they got sent back 25 years when Marcellus was still adventuring. Promestein wants to take some samples for her experiments before leaving. She is excited to return back to Luka's world and to travel to other worlds.

Enrika Forest

Arriving at the Enrika Forest filled with Elves and Fairies, Promestein wants to dissect Dark Elves with a smile on her face. 

Iliasport

On Ilias route during the camp, Promestein informs Ilias about the new angels in the seraph classes known as Gnosis and Zion, as Ilias never knew about the two new angels. Ilias thinks that Micaela and Lucifina are still in the ranks. Promestein reveals that Micaela became the leader of the 7 archangels and Lucifina has "retired" from her duty to the Goddess Ilias, Ilias claims that they're not from this world and so does Promestein.

Arriving at Iliaspor,t Promestein wants to head for the university and heads in, where she shows her intelligence to a scholar and leaves in anger as she thinks the man is backward. Promestein prepares to make some research on the cave of treasures.

Cave of Treasures

Promestein learns more about the White Rabbit's motive is to try and correct the history after Luka is defeated by Nanabi.

Port Natalia

Promestein couldn't believe that Zion came to Luka's world to fight Morrigan, and speculates that Zion is from this world, which is denied by Luka and Ilias.


In a sidequest, Promestein introduces herself to Bunni, who can be found in Port Natalia eating carrots as she thinks it will make her a rabbit, even if Sonya says that's not true at all. Promestein injects Bunni to change her race of Bunni from Slime to Beast. Promestein is pleased with her experiment and just informs them that they can change their former race back at Ilias Temple. It then becomes possible to change the race of slimes to beasts in the Pocket Castle.

Southern Undersea Temple

Luka and the others arrives at the Southern Undersea Temple. They spot the mermaids who tell the group that they were imprisoned by Meia . Promestein explains that Meia is seem to be struggling against her brainwashed state. After Luka defeats Meia, Promestein says that her eyes now return to normal.

San Ilia

When the party arrive in San Ilia, they directly to the castle to speak with the Pope. Along the way Promestein hears a man preaching about the destruction of this city that will be judged by Ilias. While the small goddess doesn't approve of using Makina, she wouldn't destroy a city who worships her, even if Promesteins says otherwise. After Luka receives instruction from Marcellus his father from a note in the library, Promestein still wants to know more about the true history and the chaos in this world.

Mt. Saint Amos

Arriving at Mt Saint Amos, she and Ilias sense a powerful angel on top of the mountain. When they go to investigate, they see Micaela being critically injured, and the fallen seraph warns the party of Gnosis, one of the Seraph from the Angel World along with Zion. Ilias doesn't recognise the angel but Promestein knows her well and wonders why she would attack Micaela. Micaela then fades into particles of light and vanishes. Promestein wonders why Gnosis would arrive here.

Luddite Village

Promestein shows herself to be extremely critical of the villager's lifestyle, calling it a step backward in evolution.

Ancient Temple Ruins

Arriving at the Ancient Temple Ruins, the party is surprise by the modern technology in the ruins, especially Promestein.

The technology within the temple is at least a hundred years ahead of the technology of the paradox world, much to the fascination of Promestein.

Within the temple, they come across a terminal. The group discovers that when this research facility was abandoned, the previous owners erased all of their previous records, explaining why Hild possesses such little intelligence. They likely deleted most of her memory before leaving the lab. The only thing she remembers is that her master was the most important person in the laboratory.

Ilias asks Hild whether or not there is a possibility of Promestein being her master. One from another dimension. Hild confirms this is incorrect, as her master was completely different compared to the description Ilias provided of Promestein. The fact it wasn't Promestein disturbs Ilias, as one of the creatures, XX-7 is one of Promestein's creations. But that's not to say Promestein didn't work with the scientists.

At the second terminal, they find information on apoptosis, confirming the scientists working there are aware of chaosization. Like the previous terminal, research information has been erased. The only information remaining is regarding Hild. It confirms that Hild was created to battle with apoptosis. She has a holy and dark fusion core, as well as the body tissue of apoptosis beings built into her. Hild confirms that she remembers her master telling her that she would awaken when the world ends. They kept her in the pod in a hibernation mode until that happened. 

Despite her numerous combat functions, Promestein believes that Hild was not built exclusively for warfare; otherwise, she wouldn't possess an advanced reproduction system or such advanced emotional processors. Also, she shouldn't be so stupid to the point she answers 87+65 as 142.

