Type XXX

A Type XXX civilization exists beyond the highest planes outside reality and non-reality.

They are the Gatekeepers of the Beyond. They are the Beyonders.

Type XXX citizens live in the tenth level or tier of the Pyramid. The actuality of the Beyonders and their home is unknown and unknowable and is therefore a concept.

Concepts
The Pyramid is composed of multiple levels.

A Type XXX citizen is The Eye. The Eye sees the truth, but is invisible to all except as a concept.
