The Shape

The Shape is a trapezoidal symbol that has been widely researched and studied for centuries.

There is not much known about its purpose, apart from the fact that it seems to exist outside of the commonly accepted spacetime continuum and is consistently recognized by most people as something they've seen before, even if they can't remember where or why.

It also seems to be easily used as a "trigger symbol" to forcibly link together networks of thought and/or other energy in order to psychologically link people to those networks without their knowledge or consent. In this way it is somewhat similar to the DKMU's Linking Sigil.

The Shape was used to trigger Celia Cave's Enlightenment process in 2011 after her Treatment when she caught sight of it carved into her locker door. It was also displayed on the in-tank screen on treatment tanks.
