Ravenloft: Curse of Strahd
The Planes of Existence
The Material Plane
The Material Plane is the nexus where the philosophical and elemental forces that define the other planes collide in the jumbled existence of mortal life and mundane matter. The rest of the multiverse is defined in relation to the Material Plane.
The worlds of the Material Plane are infinitely diverse. They include magic-wasted desert planets and island-dotted water worlds, worlds where magic combines with advanced technology and others trapped in an endless Stone Age.
The Material Echoes: The Feywild and The Shadowfell
The Material Plane is a richly magical place, and its magical nature is reflected in the two planes that share its central place in the multiverse.The Feywild and the Shadowfell are parallel dimensions occupying the same cosmological space, so they are often called echo planes or mirror planes to the Material Plane. The worlds and landscapes of these planes mirror the natural world of the Material Plane but reflect those features into different forms — more marvelous and magical in the Feywild, distorted and colorless in the Shadowfell. Where a volcano stands in the Material Plane, a mountain topped with skyscraper-sized crystals that glow with internal fire towers in the Feywild, and a jagged rock outcropping resembling a skull marks the spot on the Shadowfell.
The Feywild, also called the Plane of Faerie, is a land of soft lights and wonder. It is a realm of eternal twilight. The sky is alight with the faded colors of the setting, or perhaps rising, sun. But, in fact, the sun never truly sets or rises; it remains stationary, dusky and low in the sky.
The Shadowfell, also called the Plane of Shadow, is a darkly lighted dimension, a world of black and white where color has been leached from everything. It is a place of toxic darkness that hates the light, where the sky is a black vault with neither sun nor stars.
The Transitive Planes: The Ethereal and The Astral
The Transitive Planes are mostly featureless realms that serve primarily as ways to travel from one plane to another.
The Ethereal Plane is a misty, fog-bound dimension that is sometimes described as a great ocean. Its shores, called the Border Ethereal, overlap the Material Plane and the Inner Planes. Certain creatures can see into the Border Ethereal. The depths of the plane, the Deep Ethereal, are a region of swirling mists and colorful fogs.
The Astral Plane is the realm of thought and dream, where visitors travel as disembodied souls to reach the planes of the divine and demonic. It is a great, silvery sea, the same above and below, with swirling wisps of white and gray streaking among motes of light resembling distant stars. Erratic whirlpools of color flicker in midair like spinning coins. Occasional bits of solid matter can be found here, but most of the Astral Plane is an endless, open domain.
The Inner Planes
The Inner Planes surround and enfold the Material Plane and its echoes, providing the raw elemental substance from which all the worlds were made. The four Elemental Planes - Air, Earth, Fire, and Water - form a ring around the Material Plane, suspended within the churning Elemental Chaos.
The Outer Planes
If the Inner Planes are the raw matter and energy that makes up the multiverse, the Outer Planes are the direction, thought and purpose for such construction. Accordingly, many sages refer to the Outer Planes as divine planes, spiritual planes, or godly planes, for the Outer Planes are best known as the homes of deities.
The Energy Planes
Like a dome above the other planes, the Positive Plane is the source of radiant energy and the raw life force that suffuses all living beings, from the puny to the sublime. Its dark reflection is the Negative Plane, the source of necrotic energy that destroys the living and animates the undead.
