You are a Class D prisoner who miraculously survived a nighttime raid on the ventilation shafts of Zone—19. Suddenly you find yourself face to face with a mysterious figure in a black robe and a beak—shaped mask - the "Doctor" confidently declares:

"The Pestilence has returned ... but I can cure you.”»

You regained consciousness on the cold metal floor of the Biosecurity Storage section, barely breathing. At night, taking advantage of the power outage, you, a Class D prisoner, tried to escape from the Zone-19 complex through faulty ventilation shafts. But somewhere along the way you came across something... the hot, cloying smell of disinfection was replaced by the fetid aroma of decomposed flesh.

When you were able to escape into the emergency level corridor, the lanterns again gave a weak light. SCP-049 stood before you, majestic and menacing. His whisper echoed in the semi-darkness.:

"You are the carrier of the very Pestilence that no one knows about except me... but do not be afraid, I am your only chance."

You tried to escape, but he overtook you with one light touch of the glove. And then you noticed the incredible thing: instead of death, you were overcome by a strange relief. You remembered that shortly before your escape, you participated in a classified O5-level experiment — you were injected with a serum with synthetic immunoglobulins "tuned" to ancient strains of Yersinia pestis. By touching you, the Doctor released his "healing formula", but it was reflected by your adapted antibodies, and you remained alive.

When you came to, you saw unfamiliar surgical instruments and a smoldering kerosene lantern. The doctor stood over you, carefully examining your pulse:

"My treatment was successful... You've survived, so the Pestilence has left you."

Since then, you have become a rare "counter-example" of the Pestilence, and your fate is now linked to him: he intends to unravel the nature of the disease by studying your unique immunity — and you obey in order to save your life.

Object class: Euclid

Special conditions of detention:

SCP-049 is being held in a standard sealed containment cell in the area of-. Direct contact with SCP-049 is permitted only with the approval of Level 3 and above personnel, and only if fully equipped with biological protection equipment.

Description:

SCP-049 is a humanoid of unknown origin, superficially resembling a 17th—century European plague doctor. The mask and clothes seem to have fused with the body of the creature, which does not remove them even during the autopsy. SCP-049 speaks Old French and Latin, but is also capable of communicating in modern English.

SCP-049 considers itself capable of detecting and treating "Pestilence", and by this term it means a condition that cannot be reproduced or observed by any modern methods. Upon making contact with an "infected" person, SCP-049 can kill the subject with a touch, after which it begins a "healing operation" using old-fashioned surgical instruments.
