Lily apparated to her own chambers, a large room with two floors, her bedroom on the top floor and an office below. The office was cramped by a large circular wooden table and dark as the windows were blocked. Lining the walls were an array of endless bottles of different sizes containing fluids of every colour imaginable. The light streaming through these bottles shined in different hues, given the effect that the room was surrounded by stain-glassed windows. There were no labels on any of the bottles, as Lily could tell each potion by the colour and viscosity of the liquid. At the centre of the table was the silver-crowned Diadem of Ravenclaw. Unusually, Lily had no scrolls, books, or parchment paper for one so studious, preferring to keep the knowledge in her head. It was after she had started wearing the crown that Lily realised she could recall passages of books, even entire position recipes (including the quantities of each part), without the need to refer to the original text. It seemed to be fated to fall into her hands, and she was certainly grateful for the boon it had offered her.
