I think something people skip over a lot in the Astrologian job quest is how they call Geomancers style of divination the foil to Astrologian, the setting of a contrast between the two schools. This is also likely meant to draw attention to the real world counter parts of Western Astrology and the Eastern Feng Shui.

"While astrology focuses on the personal destiny of the individual and Feng Shui focuses on the SPACE and addressing the environment, there is an overlay between the two predictive arts which is very complementary and historically they have been practiced together."
