Reality Chart

The Dirkx Reality Chart is a method of mapping out various locations within the multiverse in terms of their relative permanence and entropic rating. It was devised by famous metaphysicist Dr. Allyn Dirkx as part of an effort to visualise and quantify the extent of the human race's consensus reality. While not entirely accurate, the Dirkx chart has been used as a rough estimate of the effect of anomalies on human consensus reality by Division Five, and as an educational tool in institutions teaching metaphysics.

Components
The Dirkx chart itself consists of two axes, most often with permanence as the y-axis and level of entropy as the x-axis. There are no absolute number legends, as the values of each location presented are relative values to that of Earth, A01, which rests at the origin. Worlds within the same magnitude as the baseline are considered A-class, those at the fringes of this area are B-class, and far-out realities with wildly different physical laws are considered C-class. Often an area is drawn around the A-class universes, constituting the human consensus reality, and the distance between each reality is the level of coherence between them. On Division Five versions of the chart, a large circle is also indicated, covering both the A- and B-class realities, referred to as the Central Unison.

The Central Unison
It was theorised by Director Gavaira Turval of Division Five that although they were integrating a significant number of anomalies into the human consensus reality and allow it to expand at an organic rate, there was a hard limit to the extent at which humanity could be aware of exophysical realities and concepts. Passing this limit would subject humanity to horrors truly beyond comprehension, regardless of any prior incremental incorporations of exophysics into human consensus reality. This is considered by some as an inevitability, including Turval herself.
