G'day
In my campaign the hieracrhy of titles is actually Hegemon, Kreion, Anax, Kyrion (a term of address encompassing several titles at equivalent rank such as basileos, tyrannos, despotes, etc), medon, Aretos, eugeneios; or in the Decadent Period effectively Polemarkhos, Episkopos, Krites, Hypokrites, medon, eugeneios.
Last time I had a campaign with dwarves in it they used Scottish titles: king, thane, chieftain, etc.
An note ot a previous poster: 'thane' in Old English meant 'servant [of the king]', not 'head of the clan'. The head of a saxon clan was usually addressed as 'hlaford' (meaning, originally, 'loaf-giver').
