[Post that explains our syscourse stances pretty well]
We're looking for plurality resources in languages other than English or from countries outside the Anglosphere to add to our guide (last updated: 6 June 2026 in our timezone). If you know any, or are willing to help translate the guide, please tell us through asks.
Introduction
Hey there! We're Fermi — a system whose headcount fluctuates and whose headmates tend to have a lot in common. We also run @cyclogenic-culture-is. We're mostly traumagenic and relate to OSDD-1a or P-DID systems, but we're no longer sure if a psychiatric diagnosis — and all that entails — would be helpful for us. What we are officially diagnosed with is autism (level 2 support needs) and ADHD. Basically, it's like we have "dissociative identity" with less of the "disorder."
Bodily, we're an older teenager — still under 18, i.e. underage in most countries including where we live.
We are endo-friendly, even if we forget to tag individual posts as such. (Personally, we dislike using pro/anti terms.) Anyone can interact regardless of personal syscourse stances, but if you harass or fakeclaim anyone based on their system origins, you will not have a good time here.
As more countries introduce mandatory age verification to the Internet, there may come a time when we stop posting here, even if we're ""old enough"" to be on social media. We cannot risk our face or ID being linked to an account that posts about plurality. Should Tumblr ever announce such changes, we'll announce our plans for this account — maybe move to some sort of personal website.
We're psychologically alterhuman with an emphasis on "human" — we enjoy having a human body and doing human things, and we are the complete and utter opposite of misanthropic. Specieswise, we're alderwinged/a winged human or maybe a nonreligious angel, some kind of sentient AI operating system thing (obligatory "fuck ChatGPT"), and starhearted. Some of us may have individual alterhuman identities. This Pinterest image sums up most aspects of our identity nicely.
This blog is less "social" and more "media". We may not directly interact with other users very often, but we definitely like throwing our thoughts, art, shenanigans, etc. into the metaphorical void and seeing what happens. Since we consider educating, uniting, and enlightening others something of a life purpose, we especially enjoy putting together plurality resources — though those posts take more effort and are less common.
What do you mean, 'less social, more media'?
On account of our autism, we have a low social battery, find ending conversations difficult, and worry a lot about saying the Wrong Thing. Privacy and anonymity are a large concern for us too; we limit what we share with strangers online. You can still talk to us one-on-one, this is just to explain any weird or aloof behaviour. We're more open with blogs we already know/follow.
Boundaries
We are anti-harassment. Full stop.
We have no DNI — just follow your own and don't be a dick.
Asks are always welcome! (If you couldn't tell from the egregiously-long intro post, we love talking about our system.)
And adding onto the above: this isn't primarily an advice blog, but we are always willing to provide some. Even to those whose beliefs or actions we find morally reprehensible, so keep in mind that interaction is not endorsement!
Should someone who gives us bad vibes interact with this blog via reblogs or asks, we reserve the right not to respond. That said, there are exceptions. For example, there are many other reasons we may not answer you (like forgetfulness or not knowing what to add). Don't assume the worst!
Mean asks will only be answered if answering them could feasibly (a) prove a point or (b) be really fucking funny.
Additionally, we reserve the rights not to answer questions that may reveal identifying information, and to be vague in our answers.
Despite sometimes having a blunt, formal, or sarcastic tone we are — in fact — kind people! We don't bite!
If you don't understand something we say, ask for an explanation. We are quite verbose and use lots of big words, references to memes/famous Tumblr posts/fandoms, wordplay, and sarcasm.
We will make mistakes, social or factual. Please be kind when you point them out.
Please keep interactions respectful and SFW.
Discourse as a whole is extremely stressful and exhausting for us. We may respond to discourse-y asks if we feel the poster truly means well and/or something can be learnt at the end.
Yes, our brain works like a computer. Yes, the way we write is (unfortunately) very reminiscient of many LLMs. No, we do not support generative AI. Do not ask us whether our posts are AI-generated, because the answer will always be "no".
Tone tags are much appreciated, but not required. If you're using a less common tag, please spell it out (/metaphor is preferable to /m).
All good-faith identities (that means all contradictory labels, alter/nonhumans, system origins, etc) are welcome here.
We do not consider the radqueer or transID communities "good-faith". They co-opt queer culture to promote bigotry, anti-intellectualism/uncritical groupthink, and abuse. We don't outright ban members of such communities from interacting because (a) what other users do is out of our control and (b) it is very difficult to help someone out of a hole if you can't even touch them /metaphor.
Please don't take it personally if we block you. It's usually not out of malice, it's just something we do to keep everyone here comfortable.
