A noosphere is the emergent psionic potential of a large population of sapient people. Normally, non-psionic individuals have a negligble influence on reality- they cannot manipulate substantial amounts of anomalous flow and only produce very small amounts of cuil flux. As a collective however, the interactions of a large number of conscious minds allow for psionic effects to take place- very rarely. These collective consciousnesses are called noospheres, and typically make up individual colonies or planets.
The psionic effects of a noosphere can vary, but are typically incredibly rare as they require synchronicities across the entire noosphere that create the will required to enact psionic power; common patterns in thought across the collective, or focused attention on a certain concept or event may rarely lead to a noospheric effect. Such "noospheric events" occur only a certain number of times in a specie's entire history. Some noospheric effects include the creation of egregores or localized anomalies, but the sky is the limit; a noosphere could cause certain supernatural phenomena to transpire, lead to the creation of anomalies such as manifests, or even cause a specific individual in the noosphere to awaken.
