Classification 00-X is the first classification on the list of classifications, as these Divergances tend to be extremely rare.
The existance of a Divergance unable to fit in the other existing categories implies unique functionality that cannot be found anywhere else.
Divergances listed within this classification are tend to be kept secret from many of the employees, besides those in the upper ranks.
As many of these Divergances also have extreme drawbacks to knowing of their existances, and could potentially harm those who know about them.
An example of a Divergance being placed in the miscellaneous classification, would be a Divergance capable of ignoring the laws of space and time.
Even though it could be placed within the "object" or "being" classification, it would be much more accurate to place something of that nature
above such rudimentary and simple classifications.
