Character: scp-1440
SCP-1440, aka, The Old Man From Nowhere. Is an anomalous entity in the SCP Foundation Mythos.
SCP-1440, is a human male of ambiguous ethnicity who appears to be in his 80's. Despite the fact that the Foundation has been aware of his existence for over 50 years, he does not appear to age and is presumably immortal.
SCP-1440's anomalous nature becomes apparent once it comes into contact with human population or man-made objects and remains in contact with them for longer than a three days; Prolonged exposure of any man-made object or person to it will cause increasingly destructive events to occur in SCP-1440's vicinity, until the destruction or death of said human element. The only exceptions to this are SCP-1440 itself and its belongings (its clothes, a sack made of unidentified material, a pack of worn playing cards, and a small glass cup).
Because this also affects the Foundation's Facilities which are man-made, containment of SCP-1440 is completely impossible.
Due to the growing size of human population and its rapid expansion into previously empty areas, it is becoming increasingly difficult for it to avoid contact with humanity while still adhering to its compulsion.
SCP-1440 is based on The Wandering Jew and The Soldier and Death
SCP-1440 is classified as Keter.
