Discovery is going to be a book that covers familiar territory for many of you. In fact, it can basically be considered a revision of the original Numenera corebook. Next summer, we will allow the original corebook to go out of print, and Numenera Discovery will take its place. In Numenera Discovery you’ll get some revisions to make things clearer and more fun, and to increase the options available to players. Nanos, Jacks, and Glaives will get an overhaul. Many foci and some of the descriptors might see some reworking. You’ll have more options, clearer rules, and perhaps a bit of expansion to the regions of the Steadfast and the Beyond that are covered in the existing corebook.
But this isn’t a new edition. We will make virtually no changes to the way the game plays mechanically—and none of those changes affect the way NPCs, creatures, or items like cyphers or artifacts work. We also won’t be making changes to the setting. This means your bestiaries, adventures, card decks, character portfolios, and books like Into the Night, Technology Compendium, and Jade Colossus will not be affected by these changes. We will not issue any “second editions” of the existing supporting titles—and if you choose not to get Numenera Discovery, future Numenera supplements will work fine with your existing Numeneracorebook. Your existing campaign will flow smoothly through the change in corebooks, with no need to plan changes or to in any way reset your campaign.
