Chapter 1: The Last Calculation
Beep.
Beep.
Beep.
Beep.
The heart monitor counts my remaining seconds with the grim diligence of an accountant auditing a bankrupt estate. Rhythmic. Indifferent. Precise. I usually silence it — the beeping is the auditory equivalent of someone reading your eulogy aloud while you're still in the room — but today I've left it on. Today, I want to hear it.
Today, after all, is the last day it will matter.
My name — in the world that's about to end, at least — is Brainiac. And Yggdrasil, the only world worth inhabiting, is being switched off at midnight.
It's 10:03 PM. I know this not because I checked the clock but because I have, through years of involuntary practice, developed an internal chronometer accurate to within forty seconds. One of the few advantages of existing primarily in a room where the most exciting variable is whether the ceiling tile directly above the bed has acquired a new water stain. It has. Slightly larger than yesterday. I've named him Gerald.
I haven't logged in today. The hospital had opinions about this — tests, scans, the weekly ritual humiliation they call physical therapy — and the hospital, as always, won. You're probably wondering what I'm doing in a hospital. You're probably picturing something manageable. Something dramatic but surmountable, the kind of illness that serves as a third-act revelation in a prestige drama before the protagonist rallies triumphantly in the final twenty minutes.
Allow me to disabuse you of that notion.
I have Marfan syndrome. In the broadest, most generous interpretation: I am very tall, very thin, and constructed somewhat loosely, as though assembled by someone working from a diagram they'd only half-read. My limbs are long and elegant in the way that a bridge is elegant before the structural engineers discover the contractor cut corners. My lens has partially dislocated. My aorta is, according to the most recent imaging, "expressing concern." My connective tissue — the biological equivalent of load-bearing walls — is the architectural philosophy of a man who has never heard the word "collagen" used in a positive context.
I also have Angelman syndrome. Which means, among other things, that I experience seizures with the cheerful regularity of a Swiss postal schedule, have spent significant portions of my life being assessed by people with clipboards and expressions of careful neutrality, and possess a relationship with language that I have — through sheer, pigheaded, pathological force of will — largely overcome, to the considerable bafflement of every neurologist who has ever reviewed my file. My IQ, the last time anyone measured it, registered in the 99th percentile. The clinician who delivered that result looked personally affronted. I found this delightful.
The two conditions, taken individually, would each represent a significant obstacle to what medical professionals diplomatically term "quality of life" and what I more accurately term "the ability to exist without becoming a full-time administrative burden to the Swiss healthcare system." Together, they represent something considerably less negotiable.
I also have Osteonecrosis, because apparently the universe operates on a subscription model and keeps adding features I didn't request.
For the uninitiated: Osteonecrosis is what happens when your bones — already navigating the structural instabilities of Marfan syndrome — are additionally deprived of adequate blood supply, causing them to undergo a process that I describe to the curious as "rotting from the inside" and that medical literature describes in considerably more syllables. My skeleton, in short, is engaged in a slow act of self-destruction that no intervention has yet successfully interrupted. My body has been attempting to resign from its position for years. I've been overruling it on a technicality.
Until tonight.
I am twenty-six years old. I live in Switzerland, where Medical Assistance in Death is not merely legal but administered with the characteristically Swiss combination of compassion, efficiency, and documentation. I signed the paperwork this afternoon. Noemi — the nurse, the good one, the one with the careful hands and the laugh she tries to suppress when she thinks it's inappropriate — left the room holding the clipboard with an expression I have chosen not to examine too closely.
We talk, Noemi and I. Not about anything consequential. The weather, which I cannot feel. The hospital food, which I do not eat. The date she mentioned recently — Benjamin Wiederkehr, apparently, some man who exists in the world and moves through it freely and has no idea he is being held to an unofficial standard set by a dying twenty-six-year-old who has never met him and never will.
I hope he's worthy of you, Noemi. I thought it, but didn't say it, because some thoughts are more useful kept internal than spoken aloud, and because she was already walking away, and because what would be the point.
She's seen the pain I'm in. I think, on some level, she understands.
And if she doesn't — well. It won't be my problem after midnight.
Yggdrasil was the only place my body didn't follow me. The only place I wasn't was a collection of deteriorating systems in a building with a condemned notice on the door. In Yggdrasil, I was Brainiac — silver, precise, armored in the aesthetics of cold intelligence and calculated menace — and I was powerful, and I was free, and none of the cells in my body were staging a coup.
