The Third Sub-Level of the Palace looked a lot, in Hermione’s opinion, like the Department of Mysteries back at the Ministry. Once she had followed Harry through the revolving elevator of Godric Gryffindor’s suit of armour, she found herself at the end of a cool, shadowy corridor that looked more like the deepest emerald green than simple black. Numerous recessed doors were set into the shiny, dark-tiled walls and the crackling torches produced only insignificant light, giving the whole place a spooky air of subterfuge and secrets.
