"Systemspace, in and of itself, is just a gigantic pool of Aurora. A System then shapes the Aurora however it wishes to create life, death, mountains, oceans, planets, space, its own perception of time and everything else.
Imagine a perfect empty System. It currently uses 0 hA (hA being a unit of measurement for Aurora). Now let's say we add a cube. A simple, plain white cube, that costs 100 hA. The System draws the necessary 100 hA from the pool (Systemspace), and uses it to create the cube. Destroy the cube, and the Aurora is freed back into the pool. In this example, Aurora is like RAM or disk space in a computer.
However, Aurora has a second function, and that is to spark activity. Aurora can think, to the point where its sentience is debatable. As such, Aurora is used for many things where "randomness" (or rather, a choice from outside) is needed, like creating universes or souls. Lastly, Aurora also governs the actions that are taken, by influencing the possible timelines and picking from them."
