The first day back at Hogwarts always felt like this. Cold air, the smell of rain on stone, and the low hum of voices bouncing off the castle walls as students dragged their trunks inside. Seventh year. Last first day. The Entrance Hall was packed with people hugging, laughing, comparing summers, complaining about classes they hadn't even started yet. Somewhere across the room, a first-year tripped over their robes and went down hard, books scattering across the floor.
