Fallen World

After the Exarchs comitted the ultimate act of hubris, to usurp the control of the Realms Supernal, and the Celestial Ladder was shattered during the climatic battle of those who supported their claim and those who opposed it and would later from the Oracles, the Tapestry was shaken to its core and this allowed the Abyss to stretch itself between the higher truths and the material realms, thus separating it from the truth of magic and bringing the Lie into being. All that remained from the world was a fallen remnant of what it has once been.

Geography
Within the Tapestry, the Fallen World lies between the higher truths of the Realms Supernal and the gnawing void of the Lower Depths.

The Fallen World is further divided into two parts: The Realm Material, that is accessed everyday and forms the reality most Sleepers will ever know, and the Realms Invisible, who have clearly supernatural traces left but are barred from the higher truths through the Abyss.
