The Red Line is a long continent that stretches across the entire world, from North to South, along the equivalent of Earth's Prime Meridian.

While the continent appears impossible for any boat wishing to cross between the seas or to certain sections of the Grand Line, there are certain pass points at which a ship can cross between the Blues: up and down the waterways across Reverse Mountain (typically used to enter the Grand Line by pirates), by gaining government permission from the holy government land of Mariejois, or by submerging into Fishman Island which is placed around a hole that links directly between Paradise and the New World.

Any on their way to the Grandline without cutting through the Calm Belt must post their travel in this forum.
