I might have already talked about this in the comments under a different post, but wanted to make it its own topic of conversation, so take this idea as a prompt as well, and feel free to add your own takes on the idea.
Chaos and Order are the two fundamental forces inherent to all existence:
- Chaos is the force of creation, change, and motion.
- Order is the force of stagnation, logic, and stability.
Either force alone is incapable of creating something interesting and lasting:
- Chaos would end up destroying whatever it created by creating something on top of it immediately as it lacks patience.
- Order would choke a world to a cold, stationary death because it lacks creativity.
When the two exist alongside one-another, or even mix together in any ratio, they end up creating living, changing, interesting things.
The creation of the universe Eldara resides in happened at random in the eternal sea of Chaos. It popped into existence by sheer chance, and Order immediately took hold of it, creating a sort of stable bubble in the Chaos-ocean.
Another thing I like to believe is that any sufficiently large amount of energy or complex-enough system will develop a kind of consciousness of its own, and so, the "bubble" itself - the barrier between Chaos and Order - is a kind of god, called Eldritch. It acts partially as if it was alive, with a kind of metaphysical metabolism, and healing from injuries sustained from both without and within. This is relevant because the timeline of the Mortal Realm, which hosts Eldara and its star system, is made of the combined/woven-together individual timelines of a new set of gods called the Nex, which, in turn, all sprout inwards from what is the equivalent of scar tissue on the side of Eldritch, following a rupture event caused by a particularly strong wave of creation within the Chaos-Ocean.
