How the first flame appeared and the three lords as mortals

The appearance of the first flame was probably coincidental, we can just not know. But before it there were everlasting dragons, so perhaps something they did?

I think it was just a matter of when nature set things up. Nothing stays the same forever everything must end good or bad. So i think a few natural occurences happened and bam there was the flame. Now about the witch and Gwyn, i personally wouldn't be so sure. I really feel they were just hollows and they gained their souls when the flame appeared. Then that raises the idea of how humanity came into exisitence and that i feel is what had keep things going during the age before the fire. As another described it humanity is what allows people to be people and feel where as the soul brings realization and allows for conciousness so one know what they are doing. Now your idea on Nito i think is very pluasible since when you seem him he just comes up and out of the ground but i feel instead its their humanity that origanally brought them together to create him. The humanity idea is more my own idea so you can take or leave it. As for why i appeared to humans i can't say maybe it was another maybe it was nature giving humans a chance. Honestly i'm hoping it will be told in DkS 2.

I thought the witches created the demons because of them attempting to replicate the first flame

But your right i that this is fairly subjective on it's own, however i would like to quote something i think i heard that is very meaningful to the story

"The humanity is made within darkness, but are naturally drawn towards the light"

Weather the reason why the first flames occurred to us humans/undead is  mostly unknown, however what is known is that we as humans/undead are drawn towards flame naturally because of the lights it gives. And those who are the strongest will posses and the strongest of souls within the frist flame and become "god".

thus begins the age of fire, and we all know

"But soon, the flames will fade, and only Dark will remain"

All expect the pygmy, who disappeared without a trace. (some expect him to be manus, which could be a valid theory)

I'm sure most of you already know this, and probably these quotes are merely self explanatory, but i just like to repeat this part of the story for some strange reasons.

This was finished, in no need of a bump.
