Kingmaker - Rivers Run Red
Brevoy (pronounced BRE-voy) is a nation in far northeastern Avistan on the verge of tearing itself apart. The political entity known as Brevoy was once two vastly different nations locked in a constant state of war before being conquered by a despot. After centuries under the rule of a line of conquerors that only recently disappeared, Brevoy must now decide its own destiny.
Being so far north, winters are long and harsh. The short spring and summer seasons require the populace to farm and fish just enough to keep food on the table
