There are those among us that know how fragile our reality is.
They know that reality is but a thin membrane separating us from the Outer Black. They work to protect it from others that wish to manipulate it, shape it, and tear it for their own gain. They are the Esoterrorists.
The Esoterrorist’s tool is dissonance.
They plot and scheme to bring about creatures and events that warp the minds of the Sleepers. Each time they are successful the membrane that is reality weakens and thins.
It is now only a fine line that separates us from the chaos of the Outer Black.
