 SCP-825 is a standard-sized helmet of medieval design. The degree of wear is consistent with this dating, provided SCP-825 has been well cared for. Efforts are still in place to track down anyone else involved in the incident. SCP-825 has the property of inducing visions in any who wear it. Testing indicates that SCP-825 does not need to be worn on the head, but that insertion of any part of the body within the volume enclosed by the helmet will count as application. Upon application, the subject will be unable to move any part of their body below the neck until SCP-825 is removed. During application, the subject will be unable to see, feel, or otherwise sense their surroundings. With the exception of sounds, which the subject will hear is muted and distant.
