The SCP fandom is a fandom that focuses on the SCP Foundation, a foundation that secures, contains, and protects various unnatural or strange objects, and organisms that could pose to be a threat to humanity if left to roam the outside. These objects and organisms are each given a number (for instance SCP-173). The fandom was started after the release of the free survival horror game "SCP Containment Breach." The fandom has a main hub which is the SCP Foundation Website/Wiki/Forum. You should check it out if your interested.
