I went in with an Exchange person and past experience of trying to set up trade deals and establishing allies for the soceity. It turns out that little in the scenario really pushes you into overthrowing the Efreeti as most of her subjects and the one major NPC are not all the unhappy. Second class sure, but hardly worse off than slaves in Cheliax or humanoid cattle in Geb.
The worse thing she seems to do is take children away from the Oreads (bad) and give them status, an education and greater rights (YE GODS the HORROR) its again to blaming Daddy Warbucks for taking Annie away from the orphanage. It seems that the writer wrote this from a modern perspective rather than one more appropriate to the time and setting, and needed to really emphasize how bad off the oread were, and how she was looking to conquer the area, despite all the Oread descriptions saying well, its not great but its not all bad...