In one hour and fifty-seven minutes, the servers go dark.
So it goes. Everything remarkable ends. The only reasonable response is to be present for the ending.
I reached for my headset with careful, deliberate hands — the hands of a man who has learned the hard way that enthusiasm is structurally inadvisable — pressed the power button, and strapped it on with the practiced patience of someone for whom every physical action is a small negotiation.
The clock read 11:45 PM.
Move, I thought at the loading screen with the same tone I use for everything I cannot actually compel. I didn't come here to watch a progress bar.
Booting up... Boot successful. Loading last saved location: Nazarick — 9th Floor: Royal Suite. START
[Third-Person POV]
"Hey..."
HeroHero's voice arrived before the rest of him — low, eroded, the voice of a man who had been leaving himself in the office and collecting the remainder at the end of each week until there wasn't much remainder left. His avatar matched it with almost literary precision: a purple slime, half-dissolved across the chair and spreading lazily onto the table, a being in the advanced stages of losing its definition.
"...It's been a really long time, hasn't it, Momonga?"
Across the table, Momonga considered his friend. Seven feet of undead mage, robes immaculate, posture composed — and behind the avatar, a man watching the slow dissolution of someone he cared about with the careful stillness of a person who has learned that saying I'm worried about you too quickly just makes people apologize.
"I didn't think you'd come, HeroHero," Momonga said. "It's been... about two years, hasn't it?"
"Has it really?" A pause. The slime shifted in what might have been a wince. "That's bad. I've been doing so much overtime that time has just... stopped being a thing I track. Like a dimension I let lapse."
"Isn't that a sign worth paying attention to?"
HeroHero didn't answer that. He leaned back — or the slime distributed itself further, which amounted to the same gesture — and looked around the chamber with the slow, taking-stock expression of someone revisiting a place they'd expected to feel more nostalgic about and finding the nostalgia arriving on a delay.
"My body," he said quietly. "It's completely worn out."
The words landed without cushioning. Momonga sat with them for a moment.
HeroHero seemed to hear himself. He straightened — or consolidated, at least — and folded what passed for his arms on the table. "I'm sorry. I didn't come here to make this depressing."
"Please." Momonga's smile emote flashed, genuine. "Don't apologize for being honest."
"I should go soon. I'm falling asleep in real time." The slime avatar began drifting toward the logout menu with the inevitable gravity of a man for whom sleep had become a medical necessity rather than a preference.
"Get some rest."
"I really am sorry about this." HeroHero paused at the threshold of the menu, and for a moment neither of them moved. Then: "But I have to say — I'm genuinely surprised Nazarick is still here. You've been maintaining it this whole time, haven't you? All of it, by yourself."
"Not entirely by myself," Momonga said. "Brainiac helped."
A small, surprised sound from the slime. "Haven't seen him in ages. How is he?"
"He's well." A beat. "He logs in late, most nights. But he comes."
"Well." HeroHero's avatar shimmered faintly at the edge of logout. "Tell him I said thank you. Both of you." A pause that held more than it said. "See you IRL, Momonga."
"Definitely."
HERO HERO HAS LOGGED OFF
The chair was empty. The room was not quite — it held the specific weight of a recently vacated space, the atmospheric residue of someone who had just been present.
Momonga looked at it.
"It's the last night the servers will ever run," he said, to the empty chair, to the room, to no one. "You could have stayed until the end."
He already knew why his friend hadn't. He turned away.
"No. I'm glad he came at all." His voice dropped. 'See you IRL,' huh.
The desk received a fist.
BANG.
"You have GOT to be—"
"Mmm. Yes. Very stirring. A solid six out of ten — points deducted for the lack of a soliloquy and the fact that the desk is, demonstrably, completely uninjured."
The voice arrived with the unhurried precision of a surgical instrument laid down on a metal tray: cold, exact, and somehow already several steps ahead of where the conversation technically was.
BRAINIAC HAS LOGGED ON
In the doorway stood a figure of immaculate, terrible geometry. Silver-plated, sleek as a theorem, every line of his Magical Automaton frame composed with the deliberate aesthetic of something that had decided long ago that it was better than you and had since moved on to the more interesting question of by exactly how much. His chassis caught the light and held it — not warmly, but in the manner of a collector tagging an acquisition. At his collar and joints, pale blue light pulsed in slow, even intervals, like the heartbeat of something that had optimized breathing out of its design.
