SCP-XXXX, alias The Possessive Widow's Ring
Item #: SCP-XXXX
Object Class: Safe Euclid
Special Containment Procedures: SCP-XXXX is to ne kept within a 3 meters radius of Dr. Antonio Silva at all times, to ensure the docile/dormant state of SCP-XXXX-B. If not in Dr. Silva's presence, the entity is to be kept in a heavy containment chamber at Site-██. After the XXXX-1 incident (see addendum below), interrogations to XXXX are to be done in a closed room with 2 security clearance level 3 guards at least.
Description: SCP-XXXX is a seemingly normal ring belonging to the Senior Researcher Antonio Miguel Silva made out of [DATA EXPUNGED] and has a red stone on its top. The stone's nature is at this point unknown, despite the long researches on it. The ring is decorated with dragon-like gravures, the red stone is sustained by a claw-shaped space. The ring itself didn't shown up to date any abnormalities, except for having a ability to perfectly suit the entity's current user's finger, but it's not the most important ability it has. In fact, when SCP-XXXX is worn by any humanoid creature or object, it takes over the subject's body and acts as the consciousness contained inside the ring itself. This consciousness, labeled as SCP-XXXX-B, is a seemingly feminine person. It claims to be Senior Researcher Silva's deceased wife. Dr. Silva [REDACTED] the entity's story. XXXX-B seems to own a extremely large knowledge about in microbiology and virulogy, such knowledge that the entity is often asked to share all their knowledge, but the entity refuses for an unknown reason. XXXX-B seems to keep a extremely docile, almost dormant state when in Senior Researcher Silva's presence, that it claims as "a calming and pleasant presence", and is more eager to talk and answer to the interrogatories that it passes through regularly. When not in a 3-meters radius from Dr. Silva's presence, the object is completely different. People said that it is "rude and provocative in tone" and that it "often insults or denigrates" people in their presence. It is important to note that XXXX-B only accepts Dr. Silva, feminine, black heared D-Class personnel, or a 189 centimeters tall and 85 kilograms weight wooden dool as host, rejecting anything else.
Addendum: XXXX-1 Incident - ██/██/████
Subject: SCP-XXXX-B
Incident: SCP-XXXX-B, during a routine interrogatory, started to become agitated and paranoiac after Dr. Silva's leave because of [REDACTED], stating that "You'll hurt him, you'll kill him", logically talking about Senior Researcher Silva. It then started to be aggressive towards the staff members that came to reassure her. It eventually causes a 3-days long containment breach.
Procedure: A 10-man MTF unit was dispatched to recontain SCP-XXXX-B and after three days the entity was found in [DATA EXPUNGED] and recontained at Site-██.
Results: Recontainment successful. Casualties : 3 badly harmed MTF units, no deaths to declare. Object's classification changed from "Safe" to "Euclid".
Analysis: This containment breach shown that XXXX-B possesses incredible strength, as it almost terminated 3 highly-trained MTF units armed with 9mm rifles.
