1868. Harry is born the fourth child and second son of John and Alice Berkwood, an upper class muggle couple. He is a very active and inquisitive child. Most childhood reprimands come from his enthusiasm for getting into things he shouldn't.
1873. In what would later be seen as a clear and obvious sign of magic from Harry, the Berkwoods find themselves genuinely baffled when an entire tea tray seems to shatter despite no one touching it.
1874-1878. There are a few more incidents, scattered throughout the years, but mostly Harry enjoys a fairly happy childhood. He gains a particular interest in the sciences through the tutor his family hires, though he's fairly sure a life of Academia is not what his parents want for him. Oops.
1879. A strange man arrives in summer with even stranger news--Harry's a wizard. The Berkwoods are understandably skeptical, and a little uneasy, but for Harry, it seems like an exciting adventure. His parents are soon enough convinced, and it's off to Hogwarts in September. It is not a great shock when the Sorting Hat places him almost immediately in Ravenclaw. He takes an interest in most of his classes, but in Potions, it's like love at first sight. It's also hatred at first sight with Defense Against the Dark Arts. Can't win 'em all.
1881. Harry picks up Ancient Runes and Earth Magic as his electives.
1884. Harry sits his OWLs and does as well as one might expect--with one key exception. There's no [i]proof[/i], per se, that he flunked his DADA exam on purpose, but it really ought to be impossible to get as much wrong as he did after attending the class for five years. Surely something would have gotten in, at least. Come sixth year, Harry decides to keep Potions (of course), Herbology, Transfiguration, Charms and History of Magic, and picks up Alchemy as well.
1886. Harry leaves Hogwarts with high NEWT scores, but there's really no question of what he's going to do. He takes an apprenticeship in London, and frankly, he's the happiest he's ever been in his already happy life.
1888. Harry is mostly thankful to be outside of the fog during the summer, and continues with life as usual. Potioning. Experimenting. Harry-ing.
1893. Following the election of the new Minister of Magic, Harry is appointed to a committee for voting reform. He feels like a fish out of water, and the impostor syndrome is very real. But it's important, and he's taking it very seriously.
Also important, but in a very different way--Harry has a chance meeting with Avery Davenport and, more importantly, her daughter, Marigold, and is faced with the fact that his brother has a daughter they didn't know about. And just because Daniel has no desire or intention to take care of his responsibilities doesn't mean Harry can ignore them.
