Do some research

It still strikes you as odd that the app deleted itself after you downloaded. Someone else must have used this app before and had a similar experience to yours. You decide to look into it some more after your lunch with your friends.

Returning home, you begin doing research on this "Mal0" creature. Interestingly, there are some scattered stories in blogs and threads around the internet, but most of these are on forums and message boards about crazy conspiracy theories. Nothing seems to be credible enough to help you figure out what's going on.

As you begin to lose hope, your phone goes off in your pocket. Part of you hopes that Dennis or Larry had something to say, but you know deep down that it's Mal0 again. Sure enough, the creature is sitting outside your window in the picture. The image shows her winking at the camera as you sit in the background scrolling through conspiracy websites. You're about to put your phone away when a message at the bottom catches your eye.

<Aw! Trying to learn more about little old me? I'm flattered! Try this one out for size, John>

Mal0 was helpful enough to supply a website title in the photo. For a moment, you're genuinely grateful to her for doing so. Maybe she isn't so bad after all. You quickly shake the thought from your head and search the website she gave you.

Incredibly, the website appears to be a database logging all kinds of strange creatures, alien visitors, eldritch deities, and strange phenomena. Mal0 is just one of the creatures described, but your curiosity gets the better of you as you begin looking at the other entries. All of them are listed as SCP's.

One shows a thin, yet muscled man wearing nothing but a plague doctor's mask. He apparently walked around nude but for the mask and talking about how he meant to cure a "pestilence." When he acquired a target, usually a woman, his touch would disintegrate all of her clothing before seducing her into sex. The women claimed to only be embarrassed for a short moment before falling in love with the doctor, called 049. How many women he had done this to was not listed.

Another entry shows something called the "Shy Girl" or 096. The creature is a tall, grey woman who refused to wear clothes, similar to Mal0, but always prefers to keep her face covered. Whenever someone sees her face, she becomes gripped by uncontrollable lust and races to find her viewer, who she'll strip naked and have her way with. Her lovers have called her indescribably beautiful, even though she obviously doesn't think so. How she senses and finds her viewer is unknown.

Another describes an odd lake where single people, men and women, claimed to go swimming after seeing their dream lover in the water. After doing so, they appear on the shore with said lover, but with all their clothes gone. Not much else is known, except that the article keeps repeating, "You do not recognize the skinny dippers in the water."

Now, more questions eat at you than before. What is this SCP Foundation? How many of these beings are there? And how does Mal0 factor into this?
