You can also detach technology from factions. Ceruleum is more interesting if it is merely a basis for technological progress rather than "the thing that makes the evil faction tick". And this feels like an apparent plot point that is going to happen in Dawntrail, there are people who are not the old evil empire faction trying to do stuff with that.
Same applies to all the other form of technology seen here and there in the game's setting. If you wanna get really abstract and reductionist, everything just boils down to aether anyway. Everything ends up being just "a way to burn aether to boil water."
