Since the beginning, mortal’s greatest interrogative was the origin of all. Eventually, the source of life was traced to the presence of three separate worlds. These three worlds presided over three different sources of arcane power, inherent to the world themselves.
The Sempiternal (Sidir)
Also known as the Outer World or Sidereal Plane, this is a dwelling for supernal beings. A boundless space, filled with stars and celestial bodies. Jagged with lights and nothingness. In this infinite layer of reality, every entity pays close attention to the vicissitudes of life created on the Material Plane.
The Earthly World (Faerun)
Mortals also call it the Material Plane. This is the known world, where all living beings and mortal species dwell. The energy that rules over this world, as it rules over all life, comes from the Primes: ancient and omnipresent beings of sidereal origin.
The Dark Mirror (Enfaerun)
This spectral reality harbors nothing but darkness and death and it is intertwined in a dualism with the Material Plane. Its name – Enfaerun – means underworld, or abyss, in the Prime Tongue. Anything considered negative, disruptive, obscure, or concealed from light belongs in this dimension. Here resides the mirrored images of the Primes, known as the Death Echoes. These dark entities enslave the souls of the wicked, who are drawn to them in death, and defile any life form that falls into their influence.
No one knows what fate awaits those who die in Faerun. Most believe in, and pray for, becoming part of the world and of the Primes’ conscience, while others long for the cosmos. One belief, however, is shared by everyone: those who die in unholiness, dishonor or with a curse upon them are destined to spend eternity in Enfaerun.
