While not related to the lore specifically, the planisphere or "star globe" seems to be very much based off the feng shui luopan, a magnetic compass that uses multiple plates to chart stars and leylines. A number of plates and dials are used to line up with the flow of chi and is most commonly used in divination.
As for the arcana themselves: the Seven Heavens.
The Spire is very much the Manipura "jeweled city" chakra. The Bole corresponds well to Muladhara, the root chakra. It's a little vague, but there are definite parallels between the six base chakras and the six arcana of the Astrologian. The seventh chakra is almost explained word for word with the Seventh Heaven, about opening oneself up to the power cosmic of the universe.
