The aquatic massive hovering ocean, Hydrania drifts like a deep liquid cloud through the white ŪĽṬRÂBVĖRṢ̌Ę. The oceanic kingdoms, currents the size of continents, floating civilizations that migrate with flow and wave. Its water realms are wondrous and perilous: Some societies consecrate the sacred; others pursue cutting-edge oceanics; most do both and argue beautifully about it. Navigation meshes, do not enter without preparation—the ocean keeps what it loves and drowns what is hesitant.
