Dumbledore & The Order of the Phoenix

Explanation: Albus Percival Wulfric Brian Dumbledore. Born circa 1881, a professor then Headmaster of Hogwarts. He collects official titles: Chief Warlock of the Wizengamot, Supreme Mugwump of the International Confederation of Wizards.

Explanation: Godric''s Hollow — a mixed wizard-Muggle village in the West Country of England. It''s also the birthplace of the Peverell brothers and where the Potters are killed by Voldemort in 1981. Harry returns there in Book 7 to visit his parents'' grave.

Explanation: Aberforth Dumbledore. Infamous for casting inappropriate charms on a goat in his youth. He resents his brother Albus for Ariana''s death. In Book 7, he helps the trio enter Hogwarts through a secret portrait for the final battle.

Explanation: Ariana. Attacked by Muggle boys as a child, she became magically unstable (an Obscurial). Her death at 14, during a chaotic duel between Albus, Aberforth, and Grindelwald, haunts Dumbledore forever — no one knows who cast the fatal spell.

Explanation: Gellert Grindelwald, his youthful friend turned tyrant. As teenagers they dreamed together of dominating the Muggle world "for the greater good". Dumbledore locks him away in his own prison of Nurmengard after this legendary duel.

Explanation: Sherbet Lemons (lemon sherbet candy). A trivial detail that shows his taste for little Muggle things. Harry learns about it in Book 1 when McGonagall grumbles at his somewhat "childish" sweet-tooth passion.

Explanation: Thick woollen socks. Dumbledore jokes "one can never have enough socks at Christmas". Harry only realises much later, in Book 7, that Dumbledore obviously lied — he probably saw his lost sister Ariana and his family.

Explanation: Minerva McGonagall, former Deputy Headmistress, Transfiguration professor, and Head of Gryffindor. A tabby cat Animagus, she led the defence of Hogwarts during the Battle. She is still Headmistress at least until 2019 (Cursed Child).

Explanation: Kingsley Shacklebolt, a respected Auror with a deep voice and dangling earrings. He was secretly protecting the Muggle Prime Minister in Book 6. He is named acting Minister at the end of Book 7, then officially confirmed.

Explanation: The Gaunt Ring, which also contains the Resurrection Stone. Dumbledore finds it in the Gaunt shack and puts it on, unable to resist the urge to see his dead family again. The curse blackens his hand and would kill him within a year — Snape intervenes.
