A general term for all spiritual entities, except Egregores.
Our knowledge of the Spiritual Biosphere comes from research conducted by Research Temple Pytheas, as well as direct contact with Ihchghak-kee, and various spiritual entities. Progress is slow because communication in mokshaic logic is alien to material minds. Not to mention, the Ihchghak-kee were psionically mature far before humanity, and as a result manyof the patterns of the Mokshaic Membrane are adapted to their thoughtforms rather than ours.
