Spiralspace

Spiralspace is the term used to describe the Atavian System and Urz's surrounding environs within the greater Prime Material Plane.
== The Atavian System ==
The Atavian System is built on a heliocentric model, with the star known as Atavus at the center of the crystal sphere.
=== Atavus, the Sun ===
This star burns hot and, due to its vibrant nature, might be mistaken for a star that is much older than it is. It is the largest fire body of Spiralspace and is a conduit of Radiance as well, located at the center of the system. It radiates a comfortable amount of warmth throughout the entire sphere. Sages believe the duality of the star, being an ordered center to the structure of the system and a chaotic source of solar flares is a marker of it being the purest form of the god Atavius.
=== Stilbon, Birthplace of Death ===
The world of Stilbon is a small planet that is the closest of the systems five wanderers. It was the birthplace of mortality in the sphere at a city called Kasmacalau. The world is inhabited now by a number of subterranean cultures as the surface of the world is a wasteland devoid life and the winds of magic, blasted by the heat of Atavus. The peoples that live within Stilbon can call up magic from wellsprings within the world's hollow core.
=== Urz, the Prime Material ===
==== Stacia ====
==== Umbra ====
=== Lagren ===
=== Zuhel ===
=== Charapos ===
=== Additional Astronomical Bodies ===
The Bright Star
=== Chaos Stars ===
Within the crystal sphere are a number of smaller stars that radiate with far realm infestation. These stars have irregular orbits around Atavus and this sometimes leads them to exiting the crystal sphere, moving about the Shattered Planes, and re-entering into the Atavian System. A number of Great Old Ones call such stars their homes.

== The Crystal Sphere ==
The original Crystal Gate, also called the "sphere wall" or "shell", of Spiralspace was made whole by divine magic, more like rough crystal than the perfectly smooth sphere of modernity. During the formation of all that is within the sphere at a moment in history sages agree is called the "Song of Creation", the Gate shattered and parts of it fell into Spiralspace while other parts lingered and formed the initial medium for the Shattered Planes. In its place was the sphere, with a radius of 1.8 billion miles (2.89 billion km). Due to the strong arcanum gravitum of Atavus and the balanced arcane inner flow within the sphere, the planes within follow an ordered dance about the star.
== The Shattered Planes ==
Around the whole of Spiralspace outside of the Crystal Shell is a wake of spatial and temporal debris. These pieces themselves are worlds, ruined and broken by the intense destruction at the Edge of Creation. 
=== Constellations ===
The combination of the Shattered Plane structures and stars encircling the sphere as well as the stars within the sphere and the far off planes and stars in the phlogiston form the constellations. Spiralspace has a great number of constellations as viewed in the night sky.

== History ==
Though the birth of a crystal sphere is a rare event that draws divine eyes, the closeness of Spiralspace's formation to the Edge of Creation lead the planes within to be subjected to only the Warring Triumvirate, a triad of deities that would go on to experiment with the space themselves and eventually be barred from interfering directly with mortals and the Material. The strength of the Crystal Gate in Urz's formation is believed to be due to the power of these three divinities and the sphere's strong arcanum gravitum is believed to be due to the raw stuff of creation the worlds and the sphere were shaped from.
