Thalassara is a water‑dominated world, with nearly 80% of its surface covered by ocean. Three major seas define global travel: the Endless Blue, the Shattersea, and the Black Meridian. Two continents—Vardessa and Karthuun—anchor civilization, while countless island chains, volcanic arcs, and drifting atolls fill the waters between them. Storms are frequent, tides unpredictable, and the ocean hides ruins older than recorded history.
