I've been toying with a rough cosmogony for
Ryngard (or any other setting, but it functions as a decent stand-in). I really like the idea of a setting with this as the underlying story; as it stands now, it leaves things extremely open, but also offers some nice options for the potential GM to play with. I'd appreciate any thoughts on this, especially the implications of the cosmological model. I've listed a few of my own ideas for it, but more are always welcome.
Concept:"Chaos, seething raw formlessness. A limitless expanse of unshaped potentiality, twisting and writhing within itself, comprising the entirety of Existence. A twist cascades into a series of turns, a bubble forms. The bubble expands, consuming unknowable quantities of Chaos probability mass in the swirling depths of infinity. The twists and turns of the bubble dictate the inherent laws of that which now resides within this small sanctuary of Sanity. Unlike the sea of instability raging outside the confines of what can be deemed Reality, there now exists a concept of Time, of the passing and changing of events with respect to a fixed reference frame."
Consequences/Extensions:~Chaos Beasts -- as with Reality, so with Chaos Beasts. Spontaneously generated, they're the result of raw chaos potential leaking into the bubble of Reality. Poof, instant monster to spice things up.
~No demiurge, no pantheon. Reality is the product of simple probability-munging and self-organizing patterns. Deity-level entities can certainly exist, but their origins are mundane; creatures and people that acquired phenomenal cosmic power.
~World-walking and Outsiders. Who knows what else lies within the vast tempest from which Reality was carved? Other realities might exist, were one able to find a way to bridge the gap across a sea of unfathomable madness.
~Chaos manipulation. Beyond normal magic, which operates under the strict rules of Reality. By manipulating the very stuff of creation, literally anything can be accomplished. Terrifyingly dangerous, however. Primarily cultists, Outsiders, and deities will use this. Expect horrific consequences, even if successful.
I don't expect this to be player knowledge, or even to really come up in casual play, but some of it would definitely color the setting in unique ways. The occasional Chaos Beast popping into existence would influence cultures, though how I haven't quite thought through (it depends on the rate of appearance). Chaos manipulation would provide cultists with an edge that the (mostly) rational PCs can't match blow for blow, as well as make for a nice segue into the occasional dark horror subplot.
