He is also only the second person to ever hold the title, the first having been assassinated within months of taking power.
The name, while having no martial or magic bolstering effects, is more subtle in allowing the holder to sway large groups. This power works similarly to how the Empress or the Heiress names allow holders to manipulate individuals. This name is most effective in swaying nations to either wage war or compromise for peace. The ability manifests in Anaxares's mind as a sentence to convince individuals for one action or another.
The role of the Hierarch is to offer stability. As the diplomat Anaxeres was exposed to the Tyrant of Hellike and his war, he gained a name that allows him to work in the opposite direction. Anaxeres, in his previous position as a diplomat for a democratic country, was well suited to unite the free cities at a time when their united strength was needed. Thus, the Hierarch has power to mend and unify countries.
The main powers of this name are to manipulate other with words as well as slight precognitive abilities such as the Augur while also having similarities to the Bard's ability to home in on individuals that are critical to creation.
