Forever war worldbuilding: enemy type
I've got a couple design panels planned out, but I draw slow and burn out fast, so here's the first of many.
The diagram is a presentation for one of the fundamentals of my Forever War setting. Humans have souls, and their mental resolve can influence how strong their souls are, similar to sanity.
Those who are weak of mind are more easily susceptible to the influence of void contamination, which takes the form of an intangible black mist. Prolonged exposure to the black mist will test and apply strain to the mind, like a cognito-hazard. Succumbing to it will cause the mind to break and the flesh to mutate, turning the victim into a rabid husk currently named 'Anomaly'.
Regardless of whether one was killed as a human or an Anomaly, their souls are materialised by unknown properties of the Abyss. This freshly 'resurrected' form will undergo an irreversible transformation. The cause is unknown, whether it be radiation or frequencies; the phenomenon is only known as the Song of the Void.
The end product of the transformation is known as Abyss-born, creatures with an insatiable hunger and orb-like eyes that can only see souls as a bright glow. A concept in development is that Abyss-borns grow through absorption of flesh.
Humans with strong resolves are more resilient to the cognito-hazard of void contamination. However, this plays in favor of the Abyss when they die. Their repressed traumas will be magnified by the Song of the Void, reflected in their grotesque transformation, resulting in a much stronger Abyssal-born.
