The plane that contains all the existing Eidos nodes and their energy. In the intersections with the Matera mostly can be found in Eidos interfaces. The plane itself was created by race of mysterious creatures presumably to collect data and knowledge and somehow share it.

Interaction with the plane can be performed through usage of Eidos interfacing.
