Item #: SCP-5157
Object Class: Keter
Special Containment Procedures: SCP-5157 is to be kept in a 10 cm thick Containment Chamber, 20m x 20m in size. Containment Chamber must be made out of pure platinum to minimalise the possibility of SCP-5157 to breach. If a breach is imminent, it's containment is to be put at upmost priority. Research is prohibited otherwise granted special permission from the O5 command. If research is being scheduled, important measures must be taken. Research is strictily restricted to 1 D-Class, provided with any aid of knowledge. Once D-Class has entered the Containment Chamber, the door must be sealed immediately, no light is allowed in SCP-5157's Chamber. If any of the conditions are broken, the O5 command have to be informed immediately, and put every SCP Site on notice for a possible XK end-of-the-world scenario. The current test subject that is communicating with SCP-5157 is then identified as SCP-5157-1 until their imminent death. If due to any circumstance, SCP-5157 breaches then a full site lockdown has to be initiated. All available MTF E-11 ("Nine Tailed Fox") units must be deployed in recontaining SCP-5157.
Description: SCP-5157 is a humanoid entity, one to be a human and one to be a raven. SCP-5157 is only visible after a so called 'ritual of the flight', allowing the user to communicate with SCP-5157. Any other communication is unknown/impossible. SCP-5157 is connected with a raven and a black humanoid, containing the wings of a raven, the head of a raven and containing the texture of a raven, i.e. Feathers. He is said to be clothed in a dark robe, similar to SCP-049. SCP-5157 is an entity, which resided in the 'longing world', which causes The Raven Man to be abscent from his Containment Chamber at most of the time. No known breaches of sort have been caused from his absence from the Containment Chamber. As of the latest research, it has been noted that SCP-5157 kills any humanoid creature from the inside in a matter of seconds. It is unknown how as there appears to be no external damage See Addendum 5157-2-2. There is no known weapon that can damage SCP-5157.
Discovery: SCP-5157 was found in [DATA REDACTED] ██ / ██ / 2020 at approxmiately 2:06 AM, outside the suburban area. SCP-5157 was not visible to the naked eye, which caused major distress and extreme stress to personnel near the entity. Reports of mysterious deaths have been recorded and caused MTF Eta-10 ("See No Evil") to report into the field to retrieve this entity. [DATA REDACTED BY O5 COMMAND]. See Addendum 5157-1-1.

Command: Be advised all units, you are coming up at the LZ, stick together and under no circumstances split up, or decide to 'look' for this entity, understood? We already lost great men to this creature. May they rest in peace.
[Quiet praying can be heard from the aircraft from all units]
MTF E-11 Commander: Copy Command. Who came up with the Containment procedure? Over.
Command: Dr. ███, and considering this creature is invisible to the naked eye, we have to try anything. Please proceed with equipment check.
MTF E-11 Commander: Copy that, proceeding with equipment check. All right everybody, commence equipment check. [Voice becomes masked by shuffeling of equipment]. Uh, Command? What is the need for heartbeat sensors? Don't you think it's too much? Over.
Command: No. Since the entity is not visible and we don't know any way to defend ourselves from it, the least we can do is be notified when one of your units becomes massacred by this creature. Over.

Incident 5157-2-1: SCP-5157 has breached containment, taking the lives of 50 on-site personnel before finally being contained by reinforcements of MTF E-11 ("Nine Tailed Fox"). ██ / ██ / 2020, 03:59:00.

D5836: Yeah, yeah I get ya. So what is this then? Some kind of alien?
Dr.███: You don't need to worry about that. Do you see household items in front of you?

Dr.███: Correct, please proceed with the instructions displayed on the piece of paper.
D5836: What is this, am I doing some childish summoning ritual? You guys really have nothing better to do.
Dr.███: Proceed with the instructions, you will be brought back to the D-Block if you do not co-operate, or even worse.
D5836: Alright, alright fine. I better get something good from this. [Shuffeling of the paper can be heard while also the strike of a match stick against the box]. So what now? I did what the paper said. [A brief moment of silence is broken between them] Oh God… What the FUCK IS TH- [The grunt of D5836 can be heard, as well as his body hitting the floor]
Dr.███: That was unexpected… Alright, we have to get the D-Class out of the Containment Chamber. [The Containment Chamber door can be heard opening, revealing a quiet but menacing grin]. Wait…Oh fuck! [The button for the door can be heard pressed multiple times] Come on! Close you piece of shit! It won't cl- [The screams of Dr.███ Can be heard echoing through the room]
[Alarms initiate throughout the facility, causing massive distress and screaming and shouting throughout the entire facility.]

Closing Statement: SCP-5157 has breached containment and caused a 10 hour site lockdown with the threat of Alpha Warheads to be launched. SCP-5157 has been re-contained and put on higher security, allowing less research from Senior Researchers.
Addendum 5157-2-2: Research was postponed until further notice after the first testing procedure.
Interviewed: Dr. ███
Interviewer: O5-██
Foreword: Research concluded, new information has been defined and a meeting with the leading researcher for SCP-5157, Dr. ███ and the O5 Representative, O5-██.
<Begin Log, 18:02:10>
O5-██: You better have something important to tell me, I don't have time to spare for nuisance. So, what is it?
Dr.███: [Moment of silence is displayed before rattling of paper] Uh, it's about SCP-5157, there was a significant discovery during research. [Pictures of a deceased D-Class after an autopsy, revealing [REDACTED] but no external damage] He can kill anybody from the inside out.
O5-██: You're suggesting he is a volatile entity that can kill you with a single touch? Internal meltdown?Dr.███: Um, yes sir. It was revealed that the D-Class had no physical damage done to his body, however he was [REDACTED] from the inside.
O5-██: So, what are you suggesting we do in this matter?Dr.███: I suggest we keep in containment with restricted permission and higher security and for the time being, keep it as Object Class Keter until we find out how to prevent the damage he causes to Humans, or any matter in that case.
O5-██: I'll discuss this with the O5 command, your work is highly appreciated and will not go unnoticed, we will be in contact with the Site Director of Site-██ to discuss matters. Thank you.
Chairs are moved and O5-██ leaves the room, concluding the meeting.
