Welcome to Naviri, a peaceful paradise full of promise—and in dire need of heroes.
It’s a gorgeous archipelago in which crocs, turtles, humans, and fish-folk trade, travel, and study. A world of cooperation, science, delight, and celebration.

But like any society, Naviri has its share of dark corners, dark dealings, and dark characters. And far out at sea, the Fold, which for years has kept the great sea monsters at bay, is failing. A new generation of heroes is needed to protect Naviri from these growing threats—and whatever else is waiting to break out of the Fold.

Explore Naviri. Work with your friends to keep your home safe and thriving. You may find yourselves gathering hard-to-find items, tracking down dangerous thieves, or battling a sea monster so massive and horrifying it has a volcano on its back. All while racing watercrafts across the sparkling sea, befriending local wildlife, and competing in contests of skill and strength to become one of the greatest heroes defending Naviri against creatures from beyond the Fold: a Tidal Blade!
