Hello, Everyone!
Right, for a long time now I've had the question floating around in my mind about how things might change if a Muggle were involved in the Harry Potter series. The basic thought going through my head was "What if a trained soldier were to be present at Hogwarts through Harry's school years?" From that question came this story.
Wherever possible, I'm sticking to what was originally in the books as how they'd be affected by a muggle. Some actions taken by characters other than Harry have my own interpretation of why they acted the way they did, but that's simply because we don't know why they did what they did. Hopefully it will all make sense.
To explain about the timeline- a nice thing about Harry Potter is that you could theoretically place it at any point after World War II and have it work out fine. I'm using modern designations for firearms and such, but since almost all other technology doesn't work at Hogwarts, the exact dates don't really matter much. For convenience sake, it might be best to assume it takes place in the modern day.
If it's in the Harry Potter books (1-7), it's canon for this story. Information from Pottermore or The Wizarding World websites will only be considered canon if I specifically reference them in the text.
