Polymemensional Runes, Sometimes called "The language of reality", are the written language of The Establishment and The Burning Sodality. The writing itself is interwoven with reality and shifts and warps even after having been fixed. The true meaning of each glyph is more or less psychically intuited rather than being "read" in the conventional sense.
those who have seen the writing (more properly an etching into reality) describe it as something akin to a "particle trail in a cloud chamber mixed with a circuit diagram. "
It is said the very act of inscribing the runes onto an object can change that object's properties, or even its destiny, which implies the runes have the capacity to alter the fabric of reality itself.
