The Sea of Fallen Stars—often called the Inner Sea—forms the liquid heart of Faerûn, its vast blue expanse threading together east and west, north and south. Bordered by the bustling coasts of Cormyr, Sembia, Chessenta, and Thesk, its waters churn with merchant ships, war galleys, and adventuring vessels whose sails rise and fall with the promise of trade and danger. Beneath the waves lies Serôs, an ancient, submerged realm of aquatic elves, merfolk, tritons, and coral citadels, where magic pulses like tides. Yet not all is peaceful—sahuagin raiders, aboleth cults, and the occasional kraken disturb the watery deep. Massive dragon turtles roam like leviathans, hoarding secrets and crushing trespassers. Scattered islands—Isle of Prespur, Tharsult, and others—dot the sea like glittering jewels, some hosting ports and fortresses, others overgrown ruins and lurking threats. A vital nexus of civilization and mystery, the Sea of Fallen Stars is as essential to Faerûn's lifeblood.

Endless blue waves shimmer under the sun, dotted with white sails and distant island silhouettes. Coastal cities gleam along the horizon, their harbors alive with ships and shouting merchants. Beneath the surface, coral reefs and ruined spires pulse with magic, patrolled by sinuous shapes. Stormclouds gather over open water, hinting at sudden danger, while dragon turtle humps break the surf like moving islands. The sea whispers of wealth, war, and wonders untold.
