Axiom

Axiom is an aetheric substance, and is one of the components of aether. It's infamous in the Prime Chronoverse for being the power Devils draw on. Axiom is highly notable for its powerful reality warping capabilities.

Mechanics
Axiom is well known as a very effective source of reality warping - if utilized correctly.

There are two main modes of Axiom utilization: Generation and Simulation. Generation is the most famous of the two, as it is the method of using sheer belief in order to warp reality to one's whims. Generation can easily be done on the fly and without prior planning, not to mention by anyone so long they believe hard enough. Axiom engines, a tool used for axiomatic reality warping, are typically focused on efficient Generation powering. This is important, as it helps mitigate one of the major drawbacks of Generation: The fact it is highly inefficient and uses Axiom at a much faster rate. While technology can help with this and it's not as critical a drawback for Axiomatic entities, for people who aren't such entities it forces Axiom to have a heavy fuel cost. In addition, Generation tends to create less resistant creations, which can be easily overwhelmed by opposing reality warpers or things such as reality anchors.

Simulation, meanwhile, involves tons of work and study to perform, but it is overall agreed to be much more effective than Generation. Rather than believing reality and thus making it so, Simulation involves specifically rebuilding reality to be what the creator desires. In order to Simulate, an understanding of laws of physics and of how things function is vital. This is required in order to know how exactly to build something in such a state that it can exist. While precise exacts aren't always necessary as a rudimentary understanding often suffices, advanced Simulators will intensely study all possible aspects of reality in order to understand how to precisely create things.

The end result depends on the understanding of the Simulator. It can range from something that is resistant but not immune to other forces, to something that simply exists now due to being built in the precise exact way. Besides the knowledge curve, however, there is one massive downside: Simulation requires a ton of mental energy and brain power to work. As a result, Simulation can be slower than Generation and suck up attention from other things. Therefore, Simulation is seen as less effective in combat scenarios and more so for intense creative pursuits. However, some Simulators have managed to enhance their thinking to the point they can do their work as quick as any Generator.

Axiom Pools
The Axiom Pools are a series of separate subrealms that are nonetheless connected to the Aether Pool. Axiom pools form due to the fact Axiom drains away from other components in the pool, resulting in it collecting in those smaller realms.

Each spark in the multiverse is connected to a pool. Without a connection to an Axiom pool, sparks will starve and eventually disintegrate. In addition, each Axiom pool has an "allowance" for each spark based entity that is connected to it, which takes up a certain segment of the pool. Spark based entities draw Axiom for use from their dedicated allowance. Over time, Axiom from the Aether Pool drains in, regenerating its allowance.

The largest and most accessible Axiom Pool, also known as the Orgin Axiom Pool, is the pool that Devils are connected to. Due to the fact they all draw from the same pool, eliminating a Devil increases the allowance all other surviving Devils have.
