System classifiers (the key ones, at least):

[Our system boundaries]
[Frequent posters - will update regularly]
[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.
🏳️⚧️: Who's got the MOST pronouns? (You don't have to list them of you don't want)
Honestly? We're pretty boring when it comes to pronouns; the majority of us just stick to one or two sets for convenience. Jericho probably has the most (she usually goes with she/her insys, but is also cool with any neos that fit her Vibe™. her gender and pronouns are the problem of whoever happens to be talking to her.)
🤠🏴☠️: Let's ask the real questions. Pirates or cowboys?
That's a good question. It's close, but as the current fronter I'm going to say pirates, just because of the higher fantasy worldbuilding potential and also YAYYY TREASURE!!!!
👽: Put the alters on a scale from The Creature to A Guy
Already done! Graphic design is our passion etc etc. This only includes system members who are currently here.
First English version of the International Plurality Handbook is out!
This is a compilation of plural resources for systems in countries all over the world. Copying, translating, replicating, and recreating in different formats is not just allowed, but encouraged.
All we ask is that you notify us when your translation is complete, so we can link it to the original document.
It features:
an explanation of what plurality is,
a list of websites and individual articles, organised by language (of which there are currently 10),
academic papers on plurality in different regions of the world,
and a few tips on explaining plurality in your language or culture (we are hoping to add more).
Despite the original version being written in English, it is written in plain language (no figures of speech, bare minimum jargon with explainations) so that those using tools like Google Translate can get a clear idea of the information.
This guide is not perfect! We are only fluent writers in English, and we do not have insight into every single culture. It will update as new resources are found.
If you have any tips, links, suggestions or complaints, send asks to this blog or email us at [email protected].
Securely store, share, and access your important files and photos. Anytime, anywhere.
there is next to nothing in the documents about Metaphysical, Cosmagenic, or otherwise Gateway types of Plurality. It almost feels as if this document is trying to push the psychological and western views of plurality whole erasing anything considered Non-Brain made Plurality.
Where are the mentions of Collective members NOT residing within the brain? Why is plurality always "multiple selves within a body" and never "plurality is a body used/shared by multiple people" without the literal implications that the ONLY way is for the entire collective to be "within" the brain/body when that is not ALWAYS the case?
I know this is probably meant to be a "brochure" type of document, but that almost makes it WORSE because it further pushes the idea that Metaphysical, Spiritual, Cosmological, Soul Bonder, etc type of plurality are less than or just generally don't matter. If we want the community to be more inclusive, then those who wrote resources like this have GOT to start including those lesser known and often shoved aside and ignored forms of plurality as well. They're probably only "lesser known" because no one gives them the time of day and so when new people discover their plurality, they're basically spoon fed psychological models and never get a chance to discover anything else for themselves.
It brings to mind how children are "raised" off Heterosexual normative and are rarely, if ever, exposed to other types of sexuality or romance because their parents think it's bad, immoral or something. It's almost like the plural community is trying to "hide" these other forms so that new plurals, or even older ones, won't explore and dabble in that "crazy" rhetoric.
I know this was originally intended as a vent post (and ergo, was probably not written to invite a reply) but genuinely: thanks for pointing out the oversight. You bring up some great points here.
Looking back, it was quite hypocritical for us to go so hard on the "inclusivity" angle while neglecting to mention metaphysical and spiritual models of plurality — especially when many cultures worldwide have spiritual practices that are at least plural-adjacent.
We'll make sure to take metaphysical forms of plurality into account when we next update the guide (by including actual examples/explanations, and rephrasing our explanations of plurality so that they don't exclude non-psychological frameworks).
However, we don't want to risk (for lack of a better term) filtering everything through our own perspectives again.
Should any of you decide to offer feedback, it'd be an honour to hear what you all have to say. If you decide not to, or if you aren't able to, we open the floor to other metaphysical plurals.
What specific changes would you like to see in our next updates? (e.g. certain identities/labels/experiences, links to articles and studies on those identities/labels/experiences, rephrasing of other sections, etc)
👽: Put the alters on a scale from The Creature to A Guy
Done! We've had lots of headmates come and go in the past, so we chose the ones who are currently present. Click to see the text in higher quality
☕️: How does everyone make their hot chocolate/coffee/tea?
As far as we know, none of us make our drinks very differently from each other. If we don't have hot chocolate mix (which is most of the time), we just melt some plain chocolates into a teaspoon's worth of milk on the stove until it's smooth, add the rest of the milk, and add sugar, a pinch of salt, and vanilla extract to taste. We don't really drink coffee that often, and for tea we just. put the teabag in hot water lmao (a lot of our teas are fruity and not meant to be drunk with milk)
💻: Have/would you(current fronter) put any fellow alters in Tomodachi Life (if you don't have the game, consider this a hypothetical)? Why or why not?
