Well all though he does, have an Andoran view at times. He isn't trying to push that far into democracy. Because he even states himself, "The world isn't ready for something as far into the future. All that I do propose is one political step towards a future."
So he's more leading the stepping stones. Not full out democracy. He's leading the stepping stones.
As stated he doesn't believe in democracy.
He believes in leading steps towards a better political future. Whether that be democratic or not. All he wants is a more refined political standpoint.
Alright, a scion of the aristocracy wanting sweeping reforms in his society is not an impossible concept (and historically after all, such types have existed and pursued such things even at the expense of their own power), it just means that in pursuing them somewhere like Taldor requires some measures of subtlety and nuance as the more outspoken you go, the more enmity you are going to have from people who like the way society works just fine. Particularly, the more you openly sympathize with Andoran, former Taldan vassal state, the more you might find yourself in troubles your dad might have to bail you out of.
It's enough to hang a full concept on at least, but when fleshing it out, there are things to bear in mind. Amongst them, give the first post of the thread a decent eyeballing, it has important links that flesh out the setting and otherwise provides a good capsule of what the game is trucking in.
Beyond that, you'll also want to get into stuff like..
What is the history of your family? Were they elevated to the royal caste by the Grand Prince? Are they one of the truly ancient founding families? How long have they existed otherwise? What is their resource base like and what do they otherwise focus on? What kind of class levels does your character have and why? Are you trying to advocate for change publically? Secretly? Both? Do you have any kinds of ties to Andoran?