His face was featureless and mask-like save for the eyes: two cold points of luminescence that catalogued the room, assessed it, found it acceptable, and moved on to Momonga in approximately the same motion.
"Brainiac?!"
"In the flesh," Brainiac said, and the slight pause before flesh suggested he found the idiom mildly amusing in a way he was too composed to vocalize. "So to speak."
Momonga stared at him.
"...You heard all of that, didn't you?"
"The desk-striking, the yelling, the melancholy monologue in the direction of a recently vacated chair?" Brainiac tilted his head precisely four degrees — the exact angle, one might note, of polite condescension at its most efficient. "I arrived at the corridor approximately forty seconds before I entered. I made a considered choice not to interrupt the performance. Some experiences deserve to conclude organically."
"That's not—" Momonga started.
"You were, I'll grant, emotionally committed. There's something almost admirable about a being made of bones finding ways to feel them."
Momonga looked at him for a long moment.
Then, despite every reasonable intention, he felt his face — his real face, behind the headset — pull into a smile.
"You're insufferable," he said. "I missed you terribly."
"Of course you did," Brainiac said, walking into the room with the measured pace of a man in no hurry because hurry implies the destination might escape him. "I elevate the average intelligence of any room I enter by a statistically significant margin. Your subconscious recognized the deficit."
"And you call me dramatic."
"I am not dramatic." He stopped at the center of the room. "I am precise. There is a distinction, and it is not a subtle one."
Momonga stood and crossed to the bejeweled staff resting at the room's center. He gestured to it. "Do you remember what this is?"
Brainiac regarded it the way a chess grandmaster regards a board someone else left mid-game — assessing, categorizing, and extracting.
"The Staff of Ainz Ooal Gown." A pause. "The name remains an act of linguistic violence that I have never fully forgiven." His gaze tracked up from the staff to Momonga. "I remember when Wish III nearly filed for divorce over the materials acquisition. His wife had opinions about the time investment. Loud ones. Audible through three different voice channels simultaneously."
Momonga laughed — a genuine one, the kind that bypasses the parts of you that are busy grieving. "Those were good days."
"They were adequately stimulating," Brainiac allowed, which, from him, was essentially poetry. A brief quiet settled between them — not uncomfortable, but weighted. "The throne room."
"Is your Swiss showing?"
"I have no idea what that means."
"I'm being told it's the Swiss version of 'eh.'"
A pause so precisely timed it could have been metered. "I was born in Geneva, raised on three continents, and educated by systems that would individually represent the intellectual peak of most nations. I do not have a 'showing.'" He turned toward the corridor. "I was making a suggestion. There is a distinction—"
"And it is not a subtle one, yes, I know." Momonga was already walking, grinning. "You've mentioned."
"I mention it because it bears repeating."
They moved into the hallways of Nazarick — the grand, impractical, magnificent hallways that forty-two people had collectively imagined into existence and one man had quietly maintained, and one other had kept him company through the maintaining.
"Your L's are improving," Brainiac said, without preamble, into the silence.
Momonga blinked. "...Thank you?"
"Do not read sentiment into the observation. I am simply noting a measurable improvement in phonemic accuracy. It would be statistically dishonest not to acknowledge it."
"That," Momonga said, "is the most Brainiac compliment I have ever received."
"All my compliments are the most Brainiac compliment you've ever received. That's definitely true."
Their laughter — one rich, one dry — rolled through the corridor and dissolved into the architecture, the last sound of two people who were very good at finding each other funny and had never quite said so directly.
Rounding a corner, they encountered Sebas and the six Pleiades battle maids, standing in the practiced stillness of NPCs awaiting instruction. At the approach of two players — perhaps the last two players — they bowed in perfect, silent unison.
Brainiac observed this for a moment.
"Shall we walk them to the throne room," he said, "or is it more dignified to let the guard stand an eternal watch over a hall no one will ever breach?"
"It's the last night," Momonga said. "Let's give them a walk. What's the command again?"
An exceedingly brief pause, of the variety that communicates I cannot believe I am being asked this. "Follow."
"Right." Momonga cleared his throat. "Follow."
Sebas straightened. The Pleiades fell into formation. The procession continued — Momonga contemplative, Brainiac performing what could generously be called walking, but what was more accurately a form of locomotion that suggested he was simultaneously cataloguing every structural detail of the corridor and finding most of them adequate.
