Before his mighty fall, Zachariel was a classically symbolical angel. He experienced little emotion-- just a solider of the lord, a pawn of a higher being. He followed every order to the T, leading him to the blessed position of being one of heavens favorite, despite being the youngest Archangel to that day. He was trusted with a very important job: safely leading souls to where they belong. Heaven, Hell --and in some extreme cases--Purgatory. He'd never had a say in where the souls were placed, but it cause him any aggravation. He trusted his father to know what was perfect for the person, as that was how he was taught. For the first time in his life he felt an irrefutable desire to go against his childhood teachings, all because a mare came waltzing into his life. Her name was Darcia. He had watched her in the mortal world she knew as her own since she was a year old. He had observed her maturity into a new version of herself when she was three years, and admired her strength in beauty despite the typically crippling changes. It was especially amusing to Zachariel that this mare danced with the Reaper, taunting him when she got to close. He was painfully aware that her time was nearly expired, but he lived in hope that she would live longer. When she finally fell, he led her to his father with a solemn expression. He expected her to go to Heaven, sure she had done bad things, but everyone had sinned at least once in their life. When judgement fell, he was dismayed. She was to be taken to Purgatory, to live a fate worse than hell and rot until she was hardly recognizable as the strong soul she was before.
That was the first time Zachariel had disobeyed his father--he spoke out of turn and was promptly punished for it. Without further disobedience, he led her to Perdition begrudgingly, despite her many questions and obvious fear—and left her without explanation. As time went on, and as deceased were lead to their Judgement day, a growing itch grew in the back of his mind. Even as he led souls to their new destination she was in his every thought and action--he knew down to his core her judgment was wrong, but he couldn't resist the Creator’s will. Disobedience to the creator would lead to a fate worse than Purgatory. He'd be going against everything he knew, everyone who cherished him and taught him his ways. However, his sense of justice was stronger than his obedience, and he left his position in front of Heaven's gates to search the depths of Purgatory. When he found Darcia—his Darcia-- she was half dead and torn apart, but still fighting for her life. He rescued her, taking her back to her mortal home on Earth, where he knew she could live safely. He took the liberation upon himself to heal her, but she attacked him with violence and vehemence, thinking he was there give her a worse punishment. After discreet some reassurance, she complied to his offer of generosity with eager aptness.
He protected the home which he placed her, taking his leave back to heaven. He returned to his post, acting as though nothing had changed. It seemed like his whole life had passed before he was called before The Creator himself. He was excommunicated, stripped of his grace, and cast down to Earth to live a mortal life. When he regained consciousness, his vision was gone. He could no longer see color, or the shapes he had familiarized himself with. When he looked at people he saw their aura –only as shadowed beasts, or celestial entities. Being a Fallen Angel, he was afraid and vulnerable. He ran blindly, and attacked anyone who came near him, good intentions or not.
He felt emotions for the first time, like adrenaline rushing through his veins. He felt heartache, grief, rage, envy, euphoria--all at once as one devastating emotion. Then she came, Darcia, with a gentle voice. She was different, older than when he had last saw her, and he realized that time in Heaven must be different than time her. It hit him instantly - he could see her, really see her. Not the aura of good or evil - but her. He saw her trusting eyes, and sloping neck; he saw her soft muzzle and dainty hooves; he saw her brindled coat—he saw the being she was, mortal, and beautifully exquisite in appearance and personality. Compassion practically radiated from her aura, soothing his senses and tuning down every immoral emotion he felt. She took care of him, nursed him to health and coaxed him into the real world as he had done for her. She taught him everything she could, of how life worked, how he would have to adapt. He wasn't the mare he banished to Purgatory, not anymore, and he wasn't the same Archangel she met on her Judgement Day.

