SCP-5782 The Lord Of Pain
Object Class: Apollyon
Containment Procedures: Impossible, do not attempt containment.
Description: SCP-5782 refers to to 2 anomalous objects. SCP-5782-1 is a a set of ruins on the north pole of mars, thought to originate from future humans, uncovered by SCPS Conquistador. SCP-5782-2 Is a serpent-like creature that is made up of metal and blades, which attacks intelligent life indiscriminately and randomly, originating from SCP-5782-1.
SCP-5782-1 has not been uncovered entirely and is considered to stretch across the underground of the planet. The ruins, or the 'Tombs of the Pain Lord' as referred to by a religious occult based around SCP-5782, have an unexplained effect of time dilation within 3km of the site, and it is advised that no personnel attempt to enter within a 2km radius from the site in case of a time surge. The site seems to be moving backwards in time from the point of construction, as new objects appear sporadically within and around the site.
SCP-5782-2 had its first sighting shortly after discovery of SCP-5782-1, as a silhouette behind a canvas wall, when security reached this area they found it covered in blood and the man inhabiting the space gone, presumed dead. These occurences frequented more over time and a religion was formed by those who had seen SCP-5782-2 called 'The Church Of The Worship Of The Pain lord', being described as above. Attacks then spread from mars to Earth, where the Church grew as more witnessed the killings, multiple disinformation campaigns started, all failed.
The Chaos Insurgency sent a mission to mars on 03/04/2041 wherein they raided the Mars research centre at SCP-5782-1 and eliminated all staff present and researched the anomaly. SCPS Galleon was then sent to recapture the base and learn what the Chaos Insurgency group learnt of, however the group fleed and hid in a cave in Valles Marineris, where they supposedly developed the technology to open SCP-5782-1 and release SCP-5782-2 on a greater scale, however they destroyed the technology and were killed by SCP-5782-2.
It is estimated that 1/5 people who die are killed by SCP-5782, this estimate has increased in the last 5 years, suggesting that within 100 years all intelligent life on Earth will be killed by SCP-5782, and within 200 years human life will be extinct.
Addendum 5782-1 A > 06/24/2035 "We had a successful landing today, and will head up North to observe the polar ice caps, position N: 72 degrees, W: 240 degrees. A strange structure has been observed NNW, will investigate in due time. some of the men have been experiencing strange headaches and confused sense of time, we think it may be due to the lack of a magnetic field and a low-G environment. however this is unconfirmed."
06/25/2035 "We visited the structure today, and found the cause of the men's headaches, an set of ruins shaped like those found in the valley of kings, but with a strange ability to speed up and slow down time. Possible Alien life? Anyhow, amazing discovery and will interest the foundation."
06/26/2035 "What the fuck was that thing? It just appeared, killed Alex and left. It looked like a snake from the silhouette. Some men have been experiencing hallucinations of this 'Lord of Pain' and have started worshipping the thing, but they're crazy to. It killed Alex fucking Becker, our MTF squad commander, if it killed him, it could kill all of us."
08/12/2035 "retreated to SCP-4782-1, it wont get us in here, must have been at least a year in here."
