How he found himself, a fallen angel, being at the full command to a demon was just another long story Epsilon did not want to recall, but of course to start this whole account out he had to go back to the beginning, it was only logical.
The first thing that comes to mind when he thinks of how this started was the red string. How completely terrified he was to see the vibrant red loop tied around his wrist. He had fallen all the way from Heaven; it was weird to think that the thing that panicked him the most was that red string and not the pain of falling from such a high height or his broken wings which silvery blue feathers were soaked in wet blood, but the string. Angels all shared this genuine fear of the red string, as strange as it is, it has a significant amount of importance. The string, if tied on an angel's wrist, signifies the end of their time in paradise, whoever wears the string had sinned and as result got kicked out of Heaven, left to roam the mortal world.
Epsilon knew this which is why despite all his injuries from falling, he just couldn't move and was frozen in place staring at the string. His first reaction after the initial shock wore off was to try to tear the string off, hoping he could remove it, hoping he would be different from the other fallen angels who failed to get the string off, but it was impossible. The string was permanent to rest on his wrist. The realization of this brought Epsilon to reality and he finally started to feel all the pain he was in and his own quick panicky breathing he had as he shook like a leaf. His next reaction to all of this was more desperate as he just looked up to the gray sky and screamed, screamed and sobbed for forgiveness, promising he would change if they brought him back, saying he was sorry… But it was no use. Nothing happened, no angels came to save him or bring him back, and he was stuck here, alone.
The only thing that got him up off the muddy ground was when a newly made angel came, her name was Maria. She cleaned up his wounds and calmed him down. Epsilon ended up helping her in return by telling her husband that she had passed. Mari and Epsilon both seemed to make up for something the other was missing. For Epsilon she was like his new mother figure, one who didn't care he was fallen or for why he fell. For Maria, Epsilon was like her child, making up for the two she left behind when she died. Sadly, all good things have to come to an end, and she had to return back to Heaven. The last thing she said to Epsilon was that the next time he saw her she'd be fallen too. He didn't know what it meant, but had a bad feeling about the fact she made it sound like her falling was a definite thing.
The weeks after that went by slow. Epsilon didn't eat or drink, rarely even slept. He spent most of his time walking down the streets like a zombie among the mortals, using the last of his power to just stay hidden from them. Epsilon didn't bother trying to remove the red string anymore, he knew it was impossible and just kept it as a reminder now that the world is unfair, how something so innocent got him kicked out of paradise and took almost everything he had away from him. He felt numb. If he died here no one would even care. Everyone who used to care about him didn't fight to keep him in Heaven; they all turned their backs on him once he was named a sinner. Somehow, though inside he felt like death, his appearance still stayed normal. His medium length black hair kept well, his skin its normal pale color, his wings had been cleaned up by Maria so now they were back to their silvery light blue color, they were still broken though, the only thing that showed any difference was the absence of a halo and his eyes. Instead of showing his old optimism and happiness, the blue orbs only showed pain. Yet throughout it all he was still holding onto the small hope that maybe, just maybe, they'd take him back. He didn't exactly sin, just barely, so… Maybe there was hope.
Epsilon was snapped out of his self-pity when he heard a screech. He looked up to find no one else was walking around the wet, puddle infested side-walks anymore. At first the area looked void of anyone but then he saw the lifeless form of a body lying down on the ground covered in scratches and burn marks. Epsilon, despite his initial anxiety, slowly walked up to the man and looked down at him. The wounds didn't look like they had killed him, and Epsilon could just see the life draining away from him as his skin paled. Epsilon made note that the man's face was twisted in terror, like he had seen something he shouldn't have. Epsilon looked at the burn marks curiously, wondering how he got them in the first place. They looked new but there was nothing around here that could've burned him. Epsilon debated what to do, whether or not he should bring this guy somewhere or leave him here, he didn't want to be blamed for this and get in trouble though. Epsilon sighed and stood up, just as he did though he heard a hiss and the collar of his white button up shirt was grabbed.
