Rifts

Rifts are holes between the plane of existence and the void.

Overview
Rifts are largely temporary means of interacting with the void in a physical way. They act as a two-way stream of laws, allowing physical things to exist in the void and essential things to exist in the physical world. They can be created, through -Name Shifting, or they may occur naturally.

Natural rifts signal that the physical plane is breaking apart, and these rifts will continue to distort reality and exponentially grow unless the plane is stabilized. The longer that these rifts are open, the less that rules of reality, like gravity, form, and death, will apply to the world.

Mera
If Mera was to be compared to The Forces, then Rifts would be their element. They are the physical manifestation of essence in the only way that it can exist; by distorting the rules of reality. Rifts are fundamentally what allows Chiromata and Vile creatures to exist, as these forms themselves become rifts to the void, and thus embody its will and strength.
