Here are some OFF headcanons centered on elsens that nobody really requested but my friend and I wanted me to write teehee ^_^
Elsens in Zone 2 are really nosy and gossip-prone. However, it isn't malicious-- it's more oriented towards keeping the community safe and alert. In fact, almost all of Bismark is aware of who has damaged what books, besides the Librarian of course-- the culprits are already at risk of getting themself papercuts, it would be so cruel to also get them in trouble too.
Elsens in Zone 3 have a very competitive and toxic work environment. When one elsen succeeds, another elsen is punished. Rations certainly aren't coming out of Enoch-- no, Enoch has it arranged that for every percent increase in rations that one elsen earns, there's a percent decrease for a less productive elsen.
Elsens in Zone 1 have a very cooperative and supportive work environment. The success of one elsen in a district is treated as an inspiration and something to model for the rest of them-- especially if that success gets noticed by Dedan. Dedan might be a loud asshole, but he knows how to make a productive work culture at least-- if only there were clones of Dedan like there are of elsens, he'd be a lot less stressed and pissed off. And unlike in Zone 3, Zone 1's elsens have some days off.
Elsens under the effects of sugar are referred to as "glazed," as opposed to "high" or "stoned." Additionally, that one elsen in Area 1 of Vesper whom we see looking out over the plastic sea was definitely glazed.
I see a lot of people think that wearing the necktie made The Batter be visually perceived as another elsen, but I disagree. The Batter didn't trick the elsens of East Bismark into thinking he's an elsen by wearing a necktie per se; what wearing the necktie really did was give them a sense of security in thinking that somebody there knew the Batter personally and let him borrow their necktie as a way of vouching for him to travel through. That vouching went right out the proverbial window the moment that the Batter began making the elsens there feel ill at ease though.
As a follow-up to the previous headcanon, I also like to think that-- although the valzong-burnt sprite and the overworld elsen sprite stay generic-- there wasn't actually a real prize to winning the Balloon Game in Zone 2's Theme Park, but the elsen in charge of the game knew that prizes were typically rewarded upon completion of those sorts of games, so he'd take off his necktie everytime he had to work the booth just to fix it onto the balloon in the middle. He never imagined that somebody would actually win that prize though, which is another part of why he was so freaked out (and the sound of the balloons popping certainly didn't help his nerves either, even he did know the source.)
Liquid plastic is occasionally referred to as water by the elsens-- primarily the ones of Zone 2 who've read about water in certain books, and then related the concept of water to the liquid plastic that they've got instead. Liquid plastic is not something you want to get on your skin though, and even less, ingest. But you'd find it in the same places you'd find water, so it works out. Reading about touching or ingesting water in books freaks elsens the fuck out though-- combined with the fear of ripping pages, the library might as well be considered full of horror novels.
Elsen clothing is all made of polyester. Thankfully, elsens don't really emit body odor (even when they sweat), though they can accumulate a general funk from where they've been, which they do wash off with a nice metal dust bath. The exception to this is that elsens under immense stress and on the verge of going burnt do have a very slight smell of caramel about them. Burnts themselves have a very strong smell of charred caramel. On that note, the air in Zone 3 can be like a horrible punch to the nostrils to anybody not from there-- especially the farther North in Vesper you get. Sugar consumption can make the sugar smog more tolerable though.
Most elsens do their laundry communally, but some (mostly in Zone 2) prefer to do their laundry themselves and at their own pace. Honestly, everything happens at its own pace in Zone 2, besides trade with the other zones.
Most residents of the Zones, including elsens, make up for a general lack of water by getting all their hydration needs met through consuming meat... Somebody ask me my thoughts on Zone 1 cows please.
Zone 1 elsens tend to stay in their assigned districts for long periods of time, with various promotions scattered throughout. However, if an elsen is starting to become disillusioned or even burnt out with their current stations, there is a process for them to start anew in a different district (though it is lengthy)... Unless they're in Alma, but who would want to leave such a good job?.. Under normal circumstances, your average Shachihata worker can take years to become truly worn thin by their job, but in Alma, it usually only takes a month for the disillusionment and anguish to set in. This is why everybody but those who actually work in Alma sing Alma's praises so high: dead men tell no tales. And a month is not long enough for an elsen to completely deconstruct their preconceived views on Alma (and warn others of the pipedream)-- they'd much sooner just straight-up burn from the sudden influx in disappointment and doubt.
Also, this is not my own headcanon, not at all, but I am 110% a believer in that all the elsens originate from the giant elsen in the Room, forming on that guy like fungus on a log and then falling off... Onto something a bit more original to that though: the other elsens we see in the Room are in direct contact with the big elsen and-- along with having very streamlined, simple routines-- that's why they're so steady and confident. Meanwhile, the vast majority of elsens elsewhere had been taken from their progenitor so quick they can't even remember him, and they remember the Room just barely. So they couldn't even develop that essential part of identity that comes with having a connection to any sort of nurturing figure, though many in Zone 1 have imprinted on Dedan. A few in Zone 3 exalt the Director like that too, though much less directly, and it's almost always from those who have never met the Director. But then you've got the elsens in Zone 2 who've got no guardian that they know of-- no protection nor leadership... Japhet, unlike Dedan and unlike Enoch (who views the elsens more like peons), returned the feeling of kinship though-- which is not so much headcanon as it is canon actually haha.
