I believe that like most spellcasters, channelers are just youths who find that they have a very rare talent, the ability to shape the world around them with something called "magic", and then spend the rest of their lives practicing this new skill. Maybe in academies of magic or a personal trainer or master who teaches them "the ways of the Magic"

Personally I would say up until the cataclysm that the world was probably filled with channelers who made the world a better place, and there was a time of great learning and advancement under a so called Channeler Council. However, as the power of the channelers grew and the people became dependent on them to live, many of the channelers started to disagree with how the world should be shaped. A specific group of channelers believed that the world should be controlled, and the citizens minds enslaved by magic to keep corruption and crime down. They also believed in the study of necromancy and other forms of magic deemed "forbidden" by the Council of Channelers. In fact, this extraneous group proposed this to the council on several occasions, and each time their ideas of the world got darker. For fear that this group would cause too much dissention, The Elders of the Channeler Council decided to banish this faction from the Council telling the people that they had been "possesed by evil forces and demonic spirits" This group of channelers became known to the world as "The Fallen"

The Fallen were stripped of their magical essence and sent into the desert to reinvigorate their sense of the world, and to find "redemtion." However, the Fallen sought not redemption but revenge... They spent years in the desert, struggling to find the essence they had lost. They found that they could feed off the life essence from the creatures that lived in the desert. After many decades the Fallen found themselves back at their former glory, and with their essence they raised an army of sand elementals from the desert. At last the time for their revenge had come, and they waged war with their former people. 

Many innocents died in this so called "Elemental War", stripped of their life essence to feed the Fallen. Still other humans were subjugated and fed essence to make them stronger. They were stripped of their souls and and forced to fight as fodder in the Fallen's growing army. Soon, The Channeler Council became aware that their border cities were being attacked, and all of them rode out to fight what they thought to be an easy battle. However, what they found was that the Fallen's doctrines and beliefs had actually allowed them to become stronger than any channlers had ever been before... Fortunately, the Council still significantly outnumbered the Fallen channelers and while the war raged on for many many years, victory seemed just around the corner. The Fallen, sensing their defeated to be inevitable, sought to get the last laugh... They pooled all of their essence together and unleashed it upon the land. This act would one day, after many millenia, become known as "The Cataclysm."

Now, in present day, small pockets of humanity that somehow miraculously survived the Cataclysm find themselves still struggling to live off of a land that is utterly destroyed... All have forgotten the "Golden Age of the Channelers" and not one could recite to you how the world came to be as it is, other than to say that,"the gods have forsaken humanity." And while magic, for the time being, has all been forgotten, the time will come to pass when once again the world will see the channelers rise again. The philosophers all say you must learn from history, otherwise you are doomed to repeat it... But what happens if you dont know that history even existed?

 wow that was long but fun

So is there a small hope that at least one faction from the fallen won't totally obey to their creators?

@Vieuxchat: Well i think the creators are pretty dead or sleeping in some way.. Although they could make for fun expansion content, at most i think one faction of fallen would still try to follow their creator's last orders, but that is it.

@Lord Reliant: It's mentioned in the tiny lore section there is under the cataclysm and under the fallen.

And i do believe that would be the background story of the Silver cities it reminds you off, with the fallen taking the role of the necromancers to a certain part.

I understand this, but what is a "god" or a "titan", Imperial? Other than something or someone that seems indestructable compared to anything else in the known world? And the human fallen could just be followers (or more likely the offspring of those that were imbued by the ancient channelers to be stronger- this is my opinion of what i think would be cool) of the ancient channelers, just to say.

And if that much of humanity was destroyed, and nothing was left but a tale, the chance that these "powerful beings" would soon be translated as "gods" over time is not impossible to believe at all

Of course I have no clue what the truth is, I was merely trying to create a story based on what I currently knew, just trying to give what it could be, not what it is because unfortunately none of us know that yet! Except maybe for Frogboy    but im sure even he will change and add onto everything he has thought of by the end.

You're of course entirely right. I just never read it that way. I don't know how I read it. I can't explain it. I feel like a complete retard now, ignore my musings. I can't believe I somehow missed that, after reading it so many times.

I wouldn't be suprised in the least if they were humans themselves. Channelers, although in an era where magic flowed much more freely, and the war was, in the end, a war to control magic itself.

Perhaps titan could be used in some way, but it implies a largeness of some sort ! In power or otherwise. Also if you read the bit of about the fallen again, i rather get the impression that the "powers" are something quite different than humans.. Plus they would be more interesting than if they were powerful humans..

I think it would be cool to see a return of... well whatever these "powers" are, but yes I have to agree with Luckmann in saying that it sounds oddly similar to GalCiv 2 and while it was a great game, I think that so much more can be done than re-using old story elements

That's exactly what the DreadLords did lol they were just supreme beings that came back from a pocket universe that they had accidently trapped themselves in like thousands of years prior. And they came back and started kicking some major butt lol You should play GalCiv 2, I think you'd love it! If you are into space and TBS games of course. It really is possibly the greatest game i have ever played I mean with SD updates and everything is def the most well supported game!
