A riding of Armada, also known as the khepri quarter, or the Clockhouse Spur.
Inhabited and ruled by khepri who took over the running of the Grand Gears Library from the riding's previous rulers in a peaceful coup upon their arrival a century before the novel's start.
Somewhat dull-colored khepri-spit statuary decorates the riding, and guard-sister trios emulating their deities protect its decks.
Adjacent to Garwater.
The Pinchermarn, Corrosive Memory and Dancing Wight are some of the vessels that make up the Grand Gears Library.
