These principles are part of the Incarnaverse™ perspective. They are ours, and may not reflect your own or your group in all ways. They are intended to explain the design and development approach of the materials around the Infinite Incarnations™ (“Incarna”) game materials.
Do not let strict campaign or challenge level dictate your use of adventures. Both the story and play and PC capability should be able to be modified to support most measures of adventure requirements. A good Game Master can generally use the Incarna principles, system & tools to support them in telling their story with whatever characters and circumstances the Players have.
