I'd like to make a new world of darkness, one that is centered on mage and changeling (which are the two lines most compatible in the old world of darkness), but which structures everything so that it's all nice a categorized:
Basically, the supernaturals are all split into four factions three that more or less correspond to one of the triat and serve antagonist roles.
Mages: The Marauders. Changelings: The Mad.
Mages: Technocracy. Changelings: Dauntain.
Mages: Nephandi. Changelings: The Thallain.
Wyld Factions seek a world were instead of one collectively agreed upon reality, everyone has a reality of their own, over which they have absolute power, everything goes as everyone lives mostly in their own world, even as they interact with one another. There is no separation between fantasy and reality, everything is supernatural as natural laws become a subjective matter, as such, the dreaming undergoes a similar fracturing, and each shard of it becomes much stronger, there's no distinction between imagination and reality, both become one and the same.
Weaver Factions Want the opposite, to tighten the consensus by removing all dissent, to purge the supernatural from the world and convert it all to the natural, a world such as this is one where free will is gone, and everyone acts purely out of logic and reason, and other species act purely on the evolutionary instincts to propagate their genes. Towards a world were human ability is maximized, the human race loses all individual distinctiveness, and people are basically turned into machines which act in a predictable manner, working towards the same personal goals by the most efficient route. Freedom, Individuality, and Magic are purged, to make way for safety, unity, and science, as for supernaturals, they are converted into "normal" humans, without any memory of their supernatural pasts.
The Wyrm Factions want to just hit the reset button, return everything back to the primordialism from which it came, and hope that the next time the world will be better, they long for the end of all things, so that a new beginning can occur, they look around at the world of darkness and see it as being irredeemable and beyond hope of salvaging, while they may be the stereotypical "evil" faction due to all the atrocities they commit, they do not see themselves with way, it doesn't matter what they do, as it's all just gonna be reset anyway, the end of restarting reality justify the means by which they achieve such a goal, they also point out that they are never senselessly evil, every wicked act they do is a step towards their ultimate goals, those who fall out of line and into pure hedonistic behavior are getting caught up in the world their factions seeks to destroy, thus sustaining it, so if they torture you, it shouldn't be out of deriving sadistic pleasure from the act. In practice though, they tend to draw in all manner of sickos just looking for an excuse to indulge in wickedness and gain infernal power as a reward for such deeds.
Note that all three antagonist factions have a goal that is terrifying to those who do not share their views, and all three of these goals require horrific acts of evil in their service.
The last faction is the player faction, who represents a balance between the forces.
For example, The mage traditions practice magic that imposes their will upon the world, but they also ground their magic in the beliefs people have about how magic is done in reality or fiction, and they hide their magic, living before human eyes as normals, lastly, they try to clean up the evil and corruption of the word as best they can, to make it a better place, without the need to completely give up on it.
