First thread, so let me know if there's an SCP like this already.
The idea is that this book was found in data expunged library. It's a self help book titled "Changing Yourself" with seemingly innocuous steps, like listening to your idol's music, make your room look like theirs, data expunged, data expunged, yada yada yada.
As you go through the steps, the person following the steps starts to actually think that they are the person they chose to model their stuff after. People don't usually do all the steps, because they're either too hard or can't feasibly be done, like read through their journal. So they stop after becoming somewhat like the person. However, were a person to follow each step exactly, in order somehow, they would actually believe they are that person.
It was discovered after the city of data expunged had an unusually high rate of producing successful people.
The foundation now has it, and has the means to replicate just about any person of significance if it comes to it, like 05 personnel, the president.
I like this idea, let me know what yall think, so that I can go on with it. In the right hands, I feel that this could be a THAUMIEL class object, but in mine, it would probably be better off as SAFE.