If we had Tomodachi Life, we absolutely would. I think it'd be really fucking funny to study our game-selves like specimens in an enclosure and/or participants in a reality TV show. And we wouldn't have to think of new characters specifically for the island.
🧍♂️(standing man): If y'all have a singletsona, are they moreso based on one alter, or the collective? If y'all don't have a singletsona, imagine y'all had to make one? Would it be based on one alter or the collective?
Our singletsona is based on Fermi (the host, who Cannot Leave) and the body's legal identity. We don't actually put that much effort into hiding our personality changes, but we do have a sort of "safety mode" we present around certain groups (for example, around family this means keeping our head down and sharing very little).
Welcome to our ask game! Wei made this in order to force ourselves to interact with plural community, and hopefully make some plural mutuals/friends! SO for every single person/system that reblogs this post, wei will send them an ask! That's right, every single one! AND if you send a screenshot as proof that you've sent someone else an ask, wei will send you another one! That's right, another one! So remember to be polite and send an ask to the person you've reblogged from! (Excluding meus unless you want to, wei would love to answer of you do)
Notes: Wei've used 'alter' instead of headmate due to personal preference. Wei used 'y'all' to refer to the system and 'you' to refer to the current fronter. When wei say "everyone" or "alters" big systems feel free to only do a few alters. Obligatory only answer what y'all are comfortable with

A lot of gear suggestions aren't conducive with workplace or school dress codes, might be unsafe for some, or just aren't everyone's style. Here’s some ideas for understated nonhuman expression that's not just "wear a graphic print".
If this post inspires you to buy anything, please shop secondhand where you can!
CLOTHING
Fabric choices - Animal print or fur isn't the only option! Focus on which textures you associate with your ‘types. Maybe you like heavier fabrics like wool or leather, wrapping you in a protective layer. Maybe you enjoy the lightweight feel of silks and linen that flutter in the wind. Maybe the structure of sturdy denim feels like a chassis. What feels right against your skin?
Cut - This refers to the shape or style of a garment. What silhouettes read as your ‘types? Maybe you want to add bulk via a boxy blazer with shoulder pads. Maybe sleek, straight cut trousers or a pencil skirt is more you. Look up cuts of jeans if you're new to this and want to start somewhere!
Socks - Maybe they're full on novelty socks, maybe they've got hoof prints on the underside. Fun and subtle!
Shoes - Big platforms or steel toe boots might remind you of hooves, or running shoes can keep you nimble and quiet on your toes. From an aesthetic standpoint, pay attention to the colour and textures. Maybe a brown suede reminds you of your paws, maybe metal hardware reminds you of your shell.
ACCESSORIES
Watches - These could be subtle, with just a strap colour your associate with your ‘type, or a full on statement piece that looks like alien technology. I picked mine because it reminds me of a cat collar.
Cat collar bracelets - Speaking of, these just look like leather bracelets and are a hell of a lot subtler than wearing a dog collar!
Glasses frames - Does the shape of your frames feel insectoid? Round and owl like? Qquare and boxy? How do they transform the shape of your face? Of course, a relevant colour or pattern is also an option!
Pins & Brooches - These could be colourful enamel pins or small simple vintage brooches. Wear them on your clothes or bags.
Belts - This can be a great place to introduce heavier textures like reptile skin or suede, or you can go the opposite direction and use fabric or rope. A statement buckle can be a fun addition if you want to get a bit flashier!
TL;DR Thinks about these two things: what feels right in a sensory way (good textures, lines up with phantom shifts) and what looks right to you (colours, patterns, how fabric sits on your body).
sometimes various aspects and functions of your systemhood can be heavily related to topics that are usually to be censored or not to be mentioned at all. you are absolutely not alone in your experience, and you will find people who are genuinely interested in hearing about your system in an unrestricted manner. you existing as your most honest self is an experience you have a right to, and not being able to do that in most spaces says nothing about who you or your system is.
hey uhh. i know i&+ advocate for source memories being valid and they are! i'm just. having issues with my own source memories. especially if like i didn't think it happened to the body but i'm not sure and i don't want to be taking things from real survivors and. are there lines that i'm crossing with this? i've heard trauma can be anything—if it changed you in a negative way, it can be counted as traumatic. but... i don't know, for some reason i'm thinking this "isn't true" or...? i'm not sure. sorry this is jumbled. can anyone share what they think? /nf /genq - [🗡️] (he/it)
i highly recommend developing an intense interest in some natural phenomenon or creature such as bugs or stars or mushrooms. you will be delighted every time you go outside
