That oh-so-secret Thief’s oath intrigues me because, I agree, we are given every indication that Eugenides is still bound by it. If that’s the case, he has to always make sure that his oath to the country and people of Eddis is not in conflict with the oaths he’s made to Attolia as its king.

At this point the interests of the two countries are in alignment so there is no conflict in loyalty, but really that’s because Eugenides has made sure that to keep it that way. Juggling his potentially competing loyalties as Thief and King—just one more thing this poor guy has to worry about.
