The SCP Foundation is a wiki-based creative writing website. Genres are primarily horror, science fiction, and urban fantasy, usually written in the format of a scientific report although more traditional methods of storytelling are occasionally employed.
Expect mildly gruesome/shocking content.
A favourite of mine, in fact, I still love it! Not for children most of it, shocking images and pseudo realistic writing. The SCP Foundation is real of course, but hidden in another website, this one is for entertainment. ;)
