Some SCP Ideas I had:
1. The Loyalist's Brand: An ancient iron brand that marks the subject with the latin phrase "unus ex multis" or "one of many." The subjects who recieve the brand lose their original personality and refer to themselves as servants to an unknown Master figure. They will frequently attempt to breach containment and try to steal the brand before trying to flee the site/area/place of containment for parts unkown.
2. Timeslip Portraits: A collection of 6 paintings from different time periods in American History each depicting different figures. Anomalous effects only occur in the house where the portraits are found. Subjects viewing a portrait will suffer a seizure followed by catatonia. While comatose subjects wil mentally regress to the time in which the portrait depicts. Subject will be able to interact with others in this state, but will be unable to damage the portrait.
