@6slyboy6 Guess I'll get my concept pass you to see if it's okay. Disclaimer: I try to use a lot of "rule of cool".
So the general idea would be that my guys are really long living (and small, not Yoda small, think about 1.50m in general size). So most of them reach an age between 300 to 350. They live on a rather high-gravity planet with a VERY strong magnetic field that blocks some of the harmful cosmic rays and also holds the atmosphere in place. Which also keeps a lot of those cosmic rays out. Which is rather useful considering they fall outside the goldilocks zone (on the inside way, IE they're too close to the sun). So, despite the magnetosphere and atmosphere, the planet is still very hot but tropical. This, rather unique, situation causes a lot of metals and stuff on their home planet to be strongly magnetic (there are a few metals deep inside their ground that are superconductors at room temperature).
These aliens will be called Relicants (derived from the word Relic) by humans. Generally, because they have a very unique way of thinking. They are master artificers. In other words, whatever they make is of high quality and generally, lasts a lifetime (Relicant lifetime). Because they can grow to an age of 300, most aren't really in a rush so they perfect their skills. Engineers are as much practical inventors as they are artists. No human can really boast that their creations are as good as those of the Relicants. But obviously the production output of humans is near ten-fold versus that of Relicants.
Relicants, further, heavily encompass energy weaponry, magnetic fields, and railgun concepts. They have a low reproduction level so every Relicant is important (which means that there aren't many left, not near being extinct but their home planet will count 70% humans). In essence, Relicants use suits that can project energy fields or certain objects that can be supercharged before thrown (and then they explode in a very nice orb of energy). To give a general idea, I'm aiming to use science to replicate space-magics and I'll try to give a semi-scientific explanation for every tech used.
So what's their general deal? Well for starters, they are absolute zealots. Peaceful ones, luckily. But they believe that in a way they are either seeded on their planet or uplifted by their gods. Which live somewhere in the universe. Human propaganda obviously says they uplifted them. During the human invasion, the Relicants weren't really prepared for a war but still were rather compelled to do so. Which lead to a slaughter of their kind and the immediate pacification of their home world. Now humans mine their precious world for those superconductors. If you got more questions or anything, feel free to ask.
So what do you think?
