1. Machina Mutatio: the literal mutation of machinery as a result of Netherforging.

Namesake: Latin - Machina(machine), Mutation(change/mutation). Simply, Machine Change/Machine Mutation. It causes the machine to fuse to the person, making i essentially a part of their body, akin to a cancerous growth. These mutations can go from the rather simple inability to disect the machine from the victim to the growth of functioning machineries onto the victim's body.

2. Netherforging: A form of Aetheric practise, in Netherforging a human or animal, the organism can be dead or alive, is heavily augmented with Dark Aetheric machineries. Netherforging causes Machina Mutatio/ Machine Change to take hold and causes the machine to fuse to the person.

3. Archon: A very powerful being, essentially a cyborg. An Archon is a godlike being which was made from Dark Aetheric practises, this practise is not Netherforging but, something even more complex that you'll learn later in the story.

3. Mendicor Units: Netherforged which were responsible for ensuring the functionality and performance of other Netherforged, repair machinery and to also work as mechanics. Mendicor Units are essentially medics and mechanics.

4 . Aetacinno: age locking, which was one of the only remnants of true Aether powered processes, nowadays in Neveros, this process was conducted onto sex slaves by their masters to maintain the slave's youth.

5. Era Styx: Namesake- Era of Styx(pitch black/darkness). The Era Styx was an era when the Archons turned on their creators (humans), this betrayal happened because the humans constantly fought each other and due to the constant exposure to violence, the Archons' true nature of darkness was reignited and they betrayed humanity.