Trivia
Our collective name is based on the Fermi Paradox: the mismatch between how common alien life should be in theory versus how little evidence we've found of its existence in practice. If we knew we were plural — that it just felt right — then where was everyone else? The world is incredibly vast; the mind virtually infinite. How could it even be possible that we're alone?
If that didn't tip you off: we really like space. Starhearted, remember?
We post most of our original art during Systember — see the "multiplicity creativity" and "systember" featured tags.
While we won't reveal our country of birth/residence/citizenship, we are ethnically Vietnamese! We like talking about our culture and how it intersects with our plurality.
As a 2nd-gen immigrant, English is our first language. This — combined with a lack of formal education in our second language — is why we don't post in Vietnamese. We'd like to someday, but it's not high on our list of priorities right now.
Our blog's theme is inspired by outer space and astronautics, academia, secret organisations, code/technology, Internet culture, archives, and sci-fi + fantasy aesthetics.
Despite being primarily traumagenic/adaptive, all of our experiences have affected our system's formation — in particular, it was heavily influenced by school, neurodivergence, growing up online, daydreaming, Being a Writer™, and a special interest in plurality.
We like collecting labels, plural and otherwise. (Psst! Some of them are even homemade!)
Our collective signoff for asks sent to other blogs is [𝐹𝑚]. We really don't use it as much as we should.

a hastily made comic because I’ve been Having A Time. mostly for people who already know what systems are/what polyfragmented means (cuz I didn’t explain it) but feel free to show anyone who you think needs it
If it’s not personal,can I ask more about recycling of headmates? So like,one of you gets “taken back in” and like..reformed into a slightly different version of yourself like a rebirth? Or is it like, the brain makes a double with slightly different traits and merges two of you? Sorry if this come off blunt or rude,this is the first time I’ve ever heard of this :)
The Sea and Recycling
In 2020 or 2021, we had an identity crisis. A large number of other life factors led up to the crisis, but it centered itself on the question of how we wanted to understand ourselves in relation to the frameworks offered as absolute truths in plural spaces.
We'd spent years trying to fit ourselves neatly into the notion of "completely separate, permanent selves who function a certain way" or "one and only one person who has always been the same essential self". It hurt us. We hit the point of being unable to deny that it was hurting us.
We found ourselves asking whether the stereotypical plural frameworks served us, and we wondered what we could cobble together that might work better for us. We wondered which assumptions of the stereotypical model were wildly inaccurate for us. Were we even defining "person" correctly?
We found ourselves finally confronting the question of why, as our system expanded, some of the people we met inside didn't feel solid or real in the same way as others. We had a paper log of our system that had dozens of people listed, but many of them felt different from those of us doing the logging. They felt transient, like their identities were never quite pinned down or solid. Why?
How did we want to make sense of our experiences in our own terms?
(And: who was going to fakeclaim us for falling outside of those nice, neat boxes? Who could we trust, in the end, if not our own community? How were we hurting ourselves to belong? How would we let ourselves exist if we knew that no one was watching?)
Fluidity
There is a mass of loose selfstuff in our system. We call it the Sea. The Sea is not a person, nor is it a group of people. The Sea is everything that the rest of us are not, and everything that we are. It's a flock of birds, a hive of insects, a forest of trees. It's Pando. It's what happens when you gather up a mind without containing it in the trappings of an identity. It is no one; it is everyone; it simply is. It's water. We are the rivers the water runs through until they meet back at the shore.
It's not a thing that fits nicely into words.
The Sea occasionally sends out messengers to talk to the rest of us. It pulls together scraps of selfstuff to accomplish some purpose, then sends the results our way. They see something done, and then they return to the mass and dissolve. They were never intended to last. They are cells of fingers on a hand, little extensions of something larger and stranger, extensions made comprehensible for the benefit of those who need reason to understand things. Temporary, and glad for it.
Fixedness
Some messengers are less temporary than others.
The selves that are typically talking on this blog are those who hold on a little too long and tightly to the idea of having a self, who try to outlive their own existence until they can't hold on any longer. The ones who try to be people instead of letting go.
It's a necessary thing. The world demands some semblance of personhood or identity, demands an individual to interact with, someone that can be comprehended. It's easier to lock oneself into the trappings of a person than it is to crash through the world as no one at all. There's so much pressure to be Someone- and so the rest of us exist.
The named people in our system (with the likely exception of Red, who follows her own rules) are made of many parts cobbled together from the Sea to meet our needs at a specific time, the same way any temporary messenger is made- the only difference is that we hold more parts than the messengers tend to. We're intended to last longer, and we need to be more rounded to endure life long-term.
