The SCP Foundation is an interesting concept for a website. It’s a place for creative writing that allows for people to create “SCPs”, or things/creatures/phenomena that require special containment procedures. The SCPs, therefore, are all fictional, but each entry is written as if the thing is real.
From the site:
“We are the last bastion of security in a world where natural laws rapidly break down. We are here to protect humanity from the things that go bump in the night, from people who wield power beyond mortal understanding. We are here to make the world a safer place. We are the holders of wonders, and the caretakers of dreams. We are why the world continues.”
Here are some good examples:
Give it a read; some of the entries are really interesting. But don’t read it alone at night, ‘cause some of the entries are also really disturbing.
