The Void

Overview
The Void is the intangible fabric of time and space that connects all things to the two Prime Forces. It is both a reservoir for all theoretical energy within the system, as well as the intangible force that gives energy a form. An extremely basic and simple explanation for it would be that it is the Universe as a whole, as well as all the matter and energy within the universe and can be accessed or manipulated in various ways by various objects and creatures. Inanimate objects interact with Void energy (qualified by its Alpha and Beta variants) but the extent to which is usually very narrow and specific to the type of matter or how the matter is arranged in spacetime. Charmcasting manipulates the connection certain types of matter have with the Void, using very specific kinds and exact amounts of matter to create Charm Cards, objects that essentially work as a programming language to direct the flow of alpha Void energy in a specific way to achieve a desired result.

Colloquially
The term "The Void" is often used in substitution for "the afterlife", as it is believed by most that ones life essence is returned to the Void upon bodily death.
