Ethereal Expanse- 4th Sea

The Ethereal Expanse is a vast and mysterious oceanic layer of the multiverse, intricately connected with the material plane which is it's largest "land mass", with the swirling elemental energies above from the Elemental Vortext. It exists as a realm suspended atop the dark clouds of the Tempest Sea, a tumultuous expanse of roiling storm clouds and crackling lightning.

• Floating high above the stormy depths of the Tempest Sea, the Ethereal Expanse is dotted with countless floating islands, known as planar islands. These islands vary in size and shape, ranging from small atolls to sprawling landmasses, and each one is a unique microcosm of life and civilization. Created settlements, both humble villages and majestic cities, cling to the rocky shores of these islands, built from materials native to the ethereal realm.
• Travelers traversing the Ethereal Expanse must remain ever vigilant, for the monsters that lurk in the depths of the Tempest Sea are a constant threat. Giant leviathans, their massive forms obscured by the swirling mists, prowl the ocean depths in search of prey. Spectral wraiths and otherworldly aberrations drift through the ethereal currents, their haunting cries echoing across the expanse.
