Post Apocalyptic Fantasy

So, an idea I have been brainstorming for some time now is a modern world (either our world or a fictional analog) experiencing a global cataclysmic event that causes societies everywhere to collapse.

After awhile, things settle down. The apocalypse is still recent enough for people to be dealing with the effects of the cataclysm, but whatever caused it is no longer an active threat to the current inhabitants. Some rebuilding has occurred, but things will never return to the same level before the apocalypse.

The basic theme of the setting is a mish-mash of tech levels, as is standard for post apocalyptic stories. I'm thinking of making it Medieval at its base, but more Dark Ages instead of High or Late Middle Ages.

Instead of knights in shining armor, most soldiers wear leather, gambeson or lamellar, maybe wirh some more modern material and equipment mixed in. Most people are gonna be armed with swords, shields and crossbows. So, no firearms.

The castles look more like the motte-and-bailey style fortifications rather than your standard stone castles you typically see in fantasy.

As for the anachronistic tech, I'm thinking of allowing more "primitive", for lack of a better term forms of tech. Sure, there's no Internet, but nothing's stopping people from using type-writers again. There also might be limited electricity created by hand-crank generators and maybe even a telegraph system.

Some fantasy stuff is gonna be harder to incorporate, especially if it's supposed be set in our world. I am leaning towards alchemy, as I feel like it would be the least jarring kind of magic in a RL based setting. I kinda see alchemy as "proto-science," or the science before we had science. Then again, one could opt for the "sufficiently advanced tech" route.

I think fantasy races could be easily explained as mutants. Initially, I had a race that were basically uplifted mamals like wolves and bears, but changed my mind as that's probably straying too far into furry territory, and that's just not what I'm going for.

Perhaps the biggest issue with the setting is believability. I'll admit it's probably not very realistic for everyone to go back to living like they're in the Dark Ages, as opposed to maybe more lare 1800's or early 1900's, but I like the aesthetic. It's basically Medieval stasis with a post apocalyptic twist. I am leaning towards using bullets and other ammunition as the world's primary currency, mostly as a way to justify the lack of firearms (since firing a gun is basically burning money) but I also feel like at this point after the apocalypse, some kind of coin or banknote would eventually be in circulation.

I'm still undecided about what caused the apocalypse, but leaning towards asteroid impact, volcanic winter or good ol' reliable nuclear war. Or, now that I think about it, perhaps a pandemic would be most fitting so there could be parallels with the bubonic plague and portray history as repeating itself.

One important thing with regards to believability is the question, could we reinvent everything we have today simply because we know it exists?

The answer, very likely is no. Just think about your own situation, could you build a computer with nothing but your hands as tools? Or a car? Or any of the million machines we use to either create stuff or create other machines? Or any of the raw materials?

A second point to consider is that we already got all the easy stuff out of the ground. If we had to start from scratch again, getting a second oil boom going would be very, very hard. In the early years of needing oil or coal, the stuff was almost just lying around, flowing from the ground. Today? Not so much anymore. Same with all other raw materials like metals. The only way we still know where to find the stuff is because we have very advanced machines and we know where to look and how to get it out.

Just imagine that you have no electricity. Would you search for oil at the bottom of the ocean? How would you even go about that?

Most people are gonna be armed with swords, shields and crossbows.
Small sidenote: most people would not be armed with swords. Swords are expensive to make and aren't the best at almost anything. A guy with a spear would most likely beat a guy with a sword in many scenario's. And you could probably arm a whole batalion of people with a spear compared to creating a single sword.

As for crossbows, they only became popular in later middle ages (11th century and later), which is after the period you have in mind. That's not to say you can't have them of course. The chinese had them 15 centuries earlier. It's just that they don't fit in the period.

Well, you might not be able to make a computer, but don't underestimate what you can achieve with just access to the sort of twenty year old textbooks you can find in a college library.

Yeah, I fear this one would get me asking a lot of questions. If I could get electricity by hand cranking, I can probably invent a water wheel to do the cranking for me. And after such an event, its far more likely there will be a lot of guns just laying about than crossbows. Many people, especially survivalist types, know how to make bullets. If they have bullets for currency...

Somethings might be lost, who knows how to do math without a calculator anymore? Course, there are a lot of solar powered calculators about. And why build a castle, surely there must be some buildings still standing that could just be confiscated for the role. I am playing Planet Crafter, and it is kind of silly that I have to make my own base, when they world already has abandoned stuff on it. Why not just use that one and call it a home?

Internet, satellite communications, the ability to build a smart bomb, rocketry, refining fuel...that stuff may take a hit. But a lot of stuff would remain. It would have to be truly devastating to knock us back to crossbows. I am not sure we could even survive something like that.

You have a tough sell. But then...fiction and good story may over come it.
 
I know there are some anachronisms, like the crossbows, but that's deliberate since post apocalyptic settings are often inconsistent in the level of technology. It's kinda the point (and part of the fun) of the genre.
 
It really depends on what's left standing after the appocalypse. And yes, old textbooks help. Though a lot of those still assume a basic level of having stuff available. Yes, you can get electricity by hand cranking, but what if you need to make the wires to create the dynamo? How would you go about that without modern technology? And of course, what use is that actual electricity without a machine to power?

The more stuff and knowledge remains, the easier it will be to rebuild parts of society. Which is very much comes down to what happens during the appocalypse. But if you already start with a solar flare that wipes all electronic storage, then an awful lot of knowledge would be gone. Find a way to burn libraries, and take it from there.

If you want to get an idea of what it would take to rebuild, check out the How to Make Everything youtube channel, where they actually try to reinvent everything, starting in the stone age. And it turns out, a lot of simple things we take for granted are bloody hard to achieve.
