I'm guessing you're playing Ermor, in which case that is the name of your theme. Notice that when creating your god you can pick other special Ermor themes - Ashen Empire and Soul Gate - which are drastically different from playing Broken Empire Ermor.

This means that the province has your dominion in it and that you are playing the Broken Empire(default) theme of Ermor.
Thanks. I kinda figured that. It's just that when I saw "Broken Empire (default)" in province info for provices I wasn't even in, I thought something was actually broken in the game. Such is the newbie life.