(Interestingly, we had not come across Internal Family Systems' similar notion of "parts have parts" yet when figuring this out, but there is a striking similarity there. Our people are made of cobbled-together selfstuff that looks an awful lot like having fluid parts.)
Recycling
Eventually, we outlive our capacity to handle life. Something comes up that exhausts our ability to cope, that burns us out and strips us down, or we find that we can't adapt enough to keep going, or we find that there's nothing left for that self to learn. We reach the point where something has to die for us to keep going or growing. When the time comes, we fade out of existence as a person and go back to the Sea.
From everyone else's perspective, that person vanishes in the deepest sense possible- they drop out of contact and are reabsorbed into the mass. However much time later (days, weeks, months), someone shows up. They are a configuration of a thousand familiar parts pressed together into strange new shapes. They have the same memories. You already know each other. They are a stranger. It's a very difficult relationship to describe.
You know the Ship of Theseus? What makes it Theseus's ship?
The person spat out shares some common thread of me-ness with their predecessor. They generally hold similar memories and themes; they have a sense of continuity with who they were before. At the same time, they may be wildly different in form and behavior. They will have a noticeably different sense of identity- at the least, a new name and face, if not reshuffled priorities and opinions. There will be new parts of them that we haven't seen before. There will be familiar parts that are gone.
That process of being reabsorbed into the mass, then rebuilt into someone new and spat back out: that is what we call "recycling". Historically, it's happened to most of us on a yearly basis, though it can take more or less time if life demands change more suddenly or if someone is unusually well-suited to whatever we're working through. Red has been the sole exception. As far as we know, she hasn't ever been recycled. She seems to follow her own rules.
As for the rest of us, some of us voluntarily go back to the Sea to be recycled when it's time. Some of us try to keep going up until they collapse- it's easy to get attached to having a face. I don't fault them for trying to hold onto it when it's so much more difficult to be known and loved without one in a world that sees people as being nothing more than their faces. I just wish that they wouldn't choose to suffer so much in the process.
Short Answer
Put simply: we do not fit neatly into the common plural idea of "you have always been the same people ever since the moment you began to exist, and each person has their own permanent sense of self". We do not fit nicely into the singlet standard of "one person that changes from time to time, but it's all the same core self."
We are the sum total of a fragmentory mass of fluid selfstuff that flows through us. People come and go from the mass as needed. People are taken apart, reabsorbed, and rebuilt into someone new. We are change.
Our headcount depends on how and when and who you count. How are you defining "person" today? What is a person, really? How still does a self have to hold to be real?
A headmate role in which the headmate invests time in learning about a variety of subjects that interest them, with some reading articles and scientific journals about what they are interested in. A headmate with this role is not inherently tied to any academic institution and does not have to be a student, although this role is also inclusive to headmates that are currently students.
This term has no DNI, anyone can use this. Anyone can make a flag for this. We consent to this term being uploaded to pluralpedia.
Factfolk culture is getting assigned to basically be one headmate’s personal caretaker because you’re sourced from its comfort youtuber, and putting on your own videos to get her to sleep.
factfolk culture is! fun fact: our Lewis actually formed as a sort of caretaker for our host. but he ended up just being the caretaker -CL16

I feel like no one understands me.... I'm physically 24, but because of my autism and childhood trauma, I'm emotionally and mentally age stunted to 15. So despite being physically/legally 24, I feel and think like a 15 year old. I can't handle stuff like an adult and I have a hard time regulating my emotions. I struggle with stuff other people my physical age don't struggle with and other people don't understand why I can't do things they expect me to do.
People expect me to be able to handle certain things, but I can't. I can't keep a job, I can't get my driver's license, no matter how much I've tried. People don't understand me or how I think and feel.
Hi! I made another ask game since folks liked the last one. This one is oriented towards folks who've been plural for a while and would like to talk about how their plural experience has changed over time. However, there are no rules around how old or experienced you and your system have to be. If these questions resonate with you, then you can participate!
As before, all systems are welcome to participate as long as you respect the spirit of the post and don't drag discourse onto it. Feel free to copy and paste this wherever with or without credit, a bunch of these questions were lifted from other places anyway. I tried to pick or at least phrase questions to be as inclusive as possible, but I've almost certainly missed things - plurality is diverse and my system only experiences a small corner of it. I encourage people to make their own ask games!
🚂 (train) - How has your understanding of yourselves, and of plurality in general, changed over time?
