Crystal sphere article created
A '''crystal sphere''' is an object of great size that surrounds an entire [[planetary system]] and forms a boundry that separates [[wildspace]] from [[phlogiston, the|the phlogiston]].<ref name="CoAS">[[AD%26D_Adventures_in_Space#Concordance_of_Arcane_Space|''Concordance of Arcane Space'']] pages 9-10</ref>
The size of crystal spheres is related to the size of the planetery system within them. As the name 'crystal sphere' implies, the objects are spherical.<ref name="CoAS">[[AD%26D_Adventures_in_Space#Concordance_of_Arcane_Space|''Concordance of Arcane Space'']] pages 9-10</ref>
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.<ref name="CoAS">[[AD%26D_Adventures_in_Space#Concordance_of_Arcane_Space|''Concordance of Arcane Space'']] pages 9-10</ref>
Crystal spheres are also known as crystal shells.<ref name="CoAS">[[AD%26D_Adventures_in_Space#Concordance_of_Arcane_Space|''Concordance of Arcane Space'']] pages 9-10</ref>
==Travel Through a Crystal Sphere==
Only a few methods are known to allow travel from one side of a crystal sphere to the other side.<ref name="CoAS">[[AD%26D_Adventures_in_Space#Concordance_of_Arcane_Space|''Concordance of Arcane Space'']] pages 9-10</ref>
===[[Teleport]] or [[Dimension Door]] Spells===
These spells (or magical devices that duplicate them) allow spellcasters to jump from one side of the sphere to the other without phsically crossing the sphere.
===[[Phase Door]] Spell===
This spell (or a magical item that duplicates it) makes part of the crystal sphere immaterial and allows a [[spelljamming ship]] to pass through.
===Naturally Occuring Portals===
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.
===[[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 Radience]] or the [[Plane of Fire]]. Flying a ship into one of those stars would be fatal.
===[[Spelljammer, The|''The Spelljammer'']] and Creatures Like Space Dragons===
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.
===The [[Create Portal]] Spell===
This spell duplicates the natural ability of ''The Spelljammer'' and space dragons, but the portals created by this spell has a much shorter duration. Portals created via this spell last no longer than 120 minutes.
==Individual Crystal Spheres==
===Size of Individual Crystal Spheres===
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.<ref name="CoAS">[[AD%26D_Adventures_in_Space#Concordance_of_Arcane_Space|''Concordance of Arcane Space'']] pages 9-10</ref> 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 body|celestial bodies]] are [[additional astronomicals]] rather than true planets.<ref name="SJR6">[[SJR6 Greyspace|''SJR6 Greyspace'']] page 3</ref>
