Location and political borders
Tyra is located on the Great Inland Sea, which makes up their southern border. Across the sea to the south lies the empire of Carthak. To the east lies Maren and Sarain, to the northwest lies Galla and Tusaine, and to the west lies Tortall.
Tyra is made of mostly swampland, which doesn't allow for much agriculture.
Tyra is a republic run on banking and merchants. Needless to say it is a mercantile society.
As Tyra relies mostly on trade and mercantilism as a source of income, it has trade relations with many countries, including those on the Emerald Ocean. In 463 HE, when it was revealed that Imajane Rittevon and Rubinyan Jimajen had assassinated King Dunevon, a boy-king, Tortall and Maren withdrew their trade from the Copper Isles, but Tyra did not, as it is known as being less concerned with where they get their money.
Like many countries, Tyra has agents in every country near them. Taybur Sibigat believes that Tyran agents have very slipper personalities, and thinks it comes from living in a swamp.