"Didn't we assign them to guard the throne room?" Brainiac asked, at length.
"We did. But no player ever made it this far."
A pause that contained an entire editorial. "Unfortunate for them," Brainiac said. "For us, vindicating."
The throne room doors were cathedral-tall and cathedral-heavy, and they opened onto something that had no right to be as moving as it was: the great vaulted chamber, the banners of forty-two absent members hanging from the ceiling like the flags of countries that no longer existed, and at the far end, framed by shadow and architecture, the throne.
Momonga stopped just inside.
"Isn't today your birthday, Brainiac?"
A silence of unusual quality.
"It is." Brainiac did not turn. "Why do you ask?"
"Just thinking about something." Momonga looked up at the banners. "Happy birthday."
Another silence. This one was different — shorter, denser, the kind that forms when something lands, and the recipient needs a moment to determine what it is.
"...Thank you," Brainiac said. The words were measured as always, but the measure was doing more work than usual.
They continued into the chamber. The maids stationed themselves along the walls, waiting. At the foot of the throne stood Albedo — the succubus, wing-folded, wearing the small, static serenity of an NPC who would outlast the players only by a matter of minutes.
Momonga moved toward the throne. He stopped at the steps.
Brainiac was already in front of Albedo, studying her with the particular quality of attention he reserved for things that interested him despite all practical reasons not to be interested. His head was tilted, not at the polite four degrees but at something wider — something that, if you were watching carefully, looked almost like loss preemptively wearing the clothes of analysis.
"You've always liked her," Momonga said.
"I have always found her composition remarkably well-executed," Brainiac said, with the tone of a man reading from a carefully prepared statement and finding the statement slightly less believable than when he'd written it. "The architectural design. The behavioral logic framework. The aesthetic coherence. Tabula-san built a character of genuine structural sophistication."
"That's not what I said."
A pause. "No," Brainiac said. "It isn't."
He looked at her — truly looked, in the way that bypassed the analysis and arrived somewhere underneath it.
"There is a particular kind of beauty," he said at last, "in a thing that cannot change. Cannot age, cannot diminish, cannot be disappointed by the passage of time or the failures of the world. She is exactly what she is, and she will be exactly what she is until midnight, and then she will simply—" He stopped.
His head turned slightly toward Momonga, the pale light at his collar pulsing once, slow.
"I simply wanted to enjoy Nazarick while it lasts," he finished. "Our guardian leader included."
Momonga was quiet for a long moment. He looked at Brainiac — truly looked, the way you look at someone you've known for six years and are suddenly, quietly aware you are looking at for the last time.
"I've been thinking," he said, "about a birthday present."
Brainiac turned from Albedo. "A birthday present." The faintest, driest note of something that in a less composed man would have been disbelief. "I hope it isn't consumable. I don't eat."
"What if I made you Guild Leader?"
The throne room held the silence on their behalf for a moment.
Brainiac's luminescent eyes did not change — mechanically, expressively, they were incapable of it — but the stillness that passed through his frame was the kind that doesn't come from composure. It comes from being, very briefly, caught entirely off-guard by something that matters.
"...Guild Leader," he repeated. The words were barely voiced. He stood with them for a moment, the way one stands with a diagnosis — processing, reclassifying, recalibrating all the surrounding data. "That is," he said at last, with the careful enunciation of someone determining if the emotion they're experiencing is appropriate to the occasion and deciding, for once, not to adjudicate, "a remarkable gift."
A pause.
"I accept." Quieter still. "If you'd have me."
"I'd have you."
Momonga opened the guild panel. The transfer took four seconds. He stepped back, extended the Staff of Ainz Ooal Gown, and presented it without ceremony, because some moments don't need staging.
"It's done. You are the Guild Leader of the Great Tomb of Nazarick."
Brainiac held the staff.
In the real world — in the hospital room in Geneva, where the heart monitor had continued its faithful accounting of a life approaching its final entry — the man behind the silver chassis sat very still and felt something move through him that had no name in any of the three languages he thought in fluently.
He had never been given anything, not really, not in the way this was a gift. Not something that said you mattered here, you were part of this, this was yours. The game was ending in four minutes. He would be gone in four minutes. And they had given him the best seat in the house for the final act, and the house was burning down, and somehow it was perfect.
"Thank you," he said. The words were simple, stripped of their usual architecture. "Truly."
