Eldianology
A discipline that focuses on the study of Eldian history, people, cultures and politics. It also studies the Subjects of Ymir and the origin of power of nine titans that brought massive economic and military to the ancient Eldian empire, but also can threaten the other nations. The discrimination and racism toward the Eldian people is one of main topics of this study, and its solutions are still debatable to this day.
Sterilization of the entire Eldian people is Bob's favorite topic in eldianology.
