Elemental Plane of Fire

The Elemental Plane of Fire was an Inner Plane or Elemental Plane of the Great Wheel cosmology and the World Tree cosmology models. After the Spellplague, the Elemental Plane of Fire collapsed into the Elemental Chaos, mixing with all the other Inner Planes. Fire is one of the four elements and two energies that make up the known universe and, more than any other element, has fascinated sentient beings since the beginning of time. The flickering of a candle, the spark of a flint and steel, or the dying embers of a campfire, all have the potential to grow and engulf the world in flame&mdash;can a drop of water, a breath of air, or a mote of dust do the same?

Cosmology
According to the Great Wheel cosmology model, the Elemental Plane of Fire could be reached via the Ethereal Plane, an adjacent elemental plane, or by an elemental vortex. If traveling through the Deep Ethereal, a red curtain of vaporous color indicated the boundary of the Plane of Fire's Border Ethereal region. Once in the Border Ethereal, a traveler could observe the Plane of Fire and be detected by its denizens. Using the spherical model, this plane was adjacent to the para-elemental planes of Smoke and Magma and the quasi-elemental planes of Radiance and Ash. Elemental vortices could occur wherever a high concentration or nearly pure form of an element was found, and could be temporary or permanent. Vortices to the Plane of Fire could often be found in pools of molten lava or the upwelling of magma in active volcanoes. Temporary gates could be created by the plane shift spell or the abilities of high level druids.

As described by the World Tree cosmology model, the Astral Plane connected all planes with the Prime Material Plane and the Ethereal Plane was only used for journeying between locations on the Prime. The Elemental Plane of Fire was not connected or coterminous with any other elemental plane. The spell astral projection could be used to reach the Plane of Water via a fire opal color pool. (See Notes.) Additionally, the gate and plane shift spells could be used to open a temporary portal to this plane.

Description
"It is a plane continually ablaze. It smells of burning flesh and ashen dreams. It is flame incarnate."

Arriving on the Plane of Fire was like stepping into the flaming maw of an ancient red dragon, if you didn't have protection or immunity from temperatures high enough to melt stone then death was swift. The following discussion assumes a visitor and all her clothing and gear had this capability and either did not need to breathe or could compensate for a superheated, often toxic atmosphere that could immolate you from the inside (think cloudkill plus incendiary cloud). In general, the more fluid the elemental fire, the hotter it was and the more damage it did to unprotected material.

Unlike the other three elemental planes, the Plane of Fire had normal gravity and a landscape, although most of the "ground" was made primarily of loosely packed elemental fire and felt like walking in a swamp of hot coals. The rivers and oceans were filled with a more liquid version of the same stuff and swimming worked normally as a mode of transportation. Non-native flying creatures found the atmosphere thin and therefore did not have their usual speed or maneuverability. Visibility was hampered by the smoke coming off the flames engulfing but not consuming nearly every solid, liquid, or gas (and creature) on the plane. What you could see was usually distorted by heat ripples. Geographic features such as hills, mountains, and cliffs did not have a geologic lifespan because even the more solid areas slowly moved like a subterranean magma flow as seen on the Prime Material Plane. Permanent physical structures were very rare.

If the Plane of Fire had weather, it was of course hot and deadly. Rains of hot ash moved about like thunderstorms, threatening those on or near the ground with hot embers and blinding ash. Those in the air had to watch out for clouds of superheated steam blowing around and condensing scalding water on exposed surfaces. The water quickly evaporated and the cycle began anew. Easier to avoid but just as deadly were the rivers of magma and "firefalls". Matter from other planes either evaporated, burned to ash, or melted into magma. Magma mixed with elemental fire formed a rapidly moving, incredibly hot slurry that coursed around the terrain and occasionally cascaded over a cliff edge to create a firefall, often manifesting an elemental vortex in the spectacular display.

The City of Brass is populated by the Grand Sultan and is considered by many efreet to be their home and capital. The most famous location in the Elemental Plane of Fire, it rests at the plane's heart sheltering all who enter from the harsh surrounding nature.

The Elemental Foundation of Fire
An important feature of the plane was the Elemental Foundation of Fire, one of four magical switches (one in each of the four elemental planes) that when activated caused the Onyx Tower to rise on the Prime Material Plane.

Inhabitants
Despite being one of the most hostile of the Inner Planes, the Foundation of Fire is also one of the most vibrant. A number of natives reside on the plane, including fire elementals, who are actually sentient pieces of the plane itself, a number of outsiders and other fire-using creatures. Efreet, azers, and salamanders have more organized societies than elementals, often inhabiting large settlements. Outsiders tend to be a bit more hospitable to foreigners, while several communities go out of their way to accommodate travelers. Other fire-using creatures call the Plane of Fire home as well, residing near vortices that lead to their home planes. Creatures that are immune to fire, such as devils, may also be found at such locations. There is regular traffic in information, goods, and prisoners between the City of Brass and the Nine Hells.

The native language of most inhabitants of the Elemental Plane of Fire is Ignan, a sharp, hissing and clicking language. Those natives who deal with other planes may speak in other tongues as well, with Infernal and Common being among the most prevalent.
