Gradoslavl
Gradoslavl was the province that united the other lands into the kingdom of Triman. While the tzar has traditionally had support from Gradoslalv, it sided against tzar Vsevolod the Cruel in the civil war. After the death of the tzar, and with kniaz Vratslav taking the oath of the copper guard, Gradoslavl has been in decline. Still, this province is the most inhabited one as well as the one with most cities. Gradoslavl has a strong claim to the throne as traditionally, almost every tzar has been a Gradoslavian kniaz. However, the current ruler is not a close relative of the late Tzar, which weakens the claim
This province is strong on trade. While other provinces might have natural resources, almost all trade routs pass through Gradoslavl. They are also the biggest farmland of Triman and have many craftsmen.
