==Thirteenth: The Rock, a Primal Realm==
Though it is called 'Thirteenth', the Thirteenth Realm of the Core Realms is actually the First Realm... or more precisely the Primal Realm on which all the other Realms/Worlds/Shadows are based upon, at least in some fashion. It truly unique amongst all the nearly 1,000 Realms/Shadows of the Subterra System.  
*First, it is precisely in the center of the Subterra System. 
*Second, it is an almost perfectly spherical ‘rock’ 10 miles in diameter which has a ‘surface’ and ‘space’ of sorts but no stars or a sun.  
*Third, though it does have breathable air throughout the Realm, air that never gets stale or dead, it only extends 30' out from its 'surface' on its 'Surface World'.  
*Forth, the entire Realm/World seems to be dimly lit ‘everywhere’ with no direct light source present.  
*Fifth, though this Shadow has normal (Earth) gravity just like all of Subterra, it comes from the ‘rock beneath your feet’, not the center of the sphere, thus allowing one to traverse any surface at any angle.  
*And lastly, but most importantly, it contains a Squiggle, the only assayable Inscription in all of Subterra.  

The ‘Rock’ is honeycombed and criss-crossed with tunnels, caverns and columns/bridges of rock, all of which seem to intersect each other at all angles. In the Heart of the Rock, the ‘center of the sphere’, there is a cavern of titanic proportions, about 1 mile across in all directions, that is made of a white crystal and filled with columns/bridges, made of the same white crystal, that criss-cross and intersect at all angles, spanning the length, breadth and depth of the titanic crystal cavern; it is called ‘The Geode’.  And in the center of it, where the crystal columns/bridges intersect the most tightly is where one can find the Squiggle.

The Squiggle is a small (compared to the Pattern) three dimensional inscription of power, that can be negotiated from either end.  It glows dimly and shifts color every 30 seconds or so, running through the entire spectrum of colors (more than the standard seven in a rainbow), but not in any particular order or pattern.  The light given off by the Squiggle does not travel far, barely enough for it to be seen while negotiating its three dimensional lines and angles, thus making it very difficult to find if one does not already know where it is.  The Squiggle is aptly named ‘The Gem’ due to its ‘shape’ when looked at ‘from the outside’ (or the inside); it somewhat resembles lines partially tracing the inside of a faceted gem.
