The Shattered Tides

Medieval Earth fractured by the Great Sundering 50 years ago when dimensional rifts tore open the veil between worlds. Mana flooded in, transforming the planet into a cultivation world. Dungeons spontaneously form in places of concentrated mana. Mana storms rage across oceans and coastlines, offering dangerous opportunities for those brave enough to cultivate within them. Technology remains medieval, but mana-infused artifacts and spirit vessels have emerged. The seas have become the most dangerous and opportunity-rich zones, where pirates and cultivators hunt treasures from rifts and storm-touched islands.

The Seven Shattered Seas dominate the world - vast oceans broken by archipelagos of storm-twisted islands. Major powers include the Jade Merchant Confederation (controls eastern trade routes), the Iron Throne Admiralty (military naval power), and the Free Reef Coalition (pirate havens and independent islands). Mana storms cluster around rift zones, creating ever-shifting danger zones rich with spirit stones and dungeon portals. Ancient pre-Sundering ruins dot coastlines, now dungeons filled with treasures and monsters.

Primarily human, though mana exposure has begun creating variants - Storm-Touched (those who survived mana storms and gained elemental affinities), Rift-Marked (dungeon survivors with strange abilities). Pirates, merchants, and naval powers all compete for control of storm routes and dungeon access. A cultivation hierarchy has emerged based on mana core advancement.

The Crimson Tide War - a three-way struggle between the Confederation, Admiralty, and Free Reef Coalition over control of the Dragon’s Maw, a massive permanent rift that spawns the richest dungeons. Mana storms are growing more frequent and more violent, threatening coastal cities. Ancient things are awakening in the deepest rifts, and rumors speak of a prophesied Tenth Storm that will reshape the world again.

Cultivation system based on absorbing mana from spirit stones, defeated monsters, dungeons, and mana storms. Ranks: Awakened → Spirit Sailor → Storm Breaker → Rift Walker → Tempest Lord → Void Emperor. Old gods are dead or silent since the Sundering. Some worship the storms themselves or the mysterious entities glimpsed within major rifts.

Rifts connect to other dimensions, spewing monsters and treasures. The most powerful cultivators can force their way into rift zones to hunt. Mana storms occur when planar boundaries thin, creating cultivation opportunities for those strong or insane enough to weather them.

Pre-Sundering Era (peaceful medieval Earth), The Great Sundering (50 years ago - dimensional barriers shattered), The Awakening (first generation learns cultivation), Current Age of Storms (rifts stabilizing, cultivation society forming, power struggles emerging).

Spirit stones are primary currency among cultivators. Storm-touched materials, dungeon cores, and rift treasures drive the economy. Trade routes follow safe passages between mana storms. Piracy is rampant, with some pirate lords more powerful than nation-states.

Might makes right in most of the Shattered Seas. The strong are revered, the weak serve. Adventurers/pirates are feared and respected - they brave dungeons and storms for power. National laws exist but cultivators above Storm Breaker rank often operate beyond them. Pirate codes hold more sway than national laws in many regions.

Rift Spawn (creatures from other dimensions), Storm Beasts (elementals born in mana storms), Dungeon Lords (powerful monsters that rule dungeon depths), The Leviathans (ancient sea creatures awakened and empowered by mana), The Cult of the Tenth Storm (believes they can trigger the prophesied apocalyptic storm), rival pirate lords and cultivation sects.
