Sophie Antoinette is a ruler in the Colonial Age, ruling Troulope, Lavignon and Narcien.
She is a queen and is married to Louis XXI. She is extremely unpopular among her people, because although her people are starving, she (and her husband) spends large amounts of money on their expensive lifestyles. She likes to throw parties and although does not care for the people, doesn't appear to be bad at heart. When you defeat her, she flees to her husband's lands. After you take Varseilles, she and Louis XXI are sent into exile by Victor Bonneparte, the leader of the revolution that resembles the French Revolution.
She is based on French queen Marie-Antoinette.
