Far Realm

The Far Realm is a plane of madness situated very far from the planes of the standard cosmology. This maddening realm is feared for its power to twist unfortunate visitors into gruesome monsters, and it is from here that aberrations come.

Geography and Characteristics
The Far Realm is composed of an infinite number of layers, but unlike those of many Outer Planes, the layers of the Far Realm are thin. A Far Realm layer can range from an inch to a mile thick. On average, each layer is separated from the other by about ten feet. Travelers are able to see through many layers simultaneously. Usually twenty layers can be seen at once, each one blurrier than the last. The layers are also highly morphic. On the whim of the alien entities that drift through them, the layers continually evaporate, divide, spawn, and breathe. Changes in the elemental and energy traits of the layers continuously occur, creating the Far Realm equivalent of a storm. These changes can be seen from far off, moving from layer to layer as a storm moves across the face of a normal world.

Features and creatures of the Far Realm are multidimensional and can exist on more than one layer simultaneously. The layers of the Far Realm are like a stack of translucent parchment, and the multilayered creatures are like a single dot marked upon each parchment, seemingly coalescing into a three-dimensional object. The translucent layers seem to fade away on either side and are pierced with free-floating rivers of milk-white liquid that sometimes flow along a layer's edge for a few feet before plunging into the next. Strange blue globes rain down from unseen heights, bursting when they strike an object and releasing ticks the size of horses that immediately scuttle off in search of blood. Gelatinous worms wriggle from layer to layer through tentacled vegetation encrusted with orange moss, all of which is suspended above an amoebic sea. Vast multilayered shapes drift through the layers, the smallest being the size of a city.

Gravity and time do not exist in the Far Realm. The entities of the Far Realm float around in dark nothingness. The air is syrupy thick, and strong strokes are needed to swim through it. Another type of movement that is allowed in the Far Realm is passage between layers, which requires only a thought. Non-natives to the Far Realm can only exist on one layer at a time, but large Far Realm entities often exist in several layers simultaneously.

Inhabitants
The Far Realm has many different inhabitants, many of them sentient. Some resemble mammals, while others are insectoid. Some are even as powerful as deities (whether they are sentient or not may be difficult to assess, although Ghaunadaur may originally have been one of these). When confronted with beings from the Material Plane, the Inner Planes, or the Outer Planes, Far Realm entities often take the form of creatures familiar to the viewer, although they are usually horribly disfigured and grotesque.

The simplest natives of the Far Realm are the pseudonatural creatures that roam the different layers, occupied with unguessable errands. They dwell beyond time itself and the regular planes of existence, living forever in a state of seeming insanity. When summoned to the Material Plane (which is a very rare and extremely difficult task), they often emulate and take the shape of familiar creatures, although they are always more gruesome than their earthly counterparts. Sometimes, however, they appear in a form more closely related to their origins, usually a mass of writhing tentacles, although more terrible forms are always possible.

The next step up in the bizarre evolution of the Far Realm inhabitants would be the Kaorti. Born from an exploring order of Imaskari wizards known as the Quin, the Kaorti eventually returned to the Material Plane, which they could no longer inhabit. The first of them died out, but the second wave came in suits of protective resin, and used the same secretion to form protective cysts to live in. They now seek to conquer the Material Plane and turn it into a new Far Realm. They have created several creatures for this task: the flying mount creatures known as Skybleeders, the living siege engines known as the Rukanyr, the Urquirshes which provide endless quantities of protective resin, and the deadly Thruocks, egg-implanting ravagers.

The Lords over the Far Realm are the Uvuudaum. These are horrifying creatures that have two arms where you would expect to find them on a human. However, the similarities end there. The lower body has six arms instead of legs splayed spider-like below it. Loose clothing drapes its grotesque legs. The real horror is the tail-like appendage replacing what would be the head on a normal creature. At the very end of the appendage is an iron hard spike.

Travel
Mortal travelers to the Far Realm would usually be subject to insanity. All sorts of horrifying changes can occur to them, such as eyes sprouting from their palms. They can also relive a hundred warped memories simultaneously.

There are no known portals to the Far Realm. Ancient elves once pierced the boundary of eons by creating a portal to the Far Realm, called the "Vast Gate." However, their civilization imploded in bloody terror, and since then, the portal's location remains unknown to most, though it lies hidden within Firestorm Peak (this does not seem to be on Toril). , There are other methods for reaching the Far Realm, though, such as traveling to the beginning or end of time or finding the true Dreamheart (the heart of the Region of Dreams) past the Portal of Sleep.
