Fyrtorria

= The Four-Layered Reality = The Four-Layered Reality  is a cosmic model comprised of 4 concentrical universes - one inside another - that describes reality as the Alarians had come to understand it. Outside the 4 interwoven universes is believed to be an endless void of cosmic emptiness called "The Great Black".

These four universes are named "Orrias", and are so tightly-interwoven they cannot exist one without the other. The Orrias are separated by a thin layer of space called "the Shroud" (or  Shääj, in the Alarian language, Æurlek). According to Alarian teachings, the Four-Layered Reality, along with the Great Black, are part of a colossal, magnificent and well-balanced cosmological organism called Fyrtorria.

Fyrtorria is comprised of  Lorria, Ælorria, Tylorria  and  Nilorria, each separated by differently-dense versions of the Shroud.
