Game world summary
Numenera takes place on Earth one billion years in the future. Earth is now known as the Ninth World by some because the civilizations of Earth have climbed to the heights of advanced society and technology 8 times before subsequently disappearing or meeting with cataclysmic disaster. The Ninth World is a young civilization built on the bones of those eight ancient civilizations.
At its core Ninth World society is only about as advanced as medieval Europe but they make use of the many technologies of the past ages left behind. Scavengers, scrappers, and adventures, explore ancient ruins and retrieve bits of ancient technology and material which are incorporated into the lives of the people of this era. The advanced technologies of past ages are collectively known as the numenera. The past civilizations mastered technology so advanced that they are indistinguishable from magic by many people. Most people barely understand the numenera and hold fearful or superstitious views, while others take more curious or scientific approaches to the numenera.
The setting for this campaign is the Steadfast. A relatively civilized area of the ninth world which is divided into 9 kingdoms. The kingdoms each have their own rulers, language, customs, & laws. There is sometimes strife between kingdoms but The Order of Truth manages to maintain relative order within the Steadfast.
