I am preety confused right now, let's say a pirate crew quits and wants to go home, how in hell are they going to leave the grandline to the 4 blue seas?
Looking at the map of OP, i see the red line, grandline and the 4 seas, on 2 spots the grandline is blocked, on the first one by the reverse mountain who has acces from all sees leading to the start of the grandline, on the other side though there is no acces from the NW to reverse mountain aka the 4 seas. And on the half of the grandline we have the Fishermen island and Marijoy. Again no exit.
And since the calm belt surounds the Grandline you basicly have no way out of it? Even if you became pirate king btw, not sure how Roger ended up in Loguetown....