"I'm glad." Momonga moved toward the edge of the chamber, toward the quiet dignity of an exit well-timed. "I'm going to log off. The throne is yours, Guild Leader."
"What is a throne," Brainiac said, "without subjects to witness it?"
"I haven't the faintest idea." Momonga turned once. The smile in his voice was unmistakable. "Ask me again when you've had one for more than three minutes."
"...Goodbye, Mugs."
"See you."
MOMONGA HAS LOGGED OFF
Brainiac stood alone in the throne room.
The banners hung overhead like the memory of forty-two arguments, forty-two enthusiasms, forty-two people who had built something magnificent and then gradually drifted back to the world that asked more of them than a dungeon did. The battle maids stood at their stations with the faithful stillness of things that had never needed to be anywhere else. The room was quiet in the way that only very large, very old spaces know how to be quiet.
He crossed to the throne. Slowly, for once, not the measured pace of calculated precision, but the slow step of a man who has nowhere urgent to be and has decided, finally, to let that be enough. He stood before it. He looked it over. He thought: We earned this, and then we included people who would never know he was sitting here.
Let's hope it's comfortable.
He lowered himself into it. Set the staff to float beside the armrest. Took in the view.
It was, he decided, a very good view.
After a long, quiet moment, he looked to Albedo, standing at his right, turned toward him, waiting.
"I should give my first order as Guild Leader," he said. "It would be statistically negligent not to." He considered. "Kneel."
The battle maids dropped as one. Sebas bowed, precise and sincere. Albedo folded to one knee with the grace of something purpose-built for it, her head lowered, that small perpetual smile unchanged.
Brainiac looked at her.
Then, with the air of a man doing something he has already argued himself out of twice and is now doing anyway, he reached over and opened her character script.
He read it. His expression — which was, architecturally, incapable of changing — somehow conveyed in its absolute stillness the specific quality of a man reading something that confirms a long-held suspicion about a friend.
"A bitch," he said. The word was entirely neutral, in the way that extremely precise language sometimes achieves a neutrality that is itself a form of comment. "Tabula-san. Of course."
He selected the descriptor. His finger hovered.
He deleted it.
The field sat blank.
He stared at it. He stared at her. He thought, with the methodical rigor he applied to everything including things he would rather not be methodical about, about the particular cruelty of a world in which one could write she loves him into a script and watch the script do absolutely nothing, because the script was not the same as the thing, and the thing had never existed, and in four minutes, even the script would be gone.
The cursor blinked. Patient. Morally indifferent.
"Ha," he said, very quietly, to no one. "What the hell?"
He typed.
She is madly in love with [Brainiac].
He read it back. He experienced, in rapid succession: amusement, the specific kind of warmth that has nowhere to put itself, and a grief so clean and precise it was almost elegant. He had, he reflected, spent considerable intellectual energy throughout his life arriving at feelings and immediately beginning to classify them, as though naming the specimen somehow placed it safely behind glass.
It did not, as it turned out, place it safely behind glass.
"Appropriately ironic," he said aloud, to the empty throne room, to the motionless guardian who would not move or speak or look at him differently because of four words he'd typed where no one would ever read them. "The most powerful man in Nazarick, for the next—" he checked the countdown — "three minutes and forty-one seconds, has written himself a love story that the universe has declined to render."
He was aware that he was speaking to an NPC. He continued anyway. The heart monitor, back in the real world, maintained its faithful rhythm.
Beep.
Beep.
Then: a small, distant sensation in his arm. A pinch — gentle, professional, Swiss in its precision.
"Ah," he said. "There it is."
The countdown appeared at the edge of his vision.
00:00:07
00:00:06
00:00:05
00:00:04
00:00:03
He looked at Albedo. He looked at the throne room. He looked at the banners of forty-two people who had, in their way, given him a world to live in when the one he'd been issued proved structurally unsuitable.
"It was fun," he said, quietly, with the absolute sincerity of a man who has spent his whole life being precise and finds, at the end, that precision is only useful when you have something true to say with it. "It was genuinely, remarkably fun."
Goodbye, Noemi. I hope Benjamin Wiederkehr is everything the clipboard didn't deserve.
Goodbye, Mugs. You kept the lights on.
Goodbye, all of you.
I'll see you in the next calculation.
00:00:01
00:00:00
He closed his eyes.
00:00:01
00:00:02
00:00:03
He opened them.
"WHAT?"
