Changeling

Whatever you're doing, stop.

Whatever you're thinking, stop.

We don't have a lot of time, so, listen.

First of all, don't trust anyone around you. They're all changelings. I don't know what kind of life you've been living, but it's about to change. It's hard to explain. I'll give you more information once we're out of immediate danger but for now, just trust me and run.

There's no one around, right? Okay, good. Now, I'll tell you what's going on.

About three years ago, we found something weird. Well, more like accidentally made something weird. It was during the later stages of testing a new sort of tool, one that WellTech has been developing for some time. I was one of the main researchers, so I got to see the whole thing up close. Long story short, we were messing around with stuff we thought we understood. Looking back, it seems like there was some dark matter in what we were working with - an incredibly tiny amount, mind you - and that must have been what screwed with our calculations and experiments. One second, everyone was observing the experiment as usual, then, half the people around me were... somehow broken. Some of them were dead, lying on the ground in pools of smoking, black blood, some were missing eyes, twitching sporadically, and some were just gone. But I - thanks be - was okay, albeit shaken up.

Since then, I've learned a lot. It seems that whatever the problem is, it's not spreading like a sickness. I've observed apparently random pockets of this phenomenon all around the world, some areas more affected than others. Some people, like me, are, to all appearances, unaffected. Unfortunately, all of them have died since.

You're my most recent find.

As for the whole changeling thing, it's just one more effect I've observed. The family and friends of the unaffected often seem unaffected themselves, but there's a giveaway sign that you'll notice if you listen for it.

I- I can't stay any longer. I'll be back, I promise. Please, stay safe until then. Don't let the liars fool you.
