Item #: SCP-5131
Object Class: Safe
Special Containment Procedures: SCP-5131 must always be contained in a soundproof room approximately 5x5x5x5 in volume. Absolutely no sound devices must be present inside the containment cell. Monitoring of the room may be permitted to Staff with a level 3 Clearance or higher. A seal over SCP-5131’s mouth must be present at all times.
Description: SCP-5131 is an entity capable of morphing itself into a variety of different characters. The entity itself seems to keep a consistent face of a middle-aged white male with a variety of beard shapes depending on the character. Entity is more than capable of speech and knows every word in the English vocabulary. Absolutely no vocal communication must be performed with SCP-5131. When a subject speaks to SCP-5131, they experience a sleepy feeling, initially. Halfway through a conversation, subject feels lightheaded and is barely able to do basic motor skills, such as walking. The conversation always ends with the subject either falling asleep, getting into a coma, and potentially ███.
Addendum-01: SCP-5131’s conversations show no malicious intent towards class D test subjects. The entity always has a common goal regardless of the character it morphs into: to “relax” the person in front of it. There hasn’t been a session where the class D personnel haven’t experienced ████████, or been led into ██████.
Addendum-02: It has been reported that the longer the session lasts, the higher the likelihood of the test subject being in danger. The longest conversation that has ever been recorded (without sound) lasted for one (1) hour six (6) minutes and six (6) seconds, during which that time SCP-5131 had morphed into ██████.
Addendum-03: SCP-5131 once transformed into a similar SCP known as SCP-049, otherwise known as the Plague Doctor. The two SCP’s were put into a room and were allowed to talk. The recording required ten (10) different people listening to the conversation due to the sleepiness effect. It must be noted that the effect is only present in human organisms. Here is the audio transcript of the session:
049: I see you’re a medical man such as myself.
5131: Indeed I am. My name is Corvus Clemmons, I exercise my work in the █████. Have you heard of it?
049: An asylum worker, I would expect no less from a medical man. Have you had any luck with the Great Pestilence?
5131: Unfortunately the process has been slow, but I could work with you in the future, should these fellow doctors who are listening to us allow us.
049: How long have you been looking for a cure?
5131: I have lost count of the centuries that have gone by. I can ask the █████ to allow you to join the ██████, my relative Professor Clemmons would appreciate another doctor.
After SCP-5131 finishes its sentence, both entities begin speaking in an unknown language. Attempts of deciphering the language have proven futile. More monitoring is required for a complete file. Research of the so called ██████ who is suggested to be the creator of the █████ has been started.
