Author's Note: I would like to dedicate this multi-chaptered work to my friend who introduced me to Fanfictions and Good Omens in one go. I hope she reads this someday...
Disclaimer: Fanfictions are Works created by fans that are essential, different endings or background stories or different beginings to well loved books. They are a fan's take on how the story goes. This work, is exactly that, the author has made no money by creating this nor does she own the characters also associated with Good Omens.
Warning: Can you tell from the disclaimer this is my first fanfic? Crowley may be a bit OOC, Aziraphale may not be British enough (Curse my Americaness), Written by a Catholic/'why-trust-the-man-made-church?'/religion-of-all-kinds-lover and the Vatican-approved Bible at hand so be warned that I will be wrong at times and I do stray from approved bible. um, this chapter is K+ but later chapter's will change rating. Oh, hmmm, MalexMale kiss, which technically isn't since angels have no gender, but... Anyways, that seems like that's it for now... On with the story.

They had met once, before the day angels started falling. Gader'el was flying lazily amongst the clouds and not paying much attention to anything when suddenly he collided with something, or rather someone. They fell in a tangle of feathers and limbs to the soft solid ground below. Gader'el stood quickly to see what he had flown into, it proved to be another angel Aziraphale.

"My brother, I am so sorry." Gader'el said quickly, as he began to dust himself off. He spied a feather among his own deep blue ones that wasn't his own. This one was a soft white with its ends tinged in gold and with brown specks dotting it here and there. He took it out from his wings and inspected it closely.
"That's quite alright my dear, you're not the only one to blame, I should've been watching the skies." Aziraphale said as he too stood up.
"Well if you've accepted my apology may I ask you a favor?"
"Of course dear." Aziraphale said, wondering what favor he wanted.
"I wonder if I could keep this feather of yours." Gader'el said and held out the feather to Aziraphale shyly.
"Well of course, it is of no use to me now, can't really help me fly now can it?" Aziraphale said jokingly and Gader'el smiled.
"Thank you brother, it's a magnificent feather." He said as he held it up to the light. Then he remembered his manners, he had to give his brother a gift as well.
"Ah yes, well God be with you." Aziraphale said as he began to ascend, but was caught by the sleeve of his robe. A soft, shy, chaste, kiss was planted on his lips by Gader'el.
"Really, thank you brother." Gader'el said as he spread his wings.
Aziraphale touched his hand to his lips gently, wondering what had just occurred.
As they flew away back onto their respective paths, a thought occurred simultaneously to them both,
'I didn't even get his name.'

When the war broke out Gader'el found himself fighting his brothers, and he didn't even know which side he was on really. He respected God as any child would their father but it seemed to him that Lucifer did have some point as well. Besides this, there was no way to distinguish which angel was a friend and which was a foe, and that confusion could be felt all around. Some angels hesitated before striking, not willing to believe that this, this horrible bloodshed could be occurring on such a grand scale here, and against their own kind. Gader'el had gone to the secret meetings Lucifer had held, had listened to the knowledge the morning star was giving the rest of his followers. He was sure that Lucifer was right in what he was saying. But now, with feathers, sticky with blood, coating his sword, Gader'el didn't know who was right. Gader'el held tightly onto the feather his brother had given him. It was the only sure thing he had at the moment. Somewhere above him Michael and Lucifer fought, battling one another to the death. Gader'el looked up briefly and wondered 'why?' before he knelt at the floor and began to pray.
Somewhere across the field, Aziraphale thought the same thought. He had just fought someone of the opposing team with his fiery sword; he was knelt over praying for his fallen brother, his robe and armour were stained with blood. Blood that he had spilled. Blood that meant life was now all along the ground staining its pure white. He touched his hand to his lips and wondered how his brother was doing. In a panic he looked down at the face of the angel only to be relieved it wasn't his brother's. He looked down to the ground, closed his eyes and tried to ignore the chaos around him as he prayed.

Gader'el prayed that his brother was okay, he prayed that he would see the wings that he had loved so much when he'd first saw them. He prayed that his angel would never fall from the light of God, he prayed for his angel as the chaos continued to ensue.
Aziraphale prayed that his brother was alive, he prayed that he would feel those soft lips against his again. He promised himself that he would give the angel each and every one of his feathers just to see him alive. He prayed to God, to never let the angel out of His sight. He prayed as his world fell around him.
God was listening as always, and He found that these two angels were the only ones at the time who weren't praying for themselves. He found these angels were unknowingly praying for an angel on their opposing side. God smiled and thought, 'Let Their Prayers Be Answered.' And at that point, Michael won.
As soon as Lucifer was cast down, his most loyal followers fell. And after that every Angel that went against God. Gader'el looked everywhere for his brother, and Aziraphale did the same. For days after the war ended angels found themselves falling for thinking the wrong thought, for not having faith in the Lord. Every day, new lists of Fallen Angels were posted, and angels crowded around and wept for their brethren. These lists were no use to Aziraphale and Gader'el because they didn't know the others name.
Eventually, Gader'el began to believe that his angel had fallen.

'But I prayed to You Father, I asked You to never let him out of Your light. Did You forsake me out on that field? Was I battling on the right side, was going against you right Lord? It was so confusing, I don't remember who I fought or where I fought. I only remember praying to you. I fought against you my Lord. Should I even call you mine? Do I belong to Lucifer now? Is that why You forsook me? Is my angel amongst the Fallen?'
The ground opened besides Gader'el and a spiral stair case appeared leading down onto the molten dark world. He looked around. It was a way into Hell. He stood up and looked through the hole. Gader'el did not at first understand why the clouds had not opened beneath his feet but beside him. Then, he realized, this was a way to be forgiven, this was what he had to do to be embraced once again by his Father's everlasting love and Grace.
"Heavenly Father, I realize now that I've offended You. I've taken a step outside of Your pure loving light." Gader'el said with tears in his eyes. "I've never wanted this; it was never my intention to go against You Father. I am so sorry Father. My Lord, with Your help, I intend to do penance. ," he said gesturing to the staircase. "I will go where I belong, among the other fallen angels. Being apart from You and my Brothers who never offended you shall be my personal sacrifice." Hot tears fell from his eyes, leaving wet streaks upon his face. He could already fell the darkness tugging at his feet, the absence of His light was beginning to take hold of him. His Blue feathers began to tinge with black, his blue-black hair turned into a darker, pure black hue, while he could not see it, his eyes changed from the midnight blue into a golden honey color. "Today, I leave your grace, take care of my Angel. I'll keep this feather forever to remember the Grace I have lost today." He said as he took out the feather from his robes pocket.

And with that, Gader'el sauntered vaguely downwards.

Author's Note: Well, first of all, I named Crowley Gader'el because when I googled 'name of demon who tempted eve' the Wikipedia result said it was Samael. However, he is supposedly also the angel of death, which isn't Crowley. Then, it said that other sources said it was Gadriel. When looking him up on Wiki, I was redirected me to Azazel's page. Azazel and Aziraphale sound to much alike for my tastes.
Second of all, I used the American standard bible for references.
Last of all, i would love it if you reviewed because author's get some sort of high from it. I don't mind flames, I'll pull through. :)
