==Topography & Environments==
===Subterranean Realms===
The Time Flow from Shadow to Shadow within the Subterra System is consistent and at a rate of 10 to 1 with Amber.  The Shadow of Subterra is actually a limited Shadow System of nearly 1,000 Shadows all stemming from the Squiggle at it heart and the Thirteen Shadows considered to be the Core of the Subterra Shadow System.  Twelve of the thirteen ‘core shadows’ are exclusively subterranean; if there is a ‘surface’ on these worlds they have never been found.  Clean breathable air is abundant and only the most remote pockets of caverns might contain ‘stale air’ or ‘dead air’.  The extensive interconnected caverns and tunnels that honeycomb Subterra come in all shapes, sizes, and an extensive variety of rock types.  The caverns of Subterra can include glowing fungus, glowing crystals, precious metals, precious gemstones, a wide variety of edible and inedible fungi, molds and rarely roots, a multitude of creatures adapted to subterranean life, and a wide variety of intelligent, subterranean beings with cultures and civilizations and politics and wars.

====Food====
Food sources range from fungi and molds to living creatures, some domesticated for food, some ‘wild’ and sometimes other denizens of Subterra.
Those Shadows with surface worlds also have a variety of edible plants and animals, pretty standard fare.

====Lighting====
Lighting is usually glowing fungus, glowing and sometimes light emitting crystals or crystal formations (sometimes quite enormous).  There is no day/night cycle in Subterra except that which is commonly accepted in large settlements; most of Subterra is 24/7, so to speak, with people sleeping at different times depending upon their location, employer or preference.

===Surface Realms===
The rest of the Subterra Shadow System is filled with Shadows that all contain similarly massive interconnected cavern systems, most all of which have inhabitants and complex civilizations, but they also contain surface worlds, filled with varying degrees of inhabitants, cultures and civilizations.