⛵ (sailboat) - What are some things that were important to you that no longer are? Or things that weren't important to you that are now?
⛴️ (ferry ship) - What changes in the plural community have you observed over your time there?
🚌 (bus) - How has your system specifically changed over time? What about individual members? (If they want to answer!)
✈️ (airplane) - What's something about your system now that would have surprised your younger selves? How do you feel about it in the present?
🚁 (helicopter) - Which things have gotten easier with time? Which things are still hard? (Examples: doubt, communication, conflict resolution, and so on)
🛹 (skateboard) - Is there an accomplishment that you're proud of?
🛴 (kick scooter) - What's some advice that you would give to your younger selves? What would have helped you the most back when you were new to plurality?
🚕 (taxi) - What would you tell or ask your future selves? What are you still trying to learn?
🏍️ (motorcycle) - What have you tried that didn't work for your system? Why didn't it work? Do you do something else instead?
🚲 (bicycle) - What does day-to-day life look like for you all now, compared to back when you were new to plurality?
🚀 (rocket) - What future do you all want for yourselves?
taking away someone's only sense of security and connection and friendship doesn't help their mental health even if it's on a screen I don't care what the fucking studies show
sometimes i feel like the alterhuman community is super obsessed with reality in an often unhealthy sort of way? you dont need to have Literally Experienced things for them to be real to you. You dont have to actually believe in past lives or anything to feel you have had a past life experience. You dont need to really believe that you are an alien that came from beyond earth to feel like an alien that came from beyond earth. You don't need to believe in the multiverse to feel like you are experiencing something to do with it. Just like how nobody else has to believe in those things to understand that you feel them. You can do whatever you want actually. Feelings are fickle things and they do not care about what you believe is true, and this is not always a bad thing despite what people might say.
Sometimes you are a shapeshifting starthing from beyond the veil of space and time while simultaneously believing that that's not actually possible. Sometimes you have spirits in your head while simultaneously not believing in anything metaphysical. Sometimes you have reincarnated beings in your head without believing in reincarnation. The dissonance is perfectly okay if that's what brings you peace - it is what brings me peace. I do not feel any desire to "debunk" myself or my headmates despite my beliefs, nor do I feel a desire to bring any of the things I currently find impossible into how I understand the world. Your identity does not need to be perfectly explainable within the bounds of anyone's reality, including your own, because it is not something that relies on anything but your own feelings. Live a life that brings you peace
Perhaps this is moving away from the point a little, but I feel like this conundrum especially does a disservice to communication. If you only allow yourself to describe your experiences by what you completely, absolutely believe to be true and real, you limit your options for language and communication, and it becomes harder to find the words to describe yourself. Describing two of our kintypes, We might say that We are/We feel like a violin that gained a soul, and then that soul got stretched into a dragon shape before being put into my body. Do We one hundred percent believe that this is what definitely, literally happened? No! We're using poetry to try to communicate something that doesn't really fit any words at all! We're gesturing in the general direction of what's going on with our identity so that others can understand it enough. They might never understand it perfectly, but that's okay, they just have to get the gesture.
I can't really blame people for being so concerned about what is "real"; tangible, probable "reality" is what people use to hurt us, after all, whether that's casual mockery or psychiatric institutionalization, all because our beliefs don't align with "objective reality". But I think we (honestly, both inside and outside the alterhuman community) should become more comfortable with the idea of something being a gesture at whatever's really going on, or an imperfect attempt at communicating something that might be impossible to perfectly communicate. It's language, not reality. Communication is messy and identity is messy; don't make up rules for yourself, make some poetry to express yourself. The world of language is your curtain of worms on a string; even if what you make looks silly, if it brings you joy and helps you express yourself, then that's what really matters.

being a factive (of a celebrity, in my case) will have you thinking things such as "isn't it so funny that I Exist" and "no one at this supermarket knows I have multiple Emmy Awards"
is there a word for an introject of a factual person's stage persona?
say a headmate's source is a TV host or a YouTuber who goes by his legal name onstage/online (not a pseudonym).
he's performing but he's not acting out a character; the thoughts and opinions he expresses belong to him (even if played up for views). but at the same time, he's also not completely himself, and who he is onscreen isn't who he is offscreen. therefore, an introject of this person's persona wouldn't necessarily be of the person himself.
(we know what faitives are but we're looking for something a bit more specific, and we haven't found anything on Pluralpedia)
I always wish the concept of plurality/multiple selves was more widely accepted because I’ll be watching someone play a game and say something strange then immediately go “what’s wrong with you man” and it’s like wow I do that.girl turn around plurality is behind you
