First point, this RP takes place 100 years after the battle, guilds don't exist in that time period, meaning he could never have paid a visit to the remnants of Fairy Tail. The second thing comes directly from your sheet.

This is literally impossible to do in this RPs timeline.
I did read the OP and I now see your point.
Hmmm....
Traveling to Magnolia is possible or I imagine it'd not be mentioned in the "settlements" hider. Studying his tome is possible. I see your point about the remnants thing though. That's a very easily changed portion of the CS and doesn't influence anything in regards to how he ends up as a person.
I just figured "Well Fairy Tail was instrumental in saving everyone else (that wasn't involved in the battle) from Zeref and the Slayers' rule/destruction. I'd figure that there was some kind of memorial to honor that even if magic is hated because of the destruction and death it wrought" However, apparently I was wrong, and for that I apologize. I'll put it on my list of things to edit :)
Thank you for catching that by the way. I didn't think of that.
