In the beginning, I was heading towards mechanical machines resembling our cliche' mechs as the main technology for Ancient Exiles. I then started to realize that it's been done before. It's nothing new. Mechs are really awesome, but I want my story, my world to be different; and for the main technology to be mechs... I didn't want to go in that route.
I then brainstorm for days and little by a little, I started to have an idea. The world of AE is not a fantasy world filled with magic and castles. It is a dark and violent scifi world that involves technology. So at the present time of the story, characters are known to use psionic abilities in a form of a mechanical glove. Attached to it (held in place when the glove is off) is a sentinel. An object or an orb that protects you when in danger and hovers around you when you have the glove on. Very powerful depending on the psi level of the character. It's full potential can only be used by few.
Psionics is the study of paranormal phenomena in relation to the application of electronics in case you guys didn't know. It amplifies the user’s psi abilities using Gaia’s energy output (which is sentient and everywhere). They are common in the military or any kind of government forces.
There are different types of psionic abilities in the form of electric, fire, force, and a few others. These mechanical gloves can also be modded which can amplify a certain characteristic of the user or other abilities to have an edge.
And a side note, as I was thinking about all of this, I developed a form of martial arts for the story. It's a sophisticated form of psionic-play called Psi Jutsu. Sort of like Gun kata to have an idea. It is mostly effective at close quarters combat and loses energy at long range which then dissipates.
I'll soon show some rough concepts of the idea. Thanks for reading.
