Early Childhood 1877-1883 Sirius is born in Hogsmeade in 1877, having a fairly uneventful early childhood where neither of his parents are very interested in him. Instead, exempting his nanny, he is primarily raised by his aunts; he can often be found shadowing Iola or Elladora, whichever is more likely to put up with him at the time. He is also generally unaware of the tempestuous events between his parents; namely, Ursula’s affair. While aware of his mother’s son (1881), Sirius is let unaffected when the child dies, too young and self-absorbed to grieve.

His aunt Iola is disowned in 1882 for reasons that Sirius does not entirely understand at the time - later he learns that she ran off with a muggleborn. He is distraught and inconsolable for weeks, throwing tantrums seemingly at the drop of a hat - the entire event gives Sirius persistent abandonment issues.

When he turns five (1882) his mother, through dubious and possibly traumatic tactics, manages to provoke Sirius’ first sign of magic in the Forbidden Forest. From then on their relationship becomes more of an actual bond, and Sirius is quite relentlessly loyal to her.

1883 brings the arrival of a brother, Phineas, whom Sirius dislikes largely because his position as an only child is unthroned. Ursula’s dependency on laudanum gives him a patience for such behavior, although he will likely not recognize it for what it was until later in life. 1884 brings Arcturus to the family, and Sirius surprises himself by liking the child. It is also around this time that he begins flying and has a bit of a talent for it; encouraged by his mother and a Mr. Thom Pettigrew Sirius becomes an avid amateur Quidditch player.

Move to London 1884-1888 Left unaffected by the plague inasmuch as he does not die of it when he is ill, Sirius does move to London with the rest of the family after the fire in Hogsmeade in 1884. 1886 brings Belvina with it - jury’s still out on that one. Sirius is rather excited to be going to Hogwarts in the fall of 1888.

Hogwarts 1888 - Present Sirius begins Hogwarts in the fall of 1888, where he is sorted into Slytherin. He becomes a chaser and is a clever, if not particularly motivated, student. His closest friends are Flora Mulciber and Abraxas Crabbe, and he has an off-and-on friendship with Hesper Gamp. In third year he picks Divination and Care of Magical Creatures as his electives.
