Emperor of Keltoia (Vae victis!)

The Emperor of the Keltoi (Known natively as the Oljawalosalv), was the most important political, economic, and military leader in the Keltoic Empire. While the decentralization of the Keltoi severally limited any Emperor's ability to rule, they still had a massive amount of influence over their nation. For example, a given Emperor could set taxes, raise armies, and even depose of Chieftains. However, despite their theoretical unilateral power, the Emperorship was often reduced to a turf war between the Emperor and his Chieftains or the Senate. this would make the Keltoic Emperor one of the weaker European monarchs, in spite of the powerful nation behind him.
