I know that this question may look a little bit similar to this one: Realistic perspective on "shadow/void/darkness" powers? But I do believe this question is quite different
I'm currently developing the guidelines to explain the powers that some characters have on my story. Different "demigods" control one of the 6 basic elements: Fire, Water, Wind, Earth, Darkness and Light. They've come to a peaceful lifestyle by using their powers on a positive way, helping each other when needed and caring for the environment by maintaining an equilibrium.
Darkness powers, like fire and light, are of a destructive nature (this means that it has more agressive applications).
About positive applications: in the case of fire they can apply their powers to help some ecosystems that need fire to thrive (it's a real thing, there are a lot of research on this topic on the internet) and also control wildfires that get out-of-hand, etc..., light also provides benefits to the community by shielding their lands from the outside dangers, creating a magic alternative that mimics electricity on that world, etc....
My problem with darkness is that I'm short of ideas for giving them a positive use for their powers, wich are based in something similar to antimatter and some spare teleportation skills by traveling between dimensions, they excel in battle because they can create excesive amounts of energy (much more difficult to manage that the one light-powers provide) but apart from creating ideal environmental conditions to help some species that require darkness-ecosystems I don't find more applications for their powers.
A lot of the guidelines for the powers are based on chemistry and physics.
- Fire: They create spontaneus combustion in objects by weakening the bonds at molecular level, or creating friction between particles.
- Water: They don't "control water" they can manipulate the structure to freeze it inmediately or evaporate it.
- Wind: They have something similar to telekinesis and can also levitate by redirecting the wind around them using invisible molecule bridges.
- Earth: Controls and identifies vibrations on the structure of the planet.
- Light: Electromagnetism 101
And then there's darkness, the first thing I thought about was antimatter, somewhat allowing them to create an access to a mirrored dimension or create temporal-matter that has a highly volatile nature because according to a research:
"One thing for sure about antimatter is that it explodes when it meets matter. Harness that, and the possible uses are limitless."
Thing is, that the limitless possible uses I can imagine are pretty useless on the sense of helping a civilization persist or thrive on peaceful times.
¿Are there any possible positive uses for darkness powers? On the context of my story, apart from powerful weapons.
It would be nice to stay a little bit close to the "antimatter" concept, beacuse I belive it gives a little bit more of scientific-base to make it more realistic.
If you think I might need to re-structure my question to make it more suitable for this site feel free to mantion it on the comments, it's the first time I post a question.
