Alright I have a theory about their origins. So much of the Dresdenfiles is about the power of Belief, and it manifests into actual Beings. For example the belief in the season of Winter gives power to the Winter Sidhe. So just the belief in weather creates a source of power that can be controlled by a Being of some kind.
So here is where I think Outsiders come from. The fear of the unknown. I think that the fear of the unknown and everything associated with it is what powers them. It's why they are so completely alien, and terrifying. Because they are a pure unknown, malevolent force. They are all matter of mysterious terror. I think that just about any mortal Being (and probably many Immortal ones), have a fear of what they cannot know. TWG locked them out, and I'm thinking it's because TWG doesn't fear the unknown because all is known. Nobody else has that though. Everyone besides TWG has some insecurity towards the unknown, it's a primal fear for anything that thinks. That's a lot of power going somewhere...
Just an idea of mine. I also think that this unknown terrors could be a clue into Behind, Beside, and Before. What do you think?
It's not a bad theory. I would clarify though for it to work, it isn't the unknown that the Outsider would represent but the
unknowable. One is to pick a direction on a compass and head in that direction and explore, and the other is to say the compass cannot take me where I wish to go. The Unknown implies it can be discovered, the Unknowable can never be discovered. The latter fits the Outsiders better, at least to me.
It's fairly similar to the Warhammer/Warhammer 40k idea of the Chaos Gods - which were loosely based on Lovecraftian Entities. Jim himself was a big fan of Warhammer (and may still be) so it's possible he's lifted certain parts into his own works. In fact, I am fairly sure he has when it comes to his belief-magic mechanism. In Warhammer, the emotions and ideas of mortals take shape in the Immaterium/Warp/Realm of Chaos/Realm of Thought. These emotions and thoughts are what created the Daemons (old British spelling of Demons), Gods and other such beings.
While I think Jim has used some of that - it doesn't gel with his more recent statements about these beings like Angels and [some] Gods existing before time began and before the Creation Event. The Outsiders would naturally be a part of that - and Jim said the main reason they hate reality is that it's "too noisy" which suggests that they existed before the "noise" of reality/Creation.
My take would be that it isn't so much that mortals create these beings but that these beings already exist, and take the shapes of mortal concepts/ideas/beliefs within certain bounds. Sort of like filling a water balloon with different things to create different shapes. The balloon is the structure of the being which it can exist within, but it's mortal concepts that actually shape it. But the being itself is like the water or sand or whatever is being put in the balloon. Does that makes sense?
In the case of the Outsiders...because they don't seem to play by the rules as much as other beings my guess is that the battle they have is about will power - specifically free will. They are disordered beings forced to take shape because of Creation. Which they massively resent. Imagine if you were a multi-extradimensional being forced to be "real" and instead of being like a current in an ocean you became surrounded by land and cut off from the infinite ocean you once were a part of? Horrible. I think this is somewhat like what happens to Outsiders who come into reality. So they try and assert their will over local reality (wherever they happen to be) and try and change it into a more familiar state - chaos. Reality doesn't like too much chaos though and tries to order itself, hence mortals. Maybe that's the real value in mortals (in a sense). They always try and order the chaos. Even if they invite it in themselves. Almost like a perfect internal reality defence...
Anyway, I am getting ahead of myself. Back to my metaphor about balloons. If normal supernatural beings are like water in balloons being shaped, then Outsiders are more like the water trying to be it's own balloon and make it's own shape. Sometimes the mortals force it to be more balloon-like, sometimes the Outsider gets to be more water like.
I'm not really seeing it. I don't think there's been any mention of the Outsiders growing more powerful due to any human condition, has there? Beside talks about chaos being progress, but it's not like anything was said about them like it was said about the Eye of Balor. That fed off fear in general.
I still lean more towards fear being something Inside can use, but the Outside is beyond such things because they're just Chaos itself.
Like Serack's Theory, I think there was a balance of Order and Chaos in a space, and TWG separated the two, with Order staying inside and Chaos going out. And just like Avatars were made out of Order on the Inside, Avatars were made of out of Chaos on the Outside.
The only connection I see between Outsiders and fear in general is that fear can lead to desperation, which is close enough to chaos to help their agenda.
Do you have any examples of Outsiders and fear of the unknown, or any other fear? I know we're limited in what we've seen of them, but I can't recall much.
See, I'm not so sure there was Order and Chaos in the beginning any more. Jim has said it could be like that...but it isn't like he has said TWG is perfect order and Azahoth is perfect chaos for example. I am not sure he will ever explain it all that clearly. One thing he has said a few times is that Before (as in before Creation) was such a different mode of existence it would be hard for mortals to truly understand it, as we are beings of cause and effect (and before Creation cause and effect hadn't yet been invented). In a way, I don't know that it really matters whether Order and Chaos poles first existed or not, because "first" wasn't really a thing. The only "real" point of reference that is relevant is the moment of Creation, let their be light etc. Everything "before" then is beyond comprehension and all arguments are both true and false...which makes it semantics.
I do think perfect Order and Chaos exist
since Creation began though. I don't quite know what that looks like but I think that part of Serack's theory is essentially right.
Something along those lines, yeah. Primordial chaos.
But also, the Outsiders are the servants of the Old Ones ... who are still inside. The Walkers aren't the pinnacle of the lovecraftian pantheon, they're the knights of the even higher powers that were put to sleep in lieu of casting them outside.
Certainly some of the Old Ones. I am not so sure all of them are Inside. I am not certain that even all of them even ever got Inside the first time around. If Outside is essentially *infinite* then it could well stand to reason that there are infinite Old Ones and Outsiders, in the Outside potentially. A place of no limits doesn't have...limits. That being said I suspect (just like in the Chronicles of Amber, from which Jim has heavily borrowed) that the closer the Outsiders and the Outside are to Creation, the more "real" they are forced to become (like how close a Shadow is to Amber, the more ordered it is and vice-versa with Shadows near Chaos). Hence why Creation hasn't been overwhelmed by Outsiders yet. The Outsiders can't just break all the rules. Which I think is almost alien in concept to them as an existence of no rules or laws (in a physics sense) is to us. They are like the Machines outside the Matrix. They understand the Matrix to a degree yet they also can't quite grasp the nuances, the intangibles etc. They can no more enter the Matrix physically than anything else can. So they are limited.
I think it's the same for the Outsiders. They are forced to play by the rules when they get close, which already frustrates and confuses them in the first place, and then they are limited and can't quite understand the fundamentals of reality. So they are left to mimic and guess at it. Which means mortals end up confusing them - particularly like Harry.
