Ha'ther

*This article describes the celestial body and physical location of Ha’ther.  For the properties of the matterspace continuum, see the article for the Aether.*

Ha’ther, in the form of the Aether, can (and often does) act under a form of consciousness.  Because of this, Ha’ther is often considered a deity among mortal religions. In the Hymn of the Cosmos, Ha’ther is represented as a serpent of immeasurable size which encircles and supports the many realms of the universe.  This image is sometimes crossed with that of Ouroboros.

The hymnal also counts Ha’ther among the Elder Gods, a notion which has been popularly accepted.

## Geography

The universe of Ha’ther is largely composed of two types of matterspace: the spatial planes and the unworked Aether.  The former features a definite separation of spatial and material Aetherial characteristics, while the latter is a non-uniform, chaotic mixing of these aspects.

Flora, fauna and sentient beings are known to reside in both of these locations, though the majority tend to favor the planes.

### The Aether

Often described as a vast, chaotic sea, the non-planar Aether displays a mix of characteristics of all five elements and dimensions.  Due to the inherent navigational challenges this poses to planar beings, directional descriptions are often based

### Spatial Planes

*Main article: Spatial Plane*

A vast array of spatial planes have been hewn from the Aether.  The majority of these can be classified as one of three types: Aetherial planes, elemental planes and material planes.

#### Aetherial Planes

*Main article: Aetherial Plane*

Aetherial planes are the simplest of design and feature the smallest differentiation between material and spatial aspects.  To planar beings, matter in Aetherial planes may appear diverse, but this mostly comes from varying orientations of the Aether.  Because of this, Aetherial planes have a much less rigid form than other types of planes.

These planes are most famously occupied by various celestial subraces, including planar avatars from non-Aetherial planes (though this is less common).

Known Aetherial planes:

* The Abyss
* Bek-Ten-Hak

#### Elemental Planes

*Main article: Elemental Plane*

Elemental Planes are similar in construction to Aetherial planes but have a uniformity of material orientation.  There are only five true Elemental planes, corresponding with the quintessential elements.  In the creation of the material planes, miniature regions of planar overlap (known as “micro-gates”) were used to compose the non-native matter characteristic to these planes.  This method causes an exchange of material, which has allowed the elemental planes to have a degree of apparent (though not true) non-uniformity, in the form of terrain and so on.

Known elemental planes:

* Djot-ten, the Elemental Plane of Earth
* Ha’ala, the Elemental Plane of Water
* Set Ephra, the Elemental Plane of Air
* Sohep, the Elemental Plane of Fire
* Sot, the Elemental Plane of Adamant

##### Para-Elemental Planes

*Main article: Para-Elemental Plane*
A less-common type of plane exists which mimics the physical form of an elemental plane.  These planes, known as the para-elemental planes, represent more abstract (multi-elemental) characteristics of the Aether in complete uniformity and were also used in construction of the material planes.

Known para-elemental planes:

* the plane of Time (name this)

#### Material Planes

*Main article: Material Plane*

Material planes account for the majority of the population of Ha’ther and are the most common type of plane.  Though they are somewhat more complicated in structure than their Aetherial or elemental counterparts, material planes offer the most diversity of matter and have been used as inspiration in the construction of some Aetherial planes.

Known material planes:

* Aaphobim, the child-plane of the god of the same name.  Though many planes exist, this (along with Ysenna’s material plane) is considered to be the center of the cosmological structure.
* Ysenna, the child-plane of the goddess of the same name.
