Pieces of broken and disused machines of unknown function lie all around. Before you stands a horizontal wooden wheel, rusty iron spikes rising from its rim, its spokes, and its hub. Heavy iron rings hang from the walls. Protruding wooden beams bear pulley-blocks and ropes and chains. Windows in the walls and pillars lead not to the outside, but to further internal spaces: cells, storage rooms, and empty voids.
To the west is a massive iron-bound wooden door. A staircase leads up to the south and then bends east. There are wide archways to the north and east, and in the north-west corner a narrow staircase leads up into darkness.
Suddenly a raven flies past, the clap of its wings breaking the near-silence of these halls. "Raak," it cries, and vanishes into the darkness.
