Artifacts are the tech devices that you probably expect in the game. These are devices of a more permanent nature (unless they run out of power) with more straightforward applications. Weapons, armor, utility items, and so on. Still, rarely are they straightforward. It’s far less likely to find a "gun" than it might be to find some item that can be used effectively as a ranged weapon, but might have originally been some kind of power conduit that has been modified and adapted as best as Ninth World understanding could manage. Some characters, given the right tools and parts, will be able to construct these on their own.
