Item #: SCP-XXXX
Object Class: Euclid
Special Classification Procedures: Public circulation of SCP-XXXX instances are to be strictly monitored by MTF Alpha-4 ('Pony Express') operatives at all times.
As there is currently no feasible way the Foundation has uncovered that will prevent the spread of SCP-XXXX and SCP-XXXX-1 without unintended consequences (Refer to Addendum XXXX-A), all of SCP-XXXX-1's processes are to be seen through to its conclusion. All tests related to SCP-XXXX are also suspended at this period of time.
In the instance that a member of the public receives one instance of SCP-XXXX, the use of Class-R amnestics are permitted and are to be administered on any member in the public who has a close relationship with said affected member. For the rest of the public, the 'Untimely Death' cover story is to be used to refer to the affected member in future references and conversations.
Description: SCP-XXXX is a sealed standard blank paper envelope without a postage stamp and with the word 'Congratulations!' written in red on the front found appearing inside mailboxes across various neighborhoods in Florida, Maine, and West Virginia in the United States of America at random periods of time.
SCP-XXXX contains SCP-XXXX-1, a polished copper coin free of any engravings or markings, and a handwritten note addressed to the owner of the mailbox that SCP-XXXX has appeared in. The standard format of the handwritten note is as noted:
Congratulations, XXXXX!
Based on extensive research we have conducted on your lifestyle, we have concluded that your lifespan is dangerously low and that you have a high risk of dying.
HOWEVER, DO NOT PANIC!
Enclosed in this envelope is a special coin that you can use to make your journey to the other world easier. Just follow these simple steps below to learn how!
- On the day after you open this letter and read this note, head over to the bank of your nearest lake. Any lake will do!
- At exactly midnight, place the coin on your tongue and say the following words: 'Dear Charon, please grant me passage to the other world.'
That's it! We will take it from there, so you do not have to worry about what happens next!
We hope you have fun spending the coin!
Disclaimer: If you do not follow the steps above, be warned. You will suffer a horrible fate.
Should the person receiving SCP-XXXX accurately follow the steps indicated on the note and be present at the lake at exactly midnight, a small wooden boat with a hooded figure (hereby designated as SCP-XXXX-2) will materialise and begin rowing towards the person until it reaches the bank. Once SCP-XXXX-2 reaches the bank, the hooded figure will grab the person's arm and lead them onto the boat, which will then sail off towards the centre of the lake. Subsequently, SCP-XXXX-2 will dematerialise, and the person will float back towards the bank of the lake without any sign of life. Any attempts to revive the lifeless bodies have been unsuccessful, but scientists have noted that they seemingly have expressions of intense joy on their faces when they are retrieved from the lake.
In contrast, should the person receiving SCP-XXXX refuse to open it, ignore the steps indicated on the note or make a mistake in following the steps, they will subsequently dematerialise from sight and materialise approximately three days later, similarly without any sign of life, but noted to have expressions of pure terror on their faces. When they are recovered, SCP-XXXX-1 will be found lodged in their windpipe, with no indication as to how it was done.
The people chosen by SCP-XXXX are random and do not follow a clear pattern of age, lifestyle or history of past illnesses. Any attempts to trace the manufacturer of SCP-XXXX-1 or to interact with SCP-XXXX-2 have been unsuccessful.
Addendum XXXX-A: SCP-XXXX Testing Logs
Testing Log XXXX-1
Conducting Researcher: Dr. Reese Martens
Subject: Jordan Neumann
Test: Operatives immediately pulled the subject away from SCP-XXXX-2 once he had stepped onto the boat and transferred him to a nearby site for observation.
Results: Over the next few days, the subject's health deteriorated rapidly. Presiding examiners have reported that the subject appeared to be aging at an abnormal rate, and that he was constantly screaming and attacking the nearby staff that attended to him before dying five days later. All operatives involved in the test subsequently died under similar conditions.
Testing Log XXXX-2
Conducting Researcher: Dr. Reese Martens
Subject: Elizabeth Halloway
Test: SCP-XXXX-1 was taken away from the subject and secured in a vault in Site-14, where it was kept under close observation.
Results: The subject dematerialised, and was subsequently found dead with another SCP-XXXX-1 lodged in her windpipe. The original SCP-XXXX-1 later vanished when Site-14 exploded, killing 37 researchers. The relationship between its disappearance and the Site-14 explosion is currently being investigated.
Testing Log XXXX-3
Conducting Researcher: Dr. Reese Martens
Subject: Michael Williamson
Test: The subject was peacefully terminated using [DATA EXPUNGED] a few hours after he received SCP-XXXX.
Results: After the subject's death and subsequent transfer to the morgue for observation, SCP-XXXX-2 materialised a few hours later and retrieved SCP-XXXX-1 before dematerialising.
