The Void

The Void is the absence between universes/multiverses within the Outsider Multiverse. The location itself is described by many as an eldritch hellscape and primordial soup, being both formless absence and the well of infinite potential from which universes arise. The location is filled with eldritch substances/energies, and is completely devoid of any laws of physics or time and space. It is also a strange source of power, and the key to the process of Transcendence. Raw Void is often referred to as protoplasm.
== Location ==
The aptly named Void is located outside of any given cosmology, and exists in regions without physical space to occupy it. There are different regions within the Void, but it is extremely difficult to quantify a universe/multiverse's given location within the hellscape due to the lack of any space or time to act as a reference point, except in relation to other cosmologies. It is thus up to a traveler to force some semblance of order on the Void surrounding them to navigate their way through it; for beings like the Transcends, this is through manipulating the Void, and Old Brethren, by forcing their own laws of existence on their surroundings. Universes and remnants of them can exert a certain amount of influence on the Void immediately around them, making it possible for those without similar abilities to navigate their way through this absence. When an un-region of the Void spontaneously forms some semblance of order and existence and thus a coherent set of physical laws, a universe/multiverse is born. By the same token, when a universe dies, the space it once occupied is filled once more with absence, though traces can remain in the form of Protean Traces or other forms of decaying universal debris. Universes/multiverses within the Void can drift and cluster into reefs and groups, and in turn these universal groups can form superclusters. Conversely, groups of universes and multiverses can also be born within individual regions of the Void, often through the Pools of Possibility; regions that have spontaneously become ordered enough to give rise to (often multiple) realities. Travel between different universes is possible without transport through the Void (such as with wormholes), but the universes must in some way be connected or cosmologically touching/extremely close within the Void itself. 
== Applications ==
The Void and the energies and substances contained within are extremely highly valued for their abilities to warp reality. Many forms of godtech utilise the Void, as do the Transcended and the Outer Gods. Raw Void protoplasm, when used without any filters or focuses is highly hostile to reality, warping and destroying space and time while replacing them with nothing. Put through a focus, such as the will of a Transcended or Outer God, and Void protoplasm can be used to override and warp reality. Raw Void by itself is completely indestructible, being undamaged by physical, metaphysical or conceptual effects. 
Technologies utilising the Void are known as Voidtech. The production of this type of technology is heavily monopolised by the Transcended, Godminds and Outer Gods, due to the fact they are often the only parties able to mass produce them reliably. Without any of the three types of beings above, creating new Voidtech is a tedious and expensive prospect, requiring objects to be exposed to minute concentrations of Void protoplasm over a prolonged period of time, allowing the object to be changed by its presence without destroying it. Exposure is difficult to control for entities that cannot control directly control raw Void, like the aforementioned beings. After an object has reached saturation and has been successfully changed, the parameters for this successful attempt then be duplicated to mass produce it. This process is often one that falls to chance, and attempts can vary from as a low as a single one to truly astronomical numbers of tries before successful parameters are found..
== Patterning ==
When Void protoplasm has entered a universe, it intersects with reality and its laws. Due to the nature of this intersection, there are some semi-consistent ways in which the Void protoplasm interacts with most realities. In minute enough concentrations, Void protoplasm will gradually change matter and energy, converting them to Void protoplasm. While in larger concentrations, raw Void will completely destroy matter/energy, time, space and the fabric of reality it makes contact with, leaving nothing behind. It is in these small concentrations that the process of patterning can occur, where the original entity can be preserved from the beginning to the end of the conversion. Patterning allows an object or process to be changed by the Void through gradual and prolonged exposure, and once something has reached its limit of saturation, it becomes a 'pattern' in the Void. The pattern is indestructible (inheriting this property from raw Void), even from effects as destructive and absolute as those employed by The Silence. These patterns cannot be destroyed nor be made inactive, but can be changed in some ways, as long as the changes do not result in either destruction or inactivity. An object's or process's physical form can be destroyed, though it's pattern will remain intact. This process, when used with a mind and/or soul is the first step in Transcension.
