Baltigo, labeled as the "Land/Island of White Soil" (白土の島 Shiratsuchi no Shima?), is an island located somewhere in the Grand Line. The island's existence was long shrouded in mystery but finally became known to the whole world after the Zou Arc. Baltigo was destroyed during an intense battle with the Blackbeard Pirates.
The landscape has tall rock pillars and the ground looks like it might be snow-covered. It is also very windy there. The island has some ancient ruins that served as the headquarters of the Revolutionary Army.
The island served as a hub of information for the Revolutionaries, and is a home to their leader Dragon and the other members.
After arriving at Baltigo, an amnesiac Sabo started training under Hack, however, his body remembered his time training with his siblings, and he quickly abandoned the class in favor of personal training, achieving a fighting level of the top members of the army.
