The fountain of youth,
Level classification: Euclid
Containment Procedures: SCP… is contained in a 15m by 15m by 15m isolated metallic box in site … with the nearest facility buildings located about 120 meters away. The room requires no Maintenace and has constant camera surveillance, there are three high-security fences positioned different distances away from SCP …
Description: SCP … is a roman fountain, dating back to around 100AD just after the end of the Roman conquest.
The fountain is made up of three stone basins with the largest having a circumference of 35m, The fountain is structured like a cone, with the largest located at the base and the and the smallest at the top.
On the sides of all the basins, there are several carved in runes with seemingly Latin origins, though does not match any language known today. There are several Christian imageries like Mother Mary, crosses and Hebrew lettering claiming "The fountain of youth". SCP … contains an unknown liquid with a translucent, yet viscous consistency in with a metallic shimmer. The fountain consistently trickles the liquid from the top with unknown processes.
SCP… is normally harmless if kept clear of any humans in a 100-meter radius. But once a subject enters, they receive a great urge to venture towards SCP …, once they reached the fountain they become notably more urgent and violent racing towards the fountain. If the subject is very young they don't get affected by the pull and older people have a lesser effect, with SCP… really effecting young adults and adults who demand the best of themselves. If the subject comes in contact with the liquid nothing seems to happen, until they leave.
From now on the subjects seemingly doesn't age, with only the growth of body hair that continue. They also claim 'that they have been rejuvenated,' the subject becomes extremely athletic, knowledgable and remarkably high functioning, almost being superhuman, becoming comparable to an athlete, as smart as a physicist and the brain function compared to the character sherlock holmes. Any scars or wounds the subject had would heal and if the subject had any missing body parts, it would seemingly grow back, only leaving a slimy residue.
However, once every year on the exact time of the subjects birthday the subjects claim an "extreme pain" which then leads to the deformation of the body, joints begin to bend and punchers the skin the body contorts, stretches and rips, throughout the process, the subject is screaming and in pain, their now unrecognisable body becomes a pile of bloody, pulp.
After an hour the pile begins to reform pulling itself together muscle by muscle, bone by bone until they fully reform to their former self still having the abilities the fountain gave them.
The subjects claim it's an indescribable pain throughout the entire experience, they could feel everything, even being able to feel, see and touch when they were in their dismantled state. Most of the subjects killed themselves in less than 3 years after the interaction with SCP … stating "The pain was too much".
