Laboratory Floor Grill (Rani's Laboratory)

A rectangular metal grill embedded flush in the laboratory floor near the TARDIS console, its hinged crossbars adjusted to access subfloor mechanisms. The grill’s edges show signs of recent tampering, its frame slightly warped where Beyus pried it open moments before. When disturbed, the grill emits a low metallic scrape against the floor tiles, drawing immediate attention to its loosened state. The Doctor and his companions recognize it as a deliberate trap—rigged to collapse into a pit or release toxic fumes upon activation.
