The Grand Duchy of Tynor is in all senses the Royal Demesne, as the Grand Duke has always been one of the ruling family, usually the heir. It is significantly larger than the other duchies of Edrane , responsible for it's status as a Grand Duchy(Think the Archduchy of Austria). In both economy and manpower, it is also the strongest when individually compared to the other duchies and counties of Edrane, largely because of it's size and because of Coil, an extremely major hub of trade between Andoras and Doras Edrossi .
