A Campaign's main responsibility is to communicate clearly, both with its players and with its Games. This means creating a cohesive cosmology, monster manuals, rule set, a game world, and making certain that the people who run and play the Games within the Campaign have the parts of this body of knowledge that they need.

Since Campaigns can vary greatly in their cohesiveness according to the needs of the Games, this level of connected information can vary as well. Each Campaign Committee must strike its own balance of freedom for the individual Games and the cohesion of the Campaign as a whole.
