I like your story, but I am confused, if Harry is Jericho, and he was raised by the Templar, then where does the wizarding world think Harry is now? Does Harry know who he is?
If you're confused then it means I achieved my goal. Im purposly keeping Harry's past a secret and only unveilling bits and pieces. I will say that the wizarding world has mixed views on the missing Harry Potter, some think he is dead others think he is missing. All they know for certain is that Voldemort dissapeared that night and Harry Potter was no where to be found.
Chapter 4 will show Harry having a sense of familiarity with some characters and in Chapter 5 a little more about his past will be revealed.
