Solarion - The Sphere of Light

This sphere of blinding radiance is located in the center of Erhad. It is composed of the souls of all the virtuous dead. Souls within the sphere have no physical substance, but may travel to planets or are sometimes allowed to subsume into celestials.

Kal'Nuega - The Sphere of Darkness

This globe of absolute darkness, which from any perspective resembles more of a pit than a sphere, resides at the heart of Nuegalon and is the culmination of all the souls of the wicked dead. Though souls within the sphere are incorporeal, they can be taken into hellscapes or given substance by powerful fiends for purposes of labor within Nuegalon. Sometimes souls are commanded to amalgamate into fiendish beings such as demons and devils.

Moons

The moons of Heroshi are said to be droplets from Cura's cup of mercy. These luminescent spheres, which vary in size and color, are spheroid in shape when still.  A moon in motion, however, somewhat resembles a whale composed of sea water. The Lunar celestials are their guardians and caretakers. They cause them to appear in Heroshi's sky at night, moving them around and adjusting their brightness as needed to provide signs for mortals to interpret. Curan priestesses often provide moon readings for the town they reside in.

Planets

In Erhad there are spheres that resemble miniature worlds. They range in size from that of an inn to an entire city ward. One may enter those realms through the planets. These planets are generated by the Sphere of Light and serve as spirit homes. Petitioners of Erhad are given a tangible form in these places.

Hellscapes

Nuegalon has natural fissures which emanate eldritch vapors. Passing through one will lead travellers into new worlds of horror in realms spawned by the Sphere of Darkness. Petitioners within hellscapes are given tangible form for the purposes of subjecting their bodies to torment.
