For those unfamiliar with Spelljammer, Dwarven Citadels are small asteroids taken over dwarves and turned into Mines/Forges/Fortresses for the clan. The clan will eventually abandon the citadel for another asteroid or to split the clan leaving it an empty asteroid fortress pirate ready.
The Gravity Plane is a key feature, delineated by the Solid Gray regions. F1 and B1 effectively share the same floor and are on opposite sides of the gravity plane (the direction for up switches as you cross the gravity plane). So all the "F" floors are standard gravity, but the "B" floors are reversed.
