[Senior Researcher Grazina Myklukho's Experimental Report: Research on Targeted Plant Breeding Based on Phenotypic Variation]

...As documented in Professor H. Verkhratskyi's experimental records prior to the apocalypse, kuuvahki exerts a catalytic effect on the growth of certain plants, inducing developmental mutations that result in phenotypes more attuned to kuuvahki...

...It is conceivable that, through artificial regulation of the mutation process, novel plant varieties with a high affinity for kuuvahki could be developed selectively... Analogous to photosynthesis... these plants would autonomously accumulate kuuvahki from their environment, thereby eliminating potential Abyssal corruption...

...Preliminary experiments indicate that most phenotypic traits of the controlled variants are heritable...

...A request was submitted to Supervisor Morozov to modify the existing ventilation system by adding pipelines for kuuvahki delivery. Circulation will be maintained by these newly bred plants (currently unnamed)...

...Although Supervisor Morozov appeared to hold out little hope that we might return to the post-apocalyptic world outside (which is entirely understandable), he nevertheless approved the modification plan...

...Now, just by opening the valves, we will have a continuous supply of kuuvahki that can be recycled...

...The people, especially the children who followed us here, should not remain in the bunker forever. One day, they or their children will discover a new world that has not yet been destroyed. By then, these flowers will help them purify the pitch-black corruption, allowing them to walk proudly under the azure sky...

Bloodstained Logs

I've been tricked. I've been tricked. I've been tricked. There's no treasure. There was never any damn treasure in this cursed place. That signal was deliberately set as bait. I should have known. The terminal was placed in such an obvious spot. If there really was treasure here, we would've heard all about this place in Nasha Town. But no one has ever mentioned it.

I mean, no one who's been here has lived to tell about it.

The door is sealed, and the elevator has left. I guess only activating this (some unrecognizable vulgar word) purification system from the outside can reopen the door. There's no way out. No way out ever again. I'm going to die here. I don't want to die here. I shouldn't have joined the Seahook Gang. I should have taken the work from those overfed and self-indulgent Fontainians instead. I'll (...) anyone, I don't care how many it takes. I don't care who I (...). As long as I don't die here. I don't want to die here.

...

There's water. These plants seem edible. I'm going to survive. I have to survive. Sooner or later, some unlucky bastard will be lured here by that signal again. When he opens the door, I'll grab my knife and (...) him, take his belongings, and escape this place. I will survive. I won't starve to death here. I won't die. Haha. I won't die.

...

Something's not right.

Come to think of it, since I came in, I haven't seen a single (...).

No, this isn't right. I couldn't possibly be the first person to wander into this place. If that signal has been broadcasting all this time, then plenty of people must have come in already. There are plenty of marks carved by Treasure Hoarders in the corners of the walls, too, though I can't make any sense of what they mean.

Could it be that there's still...

Messily-Written Notes

...This is a secret mission that only me and Big Sis Grazina know about!

...Once these flowers grow up, Little Pay will come back to play with us!

...Grazina said she's just sick and needs to rest for a while. When the flowers grow taller than my knees, she'll recover, so we mustn't cry. We need to listen to Uncle Morozov and be very good children.

...There's no sun here, but the lights up there are just as warm and cozy. As long as we water them with that shimmering water every day, these flowers will surely grow quickly!

...Grow faster, please. I miss her.

Mr. Kotelnikov went to service the purification system in Experimental Site No. 1, but contact was lost shortly thereafter. What happened?

Sincerely,

Communications Log #2

To: Supervisor R.M. Morozov

I hereby submit the final evaluation on the purifying effects of the new plant variety (hereinafter referred to as the "Experimental Plant") on Abyssal corruption. Please consider this letter my most formal request.

After months of controlled experiments, we have confirmed that the Experimental Plants demonstrate exceptional efficacy in processing high concentrations of Abyss corruption and (...) waste materials. In Experimental Site No. 2, the specimen successfully blocked all Abyssal corruption originating from outside the bunker within a short time frame, reflecting it in a pure (...) form, thereby efficiently eliminating the monsters that had previously been extremely difficult to deal with. There is no doubt that this is an unprecedented breakthrough. I am deeply grateful for the opportunity you have given us. This success is as much yours as it is ours.

However, I must also report the significant latent risks associated with such experiments. As I have repeatedly emphasized before, potential scenarios in which apocalyptic contamination could be released, and incidents of personnel casualties resulting from the escape of Abyssal monsters are all beyond the scope of our ability for subjective control. Among the most recent victims was even a child under (...) years old.

I am fully aware that Payva's death from illness was in no way a tragedy you wished to witness, and that you exerted every effort to save that child. However, as long as experiments of this nature continue to advance, the risk of contamination leakage will only grow more severe. Our responsibility is to erect a barrier that shields humanity from catastrophe; under no circumstances should we seek to test the limits of that darkness. Forgive my bluntness, but the continuation of these experiments has become entirely meaningless — unless your intention (if I may speak frankly) is simply to permit even more otherworldly entities to pour into our bunker.

