The SCP Foundation

Here's a bit of randomness for you...

SCP artifacts pose a significant threat to global security. Various agencies from around the world operate to maintain human independence from extra-terrestrial, extra-dimensional, and extra-universal threat. In the past humankind has been at the whim of these bizarre artifacts and similar phenomena, but we have now reached a point in history where we can begin to control and contain these defiances of natural law.

You are now working for the SCP Foundation. You have no need to understand how or why we operate. What you do need to understand is how vital your mission is.

In short, this is a bit of science fiction combined with a bit of roleplaying and a lot of "wiki" methodology. People write descriptions of paranormal objects/creatures/phenomena, using a work-in-progress style guide that helps make the fiction more believable, but far less readable.

Here's the best ... "article" I've found on the site so far:

SCP-033 was discovered by alert SCP field staff on a discarded, irregularly-torn napkin in the ████████'s ████ pub in the university town of ██████ on November ██, 19██. SCP-033 appears as a field of complex mathematical symbols ranging from simple layman-identifiable representations to those only interpretable by highly-trained mathematicians. The "sum" of the symbols is equal to a previously unknown integer (designated Theta Prime by Prof. █████████) of intermediate value between █ and █.

Prof. █████████ : Every school child knows that 2 plus 2 is 4. The solid mathematical certainty of numerical order and value is the basis for all logic-based systems. We know that after 2 comes 3 and after 3 comes 4. What this formula proves is that we missed a number somewhere. Imagine if all our technology was based on the belief that after 4 came 6. We simply didn't know or conceive of 5. That is in essence what this formula proves. We missed a number.

I recommend against visiting the website if you can avoid it. If it's not the sort of thing that interests you, you'll be confused and/or bored by what you find. If it's the kind of thing that you might enjoy reading, you run the risk of spending hours at a time peering through the dross to find the gold. (But if you find something you like, please come back and post a link!)
