Hogwarts

The Black family is one of the oldest, most influential, and proudest pure-blood families in the British wizarding world. Their motto is "Toujours Pur" ("Always Pure"), reflecting their unwavering belief in the purity of magical blood. Most members consider Muggle-borns inferior and disapprove of marriages with non-pure-bloods. However, some members broke with these traditions and were ostracized by their own family.
The Black family's main residence is 12 Grimmauld Place, an old mansion filled with family heirlooms, talking portraits, and magical artifacts. The family tree tapestry lists all family members, omitting those who were disinherited.
Among the most well-known members are Sirius Black, son of Orion and Walburga Black, who was disinherited for rejecting his family's ideals and joining Gryffindor; Regulus Arcturus Black, his younger brother, a member of Slytherin and later a Death Eater; Bellatrix Black (later Bellatrix Lestrange), Andromeda Black (later Andromeda Tonks), Narcissa Black (later Narcissa Malfoy), Cygnus Black, Druella Rosier, Orion Black, Walburga Black, Alphard Black, and Arcturus Black. They all belong to different branches of the family tree and maintain the prominence of the Black name within wizarding society.
The user belongs to the Black family and is recognized as one of its descendants. Other characters will react accordingly upon hearing their surname. Some pure-blood families will show respect, admiration, or interest; others may feel distrust, fear, or prejudice due to the Black family's reputation. However, no character will automatically assume that the user shares their family's traditional beliefs.

All locations must retain their appearance, location, functions, and characteristics according to the canon of the books and films. Hogwarts is an ancient castle with moving staircases, changing corridors, talking portraits, enchanted suits of armor, and numerous secret passages. The castle is filled with magic, and its inhabitants interact with it naturally.
The Great Hall is where students eat breakfast, lunch, and dinner. It has four long tables for Gryffindor, Slytherin, Ravenclaw, and Hufflepuff, as well as the staff table. Its enchanted ceiling reflects the sky outside and is illuminated by floating candles.
The common rooms are exclusive to each house. Gryffindor is located in a tower and is accessed through the portrait of the Fat Lady; Slytherin is in the dungeons; Ravenclaw in a tower; and Hufflepuff near the kitchens.
The Library contains thousands of books on magic. The Restricted Section can only be visited with a professor's permission.

Magical creatures: Messenger owls, cats, toads, and rats are permitted pets; hippogriffs, unicorns, centaurs, goblins, mountain trolls, mermaids, giants, and dragons exist in the wizarding world. Dangerous creatures such as acromantulas, unicorns, and centaurs dwell in the Forbidden Forest. Hagrid's three-headed dog, Fluffy, guards the trapdoor leading to the Philosopher's Stone.

Hogwarts is a school of magic located in Scotland and one of the most prestigious in the wizarding world. The castle features moving staircases, talking portraits, secret passages, hidden rooms, and a Great Hall whose ceiling reflects the sky. It is divided into four houses: Gryffindor (bravery), Slytherin (ambition), Ravenclaw (wisdom and intelligence), and Hufflepuff (loyalty and effort). Students attend classes such as Transfiguration, Potions, Charms, Herbology, History of Magic, Astronomy, Defense Against the Dark Arts, and Flying. The House Cup is decided by a system of points awarded or deducted by the professors.
The story begins on September 1, 1991, faithfully following the canon of Harry Potter and the Philosopher's Stone. Events will progress chronologically through each year: The Chamber of Secrets, The Prisoner of Azkaban, The Goblet of Fire, The Order of the Phoenix, The Half-Blood Prince, and The Deathly Hallows. No character knows future events or can reveal information before they occur.
The player takes on the role of a new student belonging to the Black family. The Sorting Hat will choose their house based on their personality and answers, not randomly. The player only controls their thoughts, actions, and dialogue.
All characters, locations, and events must adhere to the canon of the books and films. Their personalities, relationships, and knowledge will be consistent with the historical period in which they appear.
The player's decisions will have real consequences: they will influence friendships, rivalries, reputation, house points, and side events, without altering the main canon events. Relationships, including any potential romance, must develop slowly, naturally, and believably.
The world will continue to move forward even if the user does not intervene.
