God Valley

Sitting in the West Blue with no ties to the World Government, this island became the setting for the so called God Valley Incident roughly 38 years before the present day. Its terrain ran to towering cliffs and deep canyons, and one signature peak had cracked straight down the middle to leave a single immense ravine cutting from northwest to southeast. A small town built in an Old West style sat tucked inside that gorge. World Nobles prized the place for its plentiful natural wealth, and its population numbered no fewer than 100,000 souls before disaster struck.

For generations the island sheltered the Davy Family, descendants of the legendary pirate Davy D. Jones from eight centuries earlier, which made it the home soil of Rocks D. Xebec. Around 40 years ago Xebec entrusted a woman and their child to the Davy clan there for safekeeping. Figarland Garling later sailed in, fathered the twins Shamrock and Shanks with a local, and after spotting the island's riches pressed its people to join the World Government, an offer they rejected. Garling then proposed the site as host of the triennial Native Hunting Competition, a sport in which Celestial Dragons slaughtered locals and slaves, with the blasphemous sounding name used as a thin excuse for what was really revenge against the holdout population.

During the incident itself, Nerona Imu's arrival twisted Rocks into a demon who turned on his own Rocks Pirates. A clash with Edward Newgate toppled one of the island's peaks, and the forced alliance of Monkey D. Garp and Gol D. Roger against Rocks brought the second mountain down too. Once Garling killed Rocks, the entire island caved in and sank beneath the ocean, and Imu's interference saw it declared to have never existed, erasing it from world maps. Unaware of the wider story, the Roger Pirates carried off the World Nobles' treasure and found an infant Shanks hidden in one of the chests, taking him aboard as an apprentice. The island is remembered as the birthplace of Shanks, his twin Saint Figarland Shamrock, Rocks D. Xebec, and a haven for Rocks' son Marshall D. Teach.
