SCP

This is considered part of Creepypasta. It's different and interesting if you were to think about it.

SCP is a secret of organization of scientists who are devoted to collecting and containing all the supernatural objects and creatures in the world for the sake of protecting the rest of mankind from them. SCP stands for "Special Containment Procedures" and their unofficial motto is "Secure. Contain. Protect". Items contain by the SCP are classed as either Safe, Euclid, or Keter. The foundation often uses declasse personnel to handle experiment extremely harmful objects and anomalies. These people tend to normally be prisoners from violent crimes and those who've been put on death roll. In times of drastic measures the foundation will even use political prisoners, refugee populations, and ordinary civilians.

One of the most disturbing things about SCP is that all of them are located and contained after coming into contact with a regular civilian human going about their business. With no knowledge of what the thing is, how it works, or where it came from. Considering there's a unknown number of supernatural objects that could qualify as an SCP scattered around the world and you could run into, say, and undocumented "Keter" class at any minute during your daily business.
