Coraluna Whether in the Underrealm, or sailing the vast seas, people survive, and civilization grows.

Nearly ninety percent of Coraluna is ocean, broken only by scattered continents and island chains, yet the world is far from empty beneath the waves. A vast network of caverns, chasms, and subterranean kingdoms stretches across the planet’s depths. Entire nations thrive in these massive underground expanses, while isolated communities carve out lives in the darkness and nomadic tribes battle the untamed wilderness far below the surface. Bioluminescent forests, geothermal seas, colossal mushroom groves, and ancient magic—older than any known civilization—bind this hidden world together.

As the peoples of Coraluna move beyond mere survival, developing trade, industry, science, and culture, a new Age of the Arcane has begun. Knowledge spreads, power shifts, and long‑dormant forces, both mortal and divine, are rising once more.
