AN: So, now that I'm done (finally) with my research, I've looked back over my original draft – and cringed. I mean, seriously, the guile hero is fine and all, but the other OCs detract from him a little. Not to mention what would happen if you deconstruct his circumstances.

Therefore, I will rewrite my story, while interspacing my personal take on the story of DxD's Demon King Satan Lucifer (No, you are reading that right) as a prologue and interludes between arcs, in less than a dozen parts. It will still be generally the same theme, just less...that.

I will also change my OC as follows: No memory loss, i.e. he mostly knows who & what he is, different 'human' form, and he's Issei's older foster brother.

And just to say right now: I will bluntly ignore reviews that count as flames to the source material. You call this madness?

THIS! IS! (FAN)FICTION! *dramatic kick*

If you want to learn everything about, say, Solomon and the Ars Goetia, you look it up online, as I did. If, however, you're here to read a possibly decent story filled with Fun Facts about religion etc, then you're in the right place.

Now, if the flames are directed specifically at my story, here, then fine. I'll take them into consideration, I promise.

Oh, and for those who want to know:

Nephilim: Angel-Human Hybrid(e.g. Akeno pre-demonification; Irina doesn't count[see below under Cambion])

Nephalem: Angel-Demon Hybrid(e.g. Akeno post-demonification, Issei's children w/ Irina&Akeno)

And JFF: Cambion(D&D: Tiefling): Demon-Human Hybrid(e.g. Vali; reincarnated demons don't count because their humanity was overwritten, same w/ reincarnated angels)

Prologue: Bringer of Light

Gathered brats, once upon a time –

Fuck this, I am not a damned fairy tale, you want my story?

Open wide and don't mind the texture:

I know not of the Beginning, whether of the world or of Him. I know only that He and several others, including two wyrms, one red and one black, were there when I was made.

I am the first of His children, made to be His voice, His hand, His ears. I was the Bringer of Light –

(Roll credits)

Silence!

– and thus was given two names, unlike my younger brothers and sisters.

In His part of the world, He made paradise for His new children, a man and a woman. The woman, however, was willful, and was thus cast out.

Looking back, that was the beginning of His, and my, fall.

It was not long after Lilith's exile when one of my brothers approached me. I had finished another sparing session with Michael and Azazel, both eager to learn all they can from me in person, an honor second only to receiving such from Our Father himself, which only I held, due to necessity.

I was venturing towards my dearest sister Gabriel when said brother came to me.

"Eldest Brother Sataniel, might I trouble you with my thoughts?"

He seemed nervous, and uncertain, both of which troubled me. I so hate seeing my family unwell, so I granted him a reassuring smile with my reply.

"Samael, you know rightly that my time may always be spared for any of you. Now speak, I beseech you: What troubles you so?"

"Tis the mortal, Lilith, and her predicament."

Ah. I was aware that some of our Choir were...discontent with the recent happening. That one of them bore access to the 6th Heaven was well within expectations.

"You wonder whether Our Father judged well?"

"Aye, you've surely noticed, but I speak not only for myself."

Laying a hand upon his shoulder, gently, but firmly, I answered: "Rest easy. For indeed did I notice, and thus thought to bring such grievances to Him at the first occasion possible."

"What is His word?"

"He spoke that certainly, Lilith was still his child, and as such, he dearly loved her. Her punishment, however, was for the betterment of the future."

"Stand He opposed to free will?"

I couldn't help but frown lightly at that, for such thoughts lead invariably down the Fallen Path.

"Where He so opposed, He would have ended her Himself. He is merely saddened that she turned from Him. Fear not Brother, for Our Father bears good intent for us all, now and forever."

I observed him heaving a breath, one that I took for him setting aside his mental burden.

"Verily, Brother, you speak truth. I shall act accordingly then."

I watched Samael depart with a light smile and conviction in his eyes, the former being mirrored on my face at another sibling whom I have helped.

I should have been more suspicious. I could have stopped him.

I could have saved Him.

Up in the 7th Heaven, I stood aghast at the sight before me. Our Father was there, his demeanor exuding something I've never before witnessed, nor thought Him capable of: purest Wrath.

Samael was there, bound to a cross, his face morose, but unrepentant. His ten wings were lessened to two, and black as the night sky.

"...Why, brother?"

His crime was the tempting of Eve, and through her Adam as well, to defy Him and eat of the forbidden Tree, all through the guise of a serpent.

"Your own words, eldest. Our Father doth not resent us for turning away. Even now, I feel that his Wrath is borne not unto me, but my guise."

The Lord's agreement rang through the space, followed by the verdict, which caused both of our faces to morph with horror.

For as the one to help birth this flaw in His being, Samael was to become the container of that flaw, which would become a curse against all serpents and wyrms.

Instead of begging for forgiveness own his own behalf, Samael simply hung his head, acknowledging his fate. In his place, I pleaded.

"Father, is this necessary? Surely, Falling him is punishment enough?"

My pleas were rebuked not by Him, but by my brother, for to me, he is still such.

"Silence Lucifer! I have made mine choice, and if you care for me even half as much as you say, then you will allow me to bear the consequences of my own actions with dignity!"

Our Father, however, denied the existence of dignity in his punishment, and assigned me to personally transfer His wrath into Samael's form. I offered no resistance, too stunned by my brother's accusation of any lack of love for my family.

As I held His wrath in my hands, I felt a deep, deep burn coursing through my arms into my center, before I tearfully lead it down my brother's throat, bearing his wordless howls of pain as well as possible, as his lower half was replaced by the tail of a serpent. Thereupon He laid various seals upon him, and I was instructed to take him down through the crevices of the Earth, to a place ruled by one of the 'gods' of a polytheistic pantheon, where Samael should have stayed shackled for all eternity, never to return.

As I returned to Heaven thereafter, I knew little of the seed that had been planted, nor the terrible, terrible fruit that I and my Lord would reap.

For those who want to know what Satan(iel) Lucifer looks like here, imagine an older Vali, around collage age, with a perfectly well-kept appearance.
