From Pathfinder Wiki:
As the birthplace of the Aldori dueling style, the city boasts several Aldori and Taldan dueling schools, which has led to the city being a favored place for young nobles to practice dueling championships. A large amount of Aldori duelists came to the city from Rostland after Choral the Conqueror united Brevoy.
Many firebrands who oppose King Noleski Surtova also hide amongst the taphouses of Restov, raising dissent. More recently, the citizens of Restov have become troubled about the politics and tensions between Rostland and Issia to the north.
