The Tidal Realm is an all-encompassing ocean without surface or air, a boundless expanse of water that defies the concepts of deep and shallow, dark depths, or sunlit surfaces. This plane is a pure manifestation of water in its myriad forms, enveloping visitors in an environment that simulates the sensation of being submerged a few meters below the surface in any ocean of the Prime Material Plane. The absence of a sun does not diminish the realm's visibility, for the waters themselves emit a soft, bluish-green luminescence, casting an ethereal glow that illuminates the endless aquatic landscape.
Within this infinite ocean, the water transcends simple categorization. Here, currents of varying temperatures and salinity coexist and intertwine, allowing for environments ranging from the warm, crystal-clear tropical waters to the icy currents of polar seas. This diversity supports a vast ecosystem of elemental and aquatic life, each adapted to the unique conditions of their surroundings. The realm's very essence facilitates exploration and navigation through intuition or the guidance of those familiar with its currents, revealing pockets of water that cater to every conceivable preference and necessity.
The Tidal Realm is teeming with life, hosting a spectrum of creatures and beings that embody the plane's elemental nature. From majestic water elementals that glide through the currents with ease to schools of luminescent fish that navigate the eternal ocean, each creature adds to the realm's vibrant ecosystem. Societies here are as fluid as their environment, with inhabitants residing in structures that harmonize with the ever-moving waters, built from coral, enchanted ice, or materials shaped by elemental magic.
The culture within the Tidal Realm is one of harmony and adaptability, with a deep-seated reverence for the water that sustains all life. Magic is woven into the fabric of existence, focusing on the ebb and flow of currents, the shaping of water in its countless forms, and communication through the ocean's own language of sounds and vibrations. Navigation and exploration are arts mastered by the realm's denizens, who can discern the subtle shifts in temperature and salinity to find their way through the endless waters.
Though isolated in its endless aquatic expanse, the Tidal Realm is intrinsically linked to the cosmos's balance, its waters a metaphor for the flow of life and the connectivity of all existence. Adventurers who venture into this plane discover a world where direction is moot, and the journey is measured in experiences and encounters rather than distance. The Tidal Realm offers a unique perspective on existence, where survival and exploration demand a surrender to the currents and an embrace of the realm's fluid nature.
The Tidal Realm demonstrates the elemental force of water, inviting those who enter its domain to experience the profound depth and serenity of an endless ocean. It challenges visitors to let go of terrestrial constraints and immerse themselves in the beauty and vastness of a world entirely composed of water, where every current leads to a new discovery and every creature plays a role in the realm's everlasting cycle of life.
The Tidal Realm, with its boundless oceans, hosts a variety of mesmerizing locations, each contributing to the plane's rich tapestry of aquatic life and elemental water magic.

Meridian is not only a political center but also a place of learning, where the secrets of the ocean are studied and preserved.