"What are you doing here angel?!" A voice asked. Epsilon quickly looked to see who could've possibly grabbed him. He blinks when he found it was the shadow of the man, though it had horns, wings, and a tail. The shadow started to form into a physical state and what Epsilon easily recognized as a demon. He had dark brown hair, green eyes, and a grayish skin tone. Two horns poked out of his curly dark brown hair, he had black bat like wings and a red tail like all demons do. He was taller than Epsilon and something about him made Epsilon a bit more self-conscious about himself. This demon looked like he had been an adult when he died, fit and in his twenties at least, meanwhile Epsilon looked like a child. He had died when he was seventeen and was now stuck being a skinny, short teenager for his eternal life.
"I asked you a question." The demon growls, crossing his arms and getting Epsilon's attention back. Epsilon blinks and rubs the back of his neck, a bit nervous since the last thing he needed was to piss of a demon.
"I um… heard a scream and came to see what happened….. Did you do this?" He asks causing the demon to smirk.
"Maybe, maybe not." He replies with a teasing grin that obviously said he did.
"How could you? That's cruel!" Epsilon exclaims, thinking everyone would have the common decency to know that killing random mortals was immoral.
"Did you forget I was a demon? How could I resist?" The demon replies with the same teasing smile, trying to get a rise out of Epsilon, who just scoffed in return.
"Wow, you have no self-control." Epsilon states flatly, gaining a chuckle from the demon.
"Well thanks. Now what's one of you pathetic, goody two shoes angel doing down here? You guys are usually too prudent to actually come down here and interfere with mortal affairs." The demon says. Epsilon could feel the demon's eyes trail down him like he was a piece of prey; he noticed they stopped looking at where the red string was. Epsilon quickly hid it but the demon had saw, for his grin grew wider making Epsilon more nervous. He went to tear his other arm away from the demon but he tightened his grip.
"So fallen angel huh? You were such a freak that they didn't even want you up there?" The demon chuckles towering over him, knowing he was touching a sore subject.
"They kicked me out because I sinned. Not because they think I'm a freak." Epsilon replies though it was obvious in his voice that the demon's words struck him.
"Whatever you say~" The demon says in a singsong voice, really trying hard to get the angel upset. Epsilon glared at him, hoping that he really could kill the demon then and there, but there would be two problems with that. If he killed the demon his chances of getting back into heaven would be forever shattered, for that was one of the more serious sins, and also Epsilon wouldn't be able to face the demon with the little power he had right now, the demon would easily kill him.
"So, what's your name?" The demon asks after a moment of silence.
"…Epsilon…" The angel replies after a hesitant moment, not really sure why the demon wanted to know.
"What a beautiful name~" The demon hums, grinning. Epsilon chewed his lip, forcing away the hint of blush that formed on his cheeks, he didn't know what the demon was doing, only knowing this was dangerous territory.
"What do you want..?" Epsilon asks, not meaning for his voice to be so shaky when he asked but he was nervous. He kept trying to get his arm away but the demon wouldn't let him.
"It's not what I want… It's what you're going to be doing for me… You're going to be my new slave, little angel." The demon says giving a toothy grin. If it wasn't for the initial shock of getting told he was going to be a demon's slave, Epsilon would've been pissed at the nickname.
"What?! No!" He yells in response.
"Why not?" The demon replies gaining a glare from Epsilon.
"Because I have dignity!" Epsilon replies. The demon scoffs.
"Well too bad. I never had an angel as a slave before…" He says, a grin forming again as he puts a chain around Epsilon's wrist that didn't have the red string. Epsilon tried to get it off but the chain tightened.
"I wouldn't do that if I were you, fallen angel. You're mine now." The demon said, making a small chuckle at the angel's efforts to remove the chain. Epsilon couldn't do anything more, he knew if he tried to fight he'd be killed and he couldn't talk his way out of this, so now he was just shaking, realizing how things had gotten from bad to a nightmare. He was in a lot of trouble now.
This is where the story began, and then he was being dragged by his hair into a portal that lead to the scorching hot land of the banished dead. He didn't understand, he couldn't understand, why such an innocent sin had led him to this. He didn't know if this was really his punishment or if this was just a series of unfortunate events. Either way, he knew this wasn't going to get better. No, it was never going to get better. He had both the red string and the chain to remember that.
