It was inevitable. In a world full of monsters and cosmic horrors and all sorts of weird things, it was bound to happen. The end of the world. Some of the SCPs were designed to do it anyways.
But it wasn't ever supposed to happen like this. Doctor Parker sat in his office, pondering what was happening. A week ago, it had all been fine. Many had left in the previous years, but containment had been maintained, and the world was, for the time being, safe. Life wasn't normal, but it went on.
And then came the start of last week. A huge drop-off of Foundation personnel, while often mourned, was never considered odd. This group, though, had vanished out of existence. Many could remember them, but records of their deeds and history were simply gone. Task forces were assembled, naturally, but to no avail.
The next day brought worse news. SCPs started disappearing. At first, it was the small ones, ones that had been locked up in the back of everyone's memories, like SCP-132. But then the more important ones began vanishing. Everyone swore they could remember SCP-082, but it wasn't in its cell. Its cell didn't even exist any more. The day 173 vanished was the worst. It had started the Foundation. With its disappearance, many lost hope.
Two days after it all started, the task forces figured out something of a pattern. Many researchers and doctors were vanishing after all of the SCPs and Foundation history they had archived went. Not much to go on, but it gave those remaining an impression that there was some order to the senselessness around them. Though it didn't help matters, as those who made the discovery vanished soon afterwards.
The world began to die. Whatever was eating away at the Foundation wasn't satisfied; it wanted to devour the whole world, and it was. Within a day, most everything was gone. At that point, it was only a group of less than a dozen, hidden away at Site 19 with the last SCPs. They had built up a field designed to combat entropy. A relic of a genius mind who had long ceased to exist.
On the last day, Doctor Parker locked himself up in his office. In the past hours, the men and women around him had vanished, along with all their hard work. Site 19 was being consumed all around him, and only his office remained safe. So he ran in, locked the door, and waited. For what, he didn't know, but he waited nonetheless.
Heaving a sigh, Doctor Parker lifted himself out of his chair, and walked across the room to the mirror hanging on the wall. He was determined to stay alive, but he could feel himself slipping. Having never archived an SCP, he had lost nothing to the decay. But that wasn't true. He had lost friends, he had lost family, he had lost the entirety of the world he lived in.
And now he was losing himself. Bits and pieces of his memory were fading, even though he was only in his late twenties. Even here, with a smaller version of the device protecting him, the last remaining part of the world he knew was vanishing. Anger tried to cloud his thoughts, but there weren't any left.
Turning towards the door, he hoped against hope that opening it would reveal something. The day before he had done so, and found nothing but an infinite whiteness. But maybe he had just been tired. Maybe now, with a clear head, there would be something awaiting him on the other side of the portal.
He opened the door, and he saw madness.
There was something outside his office, but it wasn't anything like he knew. A whole new universe was making itself outside. Even though it was only in its formative stages, Parker could tell right away that it would be done soon, and when it was, it would be nothing like the one he knew. There would be no room for Doctor Parker, or the SCP Foundation, or anything sane and right from the one before.
Doctor Parker stood there for the longest time, letting all of this sink in. He could fight on. He could fight and make his own niche in the new universe. It could try its hardest to reject him, but he could survive, and he could make a living. Hell, he could even rebuild the whole of his universe, with enough time.
Then, he stepped out into the entropy, and let it swallow him.
