Location from Harry Potter by J.K. Rowling
The ancestral London townhouse of the Black family, hidden by a Fidelius Charm and used as headquarters for the Order of the Phoenix, filled with dark artifacts, cursed portraits, and the screaming painting of Mrs. Black.
Number 12, Grimmauld Place is a house that hates most of the people living in it. Built by the Blacks — one of the oldest pure-blood families — it is saturated with dark magic, anti-Muggle enchantments, and the accumulated prejudice of generations. Sirius Black inherited it and loathed it, trapped in his childhood prison while the Order used his dining room for war councils. The house resisted the Order's presence at every turn: the portrait screamed, the curtains wouldn't budge, Kreacher muttered insults and hoarded dark artifacts. After Sirius's death the house passed to Harry, who used it as a base during the Horcrux hunt. Kreacher, won over by kindness and the truth about Regulus, eventually transformed from hostile to fiercely loyal — and the house seemed to warm slightly in response.
A tall, grim townhouse that materializes between numbers 11 and 13 when you know the secret. Inside: peeling wallpaper, gas lamps, a troll-leg umbrella stand, mounted house-elf heads on the staircase wall, and a permanently stuck portrait of Walburga Black who screams 'BLOOD TRAITORS! FILTH! SCUM!' whenever the curtains over her frame are disturbed. The kitchen in the basement is the only warm room, where Order meetings take place around a long table. Kreacher the house-elf shuffles resentfully through the halls.
