A crystal sphere, also known as a crystal shell, is an object of great size that surrounds an entire planetary system and forms a boundary that separates wildspace from the phlogiston.[1]

The size of crystal spheres is related to the size of the planetary system within them. As the name 'crystal sphere' implies, the objects are spherical.[1]

Although they are solid, crystal spheres have no gravity and no atmosphere. The material crystal spheres are made of is a unbreakable dark ceramic material. No magic is powerful enough to damage crystal spheres.[1]

Travel through a crystal sphere[edit]

Only a few methods are known to allow travel from one side of a crystal sphere to the other side.[1]

Teleport or Dimension Door spells[edit]

Main article: Teleport

These spells (or magical devices that duplicate them) allow spellcasters to jump from one side of the sphere to the other without physically crossing the sphere.[1]

Phase Door spell[edit]

Main article: Phase Door

This spell (or a magical item that duplicates it) makes part of the crystal sphere immaterial and allows a spelljamming ship to pass through.[1]

Naturally occurring portals[edit]

Main article: Crystal sphere portal

Most crystal spheres have natural portals that pierce the shell at various locations. These portals usually and vanish at random times and are located in random places. Looking for these portals can take a long time.[1]

Stars[edit]

Main article: Stars

In some crystal spheres, stars are located on the inside of the crystal shell. A few of these stars are themselves also natural portals through the crystal sphere. A spelljamming ship diving into the heart of the star would pass through the shell and appear in the phlogiston. However, a high number of stars are portals to the Plane of Radiance or the Plane of Fire. Flying a ship into one of those stars would be fatal.[1]

The Spelljammer and creatures like space dragons[edit]

Main article: The Spelljammer

The legendary ship, called The Spelljammer, and some large space creatures, like space dragons, seem to have an innate ability to create portals similar to the natural portals. These portals close slowly over time, so ships can sometimes use them.[1]

The Create Portal spell[edit]

Main article: Create Portal

This spell duplicates the natural ability of The Spelljammer and space dragons, but the portals created by this spell have a much shorter duration. Portals created via this spell last no longer than 120 minutes.[1]

Individual crystal spheres[edit]

Size of individual crystal spheres[edit]

The size of crystal spheres is usually determined by the size of the planetary system within them. Each sphere usually is usually twice the diameter as the outermost planet within the crystal sphere, but spheres can be larger than this.[1] There are often astronomical objects that defy this 'double diameter' rule and orbit outside the outermost planet. Sages who support the 'double diameter' rule usually argue that these celestial bodies are additional astronomicals rather than true planets.[2]

Nested spheres[edit]

It is possible for a crystal sphere to contain another crystal sphere, or a series of smaller and smaller crystal spheres.[3]

Main theories[edit]

There are six main theories about the origin of the crystal spheres.

The gods created the shells and the flow[edit]

The gods created the spheres and the Phlogiston in order to divide up the universe. The gods split the universe into chaos (the flow) and order (the spheres). They then divided up the individual spheres among themselves in order to test law against chaos and good against evil.[4]

The gods have their own gods[edit]

These gods-of-gods created the universe, and then placed the gods into the universe. This theory gained more popularity in Realmspace in recent times.[4]

The Phlogiston is a naturally occurring object[edit]

The Phlogiston was there before the gods. The gods built the crystal spheres to settle and domesticate the flow. The spheres are like cities built along a stream and eventually they will grow and join together. When this happens the Phlogiston will cease to exist.[4]

The gods fear the flow[edit]

The gods fear the Phlogiston and built the spheres to keep it out.[4]

The gods fear men and other sentient beings[edit]

The gods fear humans and other sentient creatures and built the crystal spheres to keep them in.[4]

The Phlogiston and the shells are naturally occurring[edit]

Someone or something created the entire universe and the gods moved in and took over. There is a secondary implication, that the gods have lied about creating the universe to deceive mortals.[4]
