G-1

G-1 was a Marine base in the New World. However, following the events of the Battle of Marineford, its location has been moved to Marineford, with Marine HQ replacing G-1's former location. The Fleet Admiral after Sengoku wanted the new HQ to be in the sea of the Yonkou. It is said to be exactly symmetrical to Marineford on the other side of the Red Line.
