Sailing Omens
These are the start of various omens that exist currently. Other omens maybe added later.
Good Omens
1: Setting sail at dawn is wise because Terashi as just succeeded in chasing way Seizan.
2: A symbol of Chisei is always present on a ship.
Bad Omens
1: Never have a Flamekin on a boat. They are living fire and rock; both of which are not welcome on the ocean.
2: Never set sail at night. Seizan struck a deal with man, He would teach them to read the stars in order to navigate in his domain. In exchange, any ship that sets sail after dusk is his to claim if he wishes.
