SCP #: 5038
Object Class: Euclid
Special Containment Procedures: SCP-5038A must be contained in a 60x60cm (2x2ft) box at all times. Class-D Personal may be used for testing in Unit-39. Any personal (SCP-5038B) that manage to survive the effects of SCP-5038A must immediately be sedated and transferred to the Medical Section on sub level 2. After which 5038B will be transferred over to the Research Section on sub level 4. If 5038B does not survive they will either be transferred to the Research Section on sub level 4 or to be incinerated on sub level 6. This may change only by the request of clearance level 4 personal or higher. If SCP-5038A is reported missing, contact security immediately.
Description: SCP-5038A also known as "The Crown" causes a wearer to become mad. SCP-5038A will cause 5038B to believe that they are the King/Queen of England, Germany, Russia, etc. and will proceed to terminate any other personal (deemed as SCP-5038C). 5038B will proceed to feast on the remains of 5038C. After feasting, 5038B will search for more personal to consume until they are terminated. Several Tests indicate that 5038A's effects are able to be cured by means of therapeutic sessions over a PA, although this takes several months. Requests to terminate 5038A by survivors have been denied.
