The Coast War
Foalton and Port Ralono have different cultures. Port Ralono is unwelcoming to off-islanders and Foalton’s culture requires them to welcome them warmly. Their differences sparked fights between drunken men at bars. This caused people that had weapons to start fighting. The law enforcement tried to break these people up, but then started fighting the enforcers of the other town. People started attacking and defending themselves.
Eventually, Port Ralono soldiers dug their way to Foalton. The fight began underground. Sorcerers were being used in war now, and because of this, an arcane explosion occurred, killing many soldiers and pushing tons of ground upward to form Nahoto hill, named after the nihoto sword.
