From publisher blurb:
In the Ninth World, artifacts are items of ancient mystery and power. Compared to cyphers, they're relatively permanent and often have straightforward applications. But their workings are incomprehensible—a device powered by transdimensional siphons using nanotechnology to rewrite reality on the subatomic level often appears more magic than machine.
The Numenera Artifact Deck contains 100 new artifacts that haven't appeared in any previous publication. Whether you're looking for a little inspiration as you prep for your game, or need to come up with a artifact on the fly during play, simply draw a card. There's an image of the artifact on one side and complete description and game content on the reverse.
