Kalassarian Empire
The Kalassarian Empire was a continent-spanning state that succeeded the Republic of the Kalassus in 21 PF. At its peak, it spanned from present-day Senera in the west, most of Tanduaria up to the Chokhul mountain range to to north, the western edges of present-day Sarebia in the east, and portions of northern Ralaka to the south.
Most Beteran states were either once a part of the Kalassarian Empire, or was heavily influenced by them, and many present-day states still claim to be the successor to its millenia of history.