At the third terminal, they discover the exact date, time and coordinates of where Promestein was sent to the eastern Tartarus. The same day she supposedly did the experiment. The fact the lab administrators had access to this information confirms that it wasn't Promestein's experiment which sent her back in time, but this device. While it was her experiment which created the crack in spacetime, it was the lab administrators who set the coordinates to Tartarus. If it hadn't had been for the device, she never would have been pulled through the rift. But combining divine and dark energy is the key to creating these cracks in spacetime.

Ilias is confused why they would want to send her through one, but she has no idea. If they had just wanted her dead, throwing her into another world would have been a waste of resources. She hypothesizes that they perhaps sent her through to join Luka when he passed through there. At a particular time on his adventure.

At the final terminal is Hild's capsule. Within the capsule's data, Promestein finds that Luka's biometric data had already been integrated into it, explaining why Hild woke up when Luka touched it. But only Luka's data was integrated to wake her up, no one else. Ilias inquires whether Luka is familiar with the ruins at all, but he replies he's never heard of it in his life.

Promestein brings up that Ilias has been referring to the laboratory as ruins for a while now, but that is incorrect as this scale of technology never existed in those times. However, compared to the technology in the Tartarus which appeared out of nowhere, they are very similar. Promestein believes that this laboratory came from a parallel world, and asks Hild what the date is according to her data. She responds that it should be 1543, but has configured it to 1455 since waking up, meaning that Hild is 88 years ahead of them.

Haunted Manor

Promestein was reluctant on defeating Chrome and Fredrica since she does research on science and magic similar to hers but agrees anyway. 

Forest of Spirits

In Part 2's ending, Promestein hear rumors about the alternate reality version of herself making chimera beasts for Goddess Ilias. In the meantime, Ilias remembered that the Promestein from the true history had put the Six Ancestors Great Seal on herself and onto Alice before White Rabbit can re-seal her so that the timeline can be followed as it should.

In Ilias's route, she decides to return to the temple's ruins accompanied by Luka to check if she can learn anything more about the place. The party encounters Morrigan who gives them a few details about the Lilith Sister's plan to save the world. Soon after, Alma Elma arrives to take Morrigan down, but the blue haired succubus flees. The succubus queen then gets challenged by the party and joins them after being defeated.

On Alice's Route, the expedition is identical but Morrigan is the one initiating it.

In upcoming events she and Chrome received a mysterious message from the organization called "Alliance of Wisdom" and fails to answer the questions she's asked. She wonders what it's about, but decides to turn her research toward answering them.

World Interactions

Pocket Castle

Basic Greeting:

"Could I come along and observe? And, in the event of your defeat, may I dissect you as well?"

With Chrome:

Chrome: "I am Chrome, the researcher of zombies!"

Promestein: "I see... That is a surprisingly respectable field. I was expecting it to be mostly quackery."

Chrome: "That's rude... I was originally taught by my older sister, and now the techniques of the Artiste family have been passed down to me."

Promestein: "Oh, the left and right arms of this zombie have been switched... You seem to be lacking in the fundamentals."

With Cornelia:

Cornelia: "My, miss scientist. I'm surprised that you almost never come to the library."

Promestein: "Books are an inefficient path to gathering information. Reading is too time-consuming. It's a huge waste of time."

Cornelia: "Isn't it fine for them to be a waste of time? Not everyone reads for the sake of gathering information."

Cornelia: "They do it for entertainment. It's fun to pass the time reading. I think reading is a nice distraction."

Promestein: "Is it a bit like eating to your heart's content without paying attention to calories?"

Cornelia: "Well, something like that... Do you not care for dieting?"

Promestein: "I prefer everything to be closely managed."

With Hild:

Promestein: "Geez... Who you are, what your purpose is, and even your power supply are all unknown..."

Hild: "Hild is a mystery... Am I from Wonderland?"

Promestein: "I can take care of your piece of junk brain circuits. Mind if I dismantle you for a bit?"

Sonya: "The answer is no!"

With Jaide:

Jaide: "...What?"

Promestein: "You have a surprising number of organic components. In fact, most of your components are organic."

Jaide: "I am not a robot. I am a mechanical lifeform."

Promestein: "You seem to have undergone a fairly unique evolution. Is it all right if I dismantle your leg for a bit?"

Jaide: "No good would come of it..."

