Corrupted

The Virus

People are rushing to get to bunkers and hidden places around the world. The sky is nearly pitch black, with a slight purple tint to it. Creatures are beginning to form around the planet, bringing chaos everywhere they go. It's pouring heavily. I am Baryll Goint, and this is my recollection of the events that occurred around 1983, April 23rd, and beyond.
It all started on April 19th, when someone told the world governments to prepare for the 23rd, as there would be an apocalypse starting on that day. Nobody believed him. He disappeared later that day, last seen heading into the forest with a friend, whose body was later found with their mouth forced into an inhumanly large smile, hung from a tree, with a nail through their left eye. Nothing else of interest happened until the 22nd when several married couples with kids came home to find at least one of their children stabbed to death with a spear and pinned to the ceiling with a nail. A dark figure was also seen in the act of impaling a toddler with a spear due to the toddler crying, causing the parent to come into the room, only to see the figure stabbing the toddler through the heart. The figure dropped the toddler's body and jumped through the window. The parent managed to get a picture and a recording of the figure before it disappeared. The next day, there were several reports of the previously mentioned dark figure stabbing people in public, and the sky started to get darker. More of them appeared and attacked people. Everybody rushed to get to safety, but nobody was truly safe. Few survived the event. People died in the bunkers, but out in the wild, nobody died. Only a few days later, several people were found dead in a star pattern, with their faces torn off and placed in the middle. There was a single lit torch next to the bodies. All of the figures disappeared, except for one. The last one spoke a single sentence. "Oh, dearest Lord, may you please accept this sacrifice of our distant cousins in flesh and bone..?" Before tossing the torch into the middle of the pile and stepping into the flames, burning away with the flesh of the bodies. Everything else went back to normal, for the most part. Several other figures have appeared over the last 20 years, 6 of them to be exact.
The year is 2003. Now, I'm searching for answers to all of my questions. I've found only one answer-- Where these things came from. They came from a different place in time and space, millions of years in the future, on a mysterious planet. I'm looking to find out why they came next, so I've been searching for places that seem a bit off. I've found a few, but I've only seen burnt and melted objects laid out in shapes, such as a star. I have seen 2 of the dark figures recently, but neither of them saw me. Today, I'm entering a cave where the locals claim to have heard "unholy" sounds coming from within, with none of them having entered out of fear. I've got my gear, and I'm going in.
I've been searching for a few hours. My torch is beginning to go out. I feel unsafe. There's a presence nearby and a sort of "static-y" feeling in the air. I hear sounds coming from a hall from which I also see a faint deep purple glow, similar to the red glow of the dark entities. Some of the sounds seem similar to those described by the locals, while others sound more like solid crystals, almost as if the crystals are singing. I set a recording camera on the ground and hide behind a wall. Something passes by, recorded by the camera. I slowly pick up the camera and look at the recording. It's a bit too graphic for me to describe here in absolute detail. It's like one of the dark figures, but more... Unnatural. Rusty pipes, moss, leaves, gears, and more, all within this... Crystallized, glowing figure. Its unnatural speed and the sounds it makes lead me to believe it was some sort of "hyper" version of the dark figures, which ended up failing and was cast into the depths of this cave system. I leave the cave before it can see or hear me.
I ended up heading to the hideout of one of the survivors of "The Darkening," which is what I call the thing that happened in 1983. They weren't there, and the place looked abandoned. I walked around, finding some interesting things. I found a mirror and looked into it. The reflection showed some darker things in the room, such as a hanging body behind me, which wasn't physically there. I walked away from the mirror and continued exploring, when I found a small chest with several locks, as well as a note telling me not to open it, no matter what. I picked the locks and opened them, only to find a small, dark red/purple, glowing rock-like thing. Everything about this place felt off. When I turned to go back... The body was there, just as it was in the mirror. I destroyed the mirror, shut the chest, and left as fast as I could, not realizing that the rock-like object was
