I was going to save all the answers for later chapters, but I can tell that in order for you guys to enjoy the story, you must know the answers to your questions, so...
Here they are :D
IMPORTANT: In this story some things are slightly different to the real books, such as the Death Eaters changing all these rules.
Vernon and Petunia were sitting in Aberforth's living room drinking tea in silence. Aberforth was rocking backwards and forwards in his rocking chair, awkwardly looking around. Vernon was the first to speak;
"So, uh, can we ever go visit the castle?"
"Yes" Aberforth answered. "The Death Eaters have lifted the charm that makes it invisible to muggles"
"Muggles?" Vernon asked.
"Non-magic people" Aberforth answered. Vernon just grunted and took another sip of his tea. Petunia was next to ask a question;
"How was my son allowed to perform magic with Harry Potter's wand? I thought the school had strict laws on that"
"Not anymore. The Death Eaters have changed everything."
"But doesn't 'the wand choose the wizard?'"
"Ah, so I see you have been paying attention... Well, yes it does. But anybody can use a wand (A.N In the Deathly Hallows Harry uses Draco's wand), however their magic will not be as great as it would be if they had their own wand."
"So how will Dudley learn magic then?"
"They have some spare, un-owned wands kept for emergency up in the castle, I'm sure they'll find one to suit your son."
"And what about other school things?" Vernon grunted out.
"As I said before, the school has changed. You really only need your wand, books aren't a priority anymore."
The Dursleys nodded and continued to sip their tea in the returned awkward silence...
Hope this has answered some of your questions! If it hasn't, just assume that it is different in my story. I'm not really a good realistic FanFic writer...
Please review! I like kind, constructive criticism :)
