Demons undergo a process akin to metamorphosis, transitioning through various stages, though not all may advance beyond the initial levels. Each stage represents a rung on a hierarchical ladder, with higher echelons possessing greater strength, altered appearances, and unique abilities. When a demon is slain outside the
Abyss, its
soul energy
returns to its point of origin. Conversely, those destroyed within the Abyss forfeit their
abyssal energy
to the world, their psyche fragmented into minuscule energy particles drawn back to the realm of
Chaos. Demon souls that return to the Abyss from another system must undergo a century-long waiting period before commencing anew. This extended reformation time is attributed to the sheer abundance of demons, a phenomenon uncommon in most other non-mortal realms. After the century-long penance, demons who were previously less than demon princes must restart at the lowest stage, becoming a lowly
Manes. Conversely, those who were once more powerful than a dretch often progress through the stages more swiftly, unless impeded by external forces, such as the
Buldumech. Entities that once attained the status of a marilith may only require a decade to reclaim their former stature.
There are numerous branches stemming from the most widespread Demon Stages catalogue below. These branches lead to additional branches comprising the myriad demon types dwelling within the Abyss. This list outlines the branches of the most renowned demon types.
