There are three afterlives That much is known. Those within an afterlife may reach out connect with those in another, or they may reach out and connect with the world of the living. These connections produce different kinds of magic.

The first of these is Rimevoid. Rimevoid -> Ashspark magic Rimevoid-giving magic chills, drains, and infects. It produces sickness, moisture, wetness, and takes away heat while also capturing it. It is hot and cold by turns. Life here is hostile, and drains life from other living things (xenomorphs/Venom parasites). It operates by principles of infection. It is the magic of Miasma. Rimevoid-> Ashspark magic is the magic of Storms. It enriches via deluge, fire, and lightning, which help replenish the fertile ground of Ashspark that the dead rise from.

The second of these worlds is Tinderbox/Ash-spark/Gravewood. This is a world of fire and ash, of light and smoke. Ashspark-> Mondas magic is the magic of Beauty. It freshens, clarifies, and streamlines, removing the complexities of a situation. Here, life is stifling and overwhelming. Here, there are ghouls, who eat flesh and form internal models of the people that they eat, holding onto their souls.

The third of these worlds is Firmament. The inhabitants fly through an endless, beautiful sky, and they seem as ephemeral as the visions that Gravewood can have of them themselves. All that is known is that Gravewood-receiving magic must be freeing. Here, there are poltergeists, who affect the world of the living by touching, moving, pushing, and pulling.