Based on the aforementioned reasons, and on behalf of the research team, I hereby submit the following request:

Immediately cease all further testing of the purification system.
Thoroughly eliminate all Abyssal live experimental specimens in our custody. Ensure that no monster collection activities are conducted in any form.

Please approve as soon as possible.

Sincerely,

Terminal Log

[Private Journal of Senior Researcher Grazina Myklukho]

Morozov is dead.

So many innocent people died by his hands... So many innocent people died because of my foolishness, all for a lie that he didn't even believe himself.

I don't know who Rotwang is, and I don't know what kind of wretched plans they had. Nor do I want to know. All I know is that their blood is on my hands as well — simply because I believed their lies, because I trusted that they could truly offer a final refuge for good people.

Why didn't I realize it? When the pipelines were first added, I should have seen that they could just as easily be used to carry the Abyss's corruption, allowing Morozov to fabricate the illusion that The Outside World had long since been utterly destroyed by the Abyss.

But I didn't think of that.

Countless people, countless people who believed in me... No matter what Brahe Reed Miller says...

They all died because of me.

Brahe Reed Miller said that the Abyssal corruption here cannot be eliminated overnight, and Morozov, like Rotwang, would one day be resurrected as a mindless monster despite having lost all sanity and humanity, until the hero prophesied by the Frostmoon Scions' Moonchanter (What is this? Don't those strange people only have an archpriestess?) destroys it completely. Until then, it will forever wander these Abyss-corroded ruins, devouring the flesh and blood of those who stray in here.

I can't turn off the bunker broadcast signal he left behind, nor can I close the bunker gates that he left permanently open. Directly destroying this place would cause the Abyss corruption to spread, so I can only pray that no one will ever set foot here again.

So, I declined his offer to take me away, choosing instead to stay behind. Both to prevent Morozov's resurrection and keep innocent people from entering this place.

I can't face those surviving children anymore. What should I say if Lily asks me again when Payva's illness will be cured?

Those who repeat lies... deserve to be buried in the apocalypse alongside those who weave them.

Brahe Reed Miller seemed deeply interested in the plants that could cleanse the Abyssal Calamity, so I asked him to help me take the specimens out. When he asked why I hadn’t named them, I thought about it and realized I didn’t know myself. Perhaps I simply couldn’t bring myself to confront the truth of our experiments. In response, he said that he, a master thief, would steal the naming rights. In the end, he called them Mandragora. A fictional plant in the legends from the Far North that Miss Alia had once told him about, so he claims. In the language of flowers, Mandragoras symbolize happiness and hope.

He can have his way. I no longer have the right to protest this bitter irony.

Lore

During the reign of the Belyi Tsar and in anticipation of the Cataclysm, this bunker was built to survive the supposed “apocalypse,” in which the Abyss was believed to ravage all of Teyvat. After the Cataclysm, a team of researchers and their families lived in the bunker under the supervision of R. M. Morozov.

The inhabitants of the bunker included:

• Supervisor R.M. Morozov
• Senior Researcher Grazina Myklukho
• Maintenance Worker Kotelnikov
• Payva (Child)
• Lily (Child)

Throughout their time in the bunker, Morozov instructed the researchers to experiment with kuuvahki and its influence on the Abyss. Grazina Myklukho led experiments based on earlier research showing that kuuvahki had a catalytic effect on the growth of certain plants. Through controlled breeding, the researchers developed new plant varieties with a high affinity for kuuvahki, capable of passively absorbing it and purifying Abyssal corruption. These plants were tested on Abyssal creatures such as Rifthounds, with the hope of one day restoring the surface world.

Following the successful research, Morozov requested a modification to the ventilation system, adding pipelines to circulate kuuvahki, which was supplied by the plants. This created the "Apocalypse Purification System."

However, Morozov had actually been working for Rotwang the entire time. His goal was to use the system to secretly introduce Abyssal corruption into the experimental zones. He spread the lie that the outside world had been completely destroyed to ensure that the inhabitants of the bunker would never attempt to leave.

The experiments resulted in repeated containment breaches, numerous deaths, and even the loss of children, including Payva. Despite Grazina’s growing objections and formal requests to terminate the experiments, Morozov continued them, claiming that they were for the greater good.

Eventually, Kotelnikov discovered Morozov’s true intentions and informed Grazina that the outside world still existed, urging her to escape with the children. With the help of Brahe, the third Reed Miller, Grazina secretly arranged for the surviving children to be escorted out of the facility. Morozov remained unaware of this, and eventually died, though the circumstances surrounding his death remain unknown. Before parting ways, Grazina entrusted Brahe with the purified plant specimens, which he names Mandragoras as symbols of hope and happiness.

In her final journal entry, Grazina takes responsibility for believing Morozov’s lies and for the deaths caused by the experiments. Unable to shut down the broadcast signal or destroy the bunker without spreading corruption, she chose to stay behind to prevent Morozov’s resurrection as an Abyssal monster and stop others from entering.

During the World Quest Return to Sender in Series East of the Moon, West of the Sun, the Traveler and Paimon discover the bunker, restore the Apocalypse Purification System, and ultimately defeat the resurrected Abyssal monster that was once Morozov. They learn that Morozov himself believed Rotwang had succeeded in destroying the outside world.
