An Annux is a ruler who is considered higher than all others, as mentioned in the book The King of Attolia. The term is derived from the Greek Anax, which means king. In contrast to the title Basileus, another archaic term for king and ruler of people, Teleus describes Eugenides as an Annux to distinguish the fact that he will be a "King of Kings". By deferring his sovereignty of Sounis to Attolis and that of Eddis's sovereignty impending their marriage, Sophos effectively makes Eugenides the annux of the three nations at the conclusion of A Conspiracy of Kings.
