I write an Isekai about communist revolution until an anime is made out of it

The Beacon of Amlenian the Magnificent

After a few days on the road, our little caravan made its nightly stop in what was by far the largest town I'd seen since leaving Morgenheim - a place called "Amlenian city". As I had the past few nights, the moment the carriages stopped I left the party (whose names I still didn't know), scarfed down the fastest dinner I could find, and locked myself inside my room at the inn we were staying at to continue my pet project of jotting down the history of the earth until  I was exhausted enough to sleep.

Before I could complete the final step of my elaborate plan, though, I was jolted from my trance by a knock on my door. It was Sylia, demanding that I go outside so she could "show me something". Before I had the chance to ask what "it" was, she had grabbed my hand and yanked me out the door. Out of pure instinct, I put my weight into yanking it back, while with the other hand I drew the revolver that hadn't left my side since the moment I picked it up.

"What the hell are you doing?"

She was visibly shaken by that response, and for a fleeting fraction of a second I felt regret looking at her frowning face. I gathered my composure, holstered my gun, and asked:

"What's so important that you need to drag me off to see it?"

"The beacon, I thought you'd like to see the beacon."

"The what?"

"Can you just go outside, please?"

"That's it? You know, you could've just asked."

With that, I sighed and walked past her to leave. I had hardly stepped out the door before the night sky was ignited by a column of white light rising up from somewhere nearby. Everything in sight was illuminated by the column's surreal white light, casting long shadows across the street. I could see the locals standing in their doorways to squint at it, and I began to join them. In a few more seconds, Sylia was standing beside me to deliver a monologue.

"this is what I wanted to show you - The Beacon of Amleinan the Magnificent. This is what a life well-lived looks like: it was more than a thousand years ago when he built this masterpiece to secure his legacy forever. I figured that you don't really understand that concept considering how different your world is, so I thought you'd need to see it for yourself."

For the first time in over a month of being isekai'd, I actually had a good, long look at her face. It was heart-shaped, and her skin was more than light enough to pass as "white". The problem with that distinction was that she didn't quite look "white"; her face was subtly shaped in a way that didn't quite match anybody I'd ever seen, or even imagined. The most striking feature, though, was the narrow tops of her ears, as if someone had whittled down the curved top of a "regular" ear, except this looked natural. Altogether she looked like a new race of human being; maybe what the people of Atlantis would have looked like if Atlantis was an actual thing and not just tall tales about the Minoans.

Had I really gone more than a month without realizing she was part of a new race? Running a hectic trail through my recent memories, it occured to me that everyone I'd seen since being isekai'd shared those features. Everyone here was a different race from anyone on Earth, and somehow I had only just noticed. Honestly, not a good sign.

Great, everyone here looks slightly different, there's some giant fucking laser beam right there but no, I've got to look at how the people are all barely different. Well, better now than never, I guess.

What even is that thing, anyway? If it was just a laser, wouldn't it also give off lots of heat? Actually, I think I read somewhere once that one of the technicians in Chernobyl when it blew up saw a beam of light coming out of reactor 4, because of the radiation in the air refracting light or something. Well, if it was radiation, they definitely wouldn't be able to build a city around it, so maybe some other atmospheric fuckery, then?

At that point in my pondering, the beacon stopped. It didn't fade away - just disappeared in an instant, like shutting off a lightbulb. Sylia had turned to admire the beacon as soon as she was finished talking to me, and now that it was gone she turned back.

"Well, there it is - and it does that at the same time every single night. It's truly incredible, isn't it?"

"Incredible, sure, but how the hell does it work? What even is it? Do you even know?"

The look of disgust she gave me for asking that would haunt me for a good while.
