Aether

The Aether (also known as the “seas of creation” or the “Aetherial Sea”) acts simultaneously as the location, material and namesake of the universe of Ha’ther. Being an invention of the Elder Gods Aaphobim and Ysenna, the Aether is the unification of dimensionality and substance, otherwise known as the matterspace continuum.

It is both within and from the Aether that the Planes are made.

In form, the Aether resembles an infinite, dimensionally-unstable sea of spectral coloring.

Due to its religious significance (especially in the Hymn of the Cosmos) and due to its encompassing of all sentience, the Aether is often anthropomorphized. In the Hymnal, the Aether appears as a female deity named Ha'ther.

Navigation
Wayfinding in the Aetherial Sea is an inherently difficult feat.

Most attempt to avoid Aetherial navigation; despite this, vessels can and have been built for extra-planar travel. The most popular of these is the aethership.

Inhabitants
Although the vast majority of life in Ha’ther is both born and bound to the planes, extra-Planar life is not unheard of.

Those familiar with Aetherial lifeforms often liken them to those of deep-dwelling waterborne species.
