[quote=@GreivousKhan]Also as a side note, stay away from names with 'states' plural in it since technically you are a provincial state as it is within a larger nation. It would be like calling Florida the United States of Florida while it is in the Untied States of America.[/quote]

I'm not sure about that. This is a world encompassing empire that is assumedly highly ethnically and culturally diverse. It would make perfect sense, both geographically because of the scale and politically because of decentralization, for the constituent states of this empire to themselves consist of a number of sub-divisions, possibly with large degrees of autonomy.
