Gloamnull, the city of rain, is one of the cities being settled by the genasi. It is constantly subjected to the rain, and the earthmote it rests on is constantly overflowing with the rain. While the genasi appear kind to weary travelers, the inhabitants hold a dark secret close. Many among them worship Dagon, an Elder Evil who saved them from the near-constant attacks from archons and giants. In exchange, they give sacrifices to Dagon, killing the unfaithful among them or travelers if they happen to be there at the wrong time.

Filling the rivers and caverns that dot their earthmote are strange fish with tentacles around their mouths, presumably sent by Dagon. The inhabitants rely on those strange fish for their main source of food and utilize trade to help supplement their meals. The settlement is slowly growing, and more escaped genasi arrive daily.

Pillars of Creation

Holding up the Elemental Chaos are the massive Pillars of Creation, each formed from different elements. They are said to stretch from the very bottom of the Elemental Chaos to the very top of it, holding it all together. Though the fact that the plane is infinite in size has done very little to discourage travelers from trying to reach the very top or bottom of the pillars, and there have never been any reports that someone has succeeded in the task. The pillars all range in thickness from a few hundred yards around to miles wide, and each have elemental creatures that prowl across their surfaces.

There are only a handful of known pillars, like the Obelisk of Ice which is made of pure ice with runes etched across its surfaces, the Raging Storm which is made of cloudlike matter stacked on itself and storm creature crawl all around the surface, or the Torrent of Magma which has a flowing surface of magma and air while islands float around it.

Factions & People

Elementals

While most adventurers would assume that the main inhabitants of the Elemental Chaos would be the elementals, many prefer to exist in their native planes where they aren’t exposed to the different elements that they aren't made up of. The elementals that do exist in the chaos take on the form of a wide variety of elements and maybe the only one of their kind. There have been rare sightings of strange and new elementals in the chaos, though none have been able to capture them or study them in great detail.

Archons

Archons are elementals that have been put through a process where they are forge and bound into armor using the powerful foundries that the primordials created during the Dawn War. They are forced to serve and are only interested in combat. They hate all celestials with a burning passion and care little for their own life if it means they could kill one. It is said that there are great armies of archons preparing for their primordial commander, eagerly awaiting the day that their master is free and they can strike out at the divine powers.

Genasi

The genasi are typically born between elementals and the inhabitants of the Material World, though they may have human parents who were just exposed to the Elemental Chaos and were twisted while in the womb. The genasi are not quite suited for living in the Elemental Chaos, though they have little choice as the inhabitants of the Inner Planes would want to enslave them and, even on the Material World, they are treated with distrust and sometimes violence.

They do what they have to do in the chaos, and have begun setting up settlements, hoping that they can create genasi cities where they are free to live with their own kind.

Primordials

During the Dawn War, the primordials rose up against the divine host. The gods wanted to protect the Material World from the destruction of the primordials who see the static Material World as a slight against them. By the end of the war, primordials and gods alike were killed in the wake, though the divine were able to ultimately win. They imprisoned several of the primordials and cast their prisons into the deep reaches of the Elemental Chaos, they hope for good.

As time passes by, the primordials are growing their power and, while many of them are imprisoned, a handful was able to escape that fate and they still rage across the Elemental Chaos slowly growing their armies for the day the others escape their prisons.

Balcoth, the Groaning King

Balcoth is one of the imprisoned primordials, though he experiences more freedom than several of the others. His body freely roams through the Elemental Chaos, though it is in constant search for its head, which is locked away in a prison on the Material World. The body blindly wanders the chaos, hoping to find a way to save itself from the eternal torture the gods are putting it through.

Titans

The titans of the primordials, also known as archomentals, are often mistaken for the primordials. They were created to be the generals and mighty champions of the primordials, and continue on the mission to destroy the Material World. The likes of Yan-C-Bin, the evil prince of air, and Olhydra, the evil prince of water, are using their influence, even while imprisoned, to create cults in their name and to cause devastation where they can.
