Technology

Technology in the world of Demonic Atomic is quite varying in nature. A few listed below are the common ones;

Steam
Steam powered technology is the most readily available since the planet healed since the bombs. Considering that most resources such as coal or pure nuclear material was lost to the nuclear holocaust, the regression to steam-based technology made the most sense as vegetation became a more viable resource. Tree growth is rather abundant in the wastes, and the generally denser woods make for excellent, slow burning.

Elemental Stones
Elemental stones are rechargeable energy sources created via vampiric alchemy. These stones are attuned to a specific force of nature upon their creation, and can be used to replicate the natural element they're aligned with. That said, activating them and keeping them from returning to dormancy requires radiation exposure. This effect is most commonly triggered by burning RadRock near the elemental stone, as the amount of radiation required is minimal.

RadRock
RadRock is commonly used as an activation catalyst for Elemental stones. Radrock is a quasicrystal that, opposed to being created due to impact at high heat, instead appears to be formed in the presence of demons as a byproduct of their radioactive auras interacting with the natural minerals in the ground around them. Aside from burning extremely hot for long periods of time, their use as a power source is also used in the operation of elemental stones. A small chunk of radrock (in an appropriate boiler) can power a very small village for about a week if used conservatively, so the resource is highly coveted for powering machinery. High efficiency steam engines often use radrock to help keep the main burning wood evenly lit in the boiler.

Geistfuel
Geistfuel is an extraordinarily rare source; energy extracted from souls. The process for creating geistfuel from sentient creatures is incredibly tricky, however is the safest and most effective energy source available. Being used similarly to gasoline, a geist engine is capable of being powered for extended periods of times on small amounts of fuel. While it's burning temperature isn't nearly as hot as Radrock, it burns even slower than the quasicrystal, making it particularly useful for powering smaller, more mobile machinery. That said, the creation of geistfuel does indeed require the ripping of someone's soul, and is often considered a fate worse than death. More often than not, Geistfuel is collected from materialized spirits who can be caught terrorizing the living denizens of the world.
