Seventeen years ago, the world changed. One man of implacable zeal and indomitable will, the Pirate King, met his end after sharing with the world the existence of his greatest treasure. Lust, greed, and pride brought a slew of pirates, invoking the wrath of the World Government and the Marines, starting something more akin to a war in this new age of piracy.

Some seas fared better than others: the Grand Line saw a boom of commerce as adventurers and pirates alike arrived, but with so many bloody accidents, costly miscalculations, and gruesome battles, the death toll seemed to rise much more. The East Blue remained mostly tranquil, as it had often been, as did the West. The North boomed loudly, but in the South, there was trouble. Though it was the largest of the seas by population, it did not have the peace of the East, the technology of the North, or the history of the West. Without the staying power of tranquility, craft, or tradition, the South saw the largest boom in piracy from the Blue Seas. Some tales traded of chaos at Reverse Mountain where too many ships tried to enter simultaneously in the dawn light, rushing as if One Piece was just on the other side. Worse yet, the increased piracy left less of the able bodied to defend cities, making it all to easy for failed pirates to return to their seas with many undefended islands to plunder. Some failed pirates turned to other avenues of crime, abusing the fact that the Marines and law enforcement were spread thin.

Countries fell, only to be replaced with new regimes, just to fall once again. Marines, fatigued from the constant struggle, fell to corruption and greed to ease their burden. The seas have quieted in parts, but under the surface lies a thick layer of blight, and thundering skies approach. The seas have never been stranger.

On Stranger Tides is a role play that is mainly based on One Piece; to not hinder your role playing experience, it would be best if you are familiar with the series. Following an Age of Romanticism, adventure and relative peace, this age is a fairly dark one. You can be anything you wish. Within reason, and as appropriate for the setting. An anthropomorphic captain of the guard trying to control the anarchic pirate town? Why not? Runaway prince from an underwater kingdom? Go for it! An mercenary working as a shipwright? Interesting! A intergalactic space marine? No. It is recommended to be something similar to a humanoid, but not required.

As written in the premise, players will start in the four blues, and then move on to tackle the Grand Line itself. More emphasis would be directed towards sailings and the journey in between islands. Improving your ship via parts and upgrades will be options granted to you. Goals throughout the story would probably include improving your skills and abilities, amassing wealth beyond your imaginations, become infamous beyond measure, and engraving your name in history to name a few.

Aside from certain elements of fantasy, you will eventually come to notice the level of technology in this world will be slightly advanced as compared to that in the manga. And if you were wondering, most of the canon characters are dead or retreated from the world altogether.
