The Bigail Channel is the body of water that lies between the Isle of Bigail and mainland Valorim. It is notorious for rocks, many of which can sink a ship if unwary. To combat this, the Empire established Northpoint Lighthouse and [[Southpoint Lighthouse. There are three trade routes for ships that connect Bigail with Midori Province, Krizsan Province, and Karnold Province. They are Shayder-Marish, Port Townsend-Farport, and Fenris Port-Softport respectively, with the Bigail-side port listed first.
