Realms can be described as pockets of reality, fitted onto a circular wheel. There are two wheels, one for the overworld’s realms of life, and another for the underworld’s realms of the afterlife. Realms on each wheel fit snuggly neighboring each other in pie-slice slots, but never collide thanks to the fabric of reality. Each wheel's pace dictates the speed at which time passes in all realms of the overworld or underworld. The deities can technically change a wheel’s pace, but doing so would cause extraordinary chaos. The overworld wheel lies above the underworld wheel, with Faia in between as an exception to typical realms. The empty space between and outside realms is referred to as ‘void’ by the deities, and unknown to mortals.

To prevent blocking spirits’ passage to the afterlife from the overworld wheel, there is a large hole in the center of Faia. The deities have separated this hole by surrounding it with an enormous circular mountain range, too high for even airships to cross. If a Faian were to cross it, they would simply see a lagoon in the center of the mountains. They might be able to see the spirit flow, but this would require said Faian to be experienced in magic, and for the spirit flow to be unusually busy. If a Faian were to climb down from the mountains and approach the lagoon, they would be met by an invisible wall. This wall is what prevents Faians from falling into the void. It is what deities call the fabric of reality.

The fabric of reality is invisible to the mortal eye, and transparent in deities’ eyes. It defines the physical boundaries of realms. In other words, it defines the end of the world. Faia is the only flat realm in the universe, and if any Faian were to reach the edge, this fabric would prevent them from falling off. Instead, they would meet that same invisible wall around the hole. To make the borders of realms less glaringly obvious to its inhabitants, the deities always set illusions on the interior fabric.

The deities can manipulate the fabric of realities in several ways to alter, create, and destroy realms. For example to create a new realm, the deities will stretch the fabric to make a new pocket, where they insert the new world. To destroy a realm, the deities will simply tighten the fabric around said realm to crush it. If you were an inhabitant in a realm actively being destroyed, it would seem as if the sky was closing in on the ground, and the ground was closing in on itself. Certainly not an enjoyable experience. 

Each overworld realm directly connects to a parallel afterlife realm through a thin tunnel, which passes through the center of Faia. Afterlife realms are not identical to their counterpart, but often contain similar landmarks and biomes to provide spirits with a sense of home. Spirits are immediately transported to their afterlife realm upon death, where they can live in solitude, or even seek out their loved ones. Afterlife realms are designed to prepare spirits for their true death. When a spirit is ready to move on, it travels to the Voidling’s Well.

The way to reach the Voidling’s Well in each afterlife realm is different, but always ends in a door. To a spirit who has not wrapped up all loose ends in their afterlife, opening the door will do nothing. The door only allows passage to those who are satisfied and truly ready to end their afterlife. Once a spirit steps through the door, there is no turning back.

The Voidling’s Well is a small realm located in the center of the underworld wheel. It is an exception to typical realms as well; the fabric of reality does not cover the entire realm. The “entire realm” is only a dozen square feet in width; it is very small. The sky is a gradient of colors, and the ground consists of shimmery sand. In the center of the realm, or more realistically, the room with invisible walls, is a well guarded by the Voidling.

The Voidling is an immortal being appointed to guarding the well, and has been there since the beginning. Their job is to make sure each spirit present is fully ready to move on, just in case the doors malfunction or a spirit somehow forces its way through. The Voidling is the only way back from the Voidling’s Well after stepping through the door. Multiple spirits can be present at the Voidling’s Well at the same time, but they will never see each other. They won’t even see the Voidling, despite the Voidling seeing them. From a spirit’s point of view, they are completely and utterly alone.

The well connects directly to the void. There is no fabric to catch a spirit, although there is no need to. A spirit ready to move on will ascend the steps to the ledge of the well, sit down… reflect on their life and afterlife one last time. Then, they will let themself fall. As soon as their spiritual body leaves the realm of the Voidling’s Well and enters the void, it will disintegrate. The particles that make it up will return to the universe, and the spirit’s afterlife will officially end.
