In a magic-enhanced realm, there exists a room where the gravity reverses for anything not nailed down when a specific incantation is uttered. The room is a typical class setup with a single door, desks and chairs, papers, pens, etc. The ceiling is adorned with beautiful chandeliers. Zephyra enters the room wearing a flowing scarf and loose clothing, carrying a metallic, enchanted briefcase that always orients itself towards the ground no matter the direction of gravity. Zephyra utters the incantation to reverse gravity as she's standing in the center of the room. What happens to Zephyra, her attire, the contents of the room, and what can she see as gravity is reversed?
Upon Zephyra uttering the incantation, gravity's direction changes for everything in the room that isn't secured. Zephyra, her loose clothing, her scarf, the desks, chairs, papers, and pens all start to float upwards towards the ceiling. As the gravity has reversed for these objects, they accelerate towards the ceiling similar to how they would fall toward the floor under normal gravity conditions.

Zephyra's attire, not being secured, also starts to float upwards. Her flowing scarf begins to rise above her head, and if not held down or attached to her, would continue to the ceiling. Her loose clothing billows around her as if she were underwater. Items such as pens and papers not fastened down would drift upward, scattering and turning in the air, while the chandeliers remain firmly attached to the ceiling because they are nailed down.

Zephyra's enchanted briefcase, however, behaves differently. Because the briefcase is designed to always orient itself towards the ground, it does not follow the reversed gravity like other objects. The briefcase would remain firmly in Zephyra's hand or on the floor where she places it, unaffected by the change in gravitational direction, possibly appearing to float relative to the rest of the room's contents.

As she is now effectively falling toward the ceiling, Zephyra would see the room upside down. She would watch as unsecured objects around her pass by on their way to the ceiling. Should she try to navigate the room, she would need to move along the surfaces that are now effectively the 'ground' from her perspective, or swim through the air, pushing off the floating objects to propel herself in the desired direction.