With Lucia:

Promestein: "You're studying alchemy, right?"

Lucia: "More than the mysteries of alchemy, my goal is to uncover the truth of all things. This is just a step on the long road to that truth."

Promestein: "I see... So you also seek the ultimate truth. Only those who overcome all obstacles to seek the answer to everything are my allies."

Promestein: "As such, I hope we can get along in the future. It's a pleasure to meet you."

Lucia: "Yeah, same here."

Ilias: "(Brrrr, that gives me chills...)"

With Luxuru:

Promestein: "Now this is an unusual machine... Its nerve center resembles that of an organic lifeforms."

Luksl: "What are you saying? I was originally human. I was fused to this machine, but my upper half was never processed."

Promestein: "But most of your brain has been altered... It can hardly even be called organic."

Luksl: "...Huuuh? Hey, is that true?!"

Promestein: "Aren't you excited?!"

Luksl: "No!"

With Nuruko:

Nuruko: "Kyukyuu, Kyuu. ♪"

Promestein: "What an unusual organism... Just what is it?"

Nuruko: "Kyu...?"

Promestein: "Don't worry, it won't hurt. It'll only tingle a bit."

Sonya: "Hey! Stop picking on Nuruko!"

Promestein: "No, I was only taking a small sample... Sorry."

With Radio:

Radio: "Master... It haSBeen 14 years, 3 months, 18 days, 14 hours, 35 minutes, and 48 seconds."

Promestein: "Huh? ...I don't know what you're talking about."

Radio: "I don't knoWEither."

Promestein: "R-really...?"

Radio: "But I feeLLike... I have a stronGSense of nostalgia."

Promestein: "That's pretty vague for a machine... Was your creator this vague?"

With Sylph:

Promestein: "The spirit of the wind. Fascinating... Is it alright if I put you in a jar and run some experiments?"

Sylph: "No waaayyyy!"

Promestein: "Then may I have a sample of your internal organs? I'll even replace them with cotton."

Sylph: "Okay!"

Sonya: "No it's not!"

With Valto:

Promestein: "This part appears to be designed for battle as well."

Each section is able to expand into a capture device."

Valto: "Do not touch without permission... It's dangerous..."

Promestein: "I see, it expands from here... Ahhh! It closed! I'm stuck!"

Valto: "Since you are trapped, reflect on your actions for a while..."

Ilias: "You should release her immediately. Confining her only make her worse."

Sonya: "She's already begun to take you apart... Why not just release her?"

With Ilias:

Promestein: "What's wrong? You're staring at me."

Ilias: (This time I will have you re-educated. Locked away somewhere, you will be forced to listen to my teachings.)

Promestein: "Hmm, can I have one of your feathers? I want to perform a small chemical experiment using the holy element."

Ilias: "And then you'll become my loyal pawn. Fufufu ....." (Use your own.)

Promestein: "...Huh?"

Ilias: "How rude. Now my words and thoughts are mixed up. You shouldn't speak while I'm in the middle of thinking."

Camp

Promestein: It brings a smile to my face to see everyone camped out together in high spirits. I'd absolutely love to make some dopamine and adrenaline level readings. Do you mind if i stick electrodes in a few of our companions heads?

Promestein: A scorpion is beneath this rock... Let's capture it as a sample, fufufu.

Promestein: I wonder what became of the angels in this world. Were most of them caught up in the annihilation of Heaven and destroyed? 

Luka: You have a smile on your face.

Promestein: According to Ilias, the Seven Archangels don't exist in this world . That makes me wonder if they exist in the original history. If not, then the world I'm from would also be a parallel world that deviated from the original history... Yes that would seem to be the case.

Promestein: There's so much I don't understand in the notes that La Croix entrusted to us. She wrote down formulas for things like the process of chaos spreading, but I can't understand them. How can time be imaginary or mass be negative?

Ilias: It requires a grand unified theory of relativity, quantum mechanics, and magic particles. That's beyond my capacity in this shrunken state.

Promestein: I'm taking samples of the trees here since their growth seemed rather abnormal. Though these samples were gathered at various locations, a common growth abnormality is identifiable. It's spreading from the Tartarus Rifts to the surrounding areas.

Trivia


  • When she learns how to change the race of some party members, she creates a permanent duplicate in the entrance of the Pocket Castle, which will exclusively take requests for changing one's race. She is the only party member to do this (as the other merchants will simply create duplicates when they are in Luka's party).
