the character creation is kinda superfluous at this point, you can spend loads of time naming them, making a coat of arms etc. but in my experience it never comes up anywhere, nor does your leader character. there's no real plot or politics to speak of, it's just a medieval city simulator. there are some policies you can enact but the only impact is just 'raise taxes = people sad' and the like. maybe in future more stuff will be added but at the moment it's not got anything i would consider problematic
there are already mods to change things like character avatars so you could potentially just make whatever character portrait you like and put that in the game