note - Darcia and Zachariel's song is
Your hand in MindHe was a Fallen Angel, banished from everything he knew and loved. His vision gone, and cursed with the ability to see nothing of creatures and hounds. She was something unique, something he couldn't understand, something even The Creator couldn't understand. Now, they were stuck with one another, trying to ward off anything that comes their way. They have each other’s backs, fighting off Demons and Archangels, and even Hunters who come their way. After his fall, Zachariel changed as a stallion. He's softer, much more nurturing and compassionate, especially to his dear Darcia. He is the intelligence in the duo, always deliberately thinking things through while Darcia hastily rushes in, guns blazing and ready to fire. While Darcia is always tense, he has taken up a harmonious lifestyle. The only time he's in action is when he or Darcy are in danger—when they aren’t in danger, he tends to himself and others. Despite no longer having the graceof an angel, he still tries to help in anyway. He tends to the physical and spiritual wounds of others, even to those with demonic auras, as he knows what he sees is what The Creator's Judgement is. If he's learned anything, is that sometimes The Creator is wrong. Zachariel has taken it onto himself to overlook, even ignore, his sight, and often tells others that he is simply blind, rather than explain. He wouldn't want someone to be frightened, or hurt by what he says and who he really is.
He goes under the alias of 'Zach' and he often calls Darcia, 'Darcy'. However when they are alone, it isn’t common place to hear them use those names. Nothing is fake with them, nothing hidden or kept secret. Sometimes, late at night Darcia nuzzles herself into him because she's had another nightmare. He lays his neck across her, humming tunes his mother would sing to him as a foal to sooth him to sleep. Sometimes she would stay awake and cry and shake, choking out the dream between broken sobs. They always repeated themselves, always about losing him, or about her time in Perdition. He would murmur in her ear that he would always be there for her, and explain that even he has nightmares, but none of them are true, and will ever be true again. Times where he would dream he was still trapped in Heaven, in an endless loop of leading people to Judgement he would calm himself by listening to the rhythm of her breathing. He would thank her incessantly for breaking him from The Creator's rule, and she'd always assure him it was him who saved her. It was those nights that caused them to slowly fall deeply in love.

It wasn't until a year of them being together, hiding from danger and protecting themselves at all cost that Darcia confessed. Not a love confession, no that didn't need to be said. All this time and Zachariel never knew why she was sent to Purgatory, a place for monsters. His dear Darcia was in fact a very dangerous combination - a hybrid between an Angel and a Demon. Her body had a accelerated healing rate and she could teleport, all sense her birth. She told him all about her childhood, how the Angels rejected her but the Demons welcomed her with welcome arms. They taught her everything she could do, including teleportation and minor telekinetic powers. It all fell into place, explaining every little mystery that shrouded their relationship. That's why she could so easily avoid Death, why he was always drawn to her, why God wanted her to be gone. She was petrified, as every word left her mouth a weight was lifted off her shoulders that had been there sense the day she was brought into this world. He had never seen her look so defeated, so broken down she could drown in her own tears.
Darcia wasn't worried of about herself, she was scared of loosing the only person she had ever loved. The only person who stayed by her side, even when God himself was so against her. She had traveled through life being the out cast - not belonging with either side. Angels wanted her dead, Demons wanted her power, and the Humans didn't even understand what she was. The only light in her life was Zachariel - and she dragged him down with her.
It didn't matter to him, none of it did. Zachariel was banished from Heaven and stripped of his power, even rendered sightless but this wasn't because of her. He could have easily left her to rot in Perdition, but every ounce of his being screamed that she was to be saved. His purpose wasn't too lead souls to their judgement - it was to care for those abandoned by God. And that's what he did, alongside Darcia - the two traveling the world and helping those in need. People thrown into poverty, killed for their race or sexuality, those struggling to find themselves, these were the people that found themselves visited. They made a vow not to let God dictate how this world would end - who lived the high life while others died of easily treatable diseases. Stealing money, destroying harmful businesses, stopping wars, unsolved murders of people in high places, it was all thanks to them. They knew who were pawns, pieces in the game between God and the Devil. Existing only to reak havoc in a world they didn't belong in, thus they took them out. They were not Gods, not Angels nor Demons - they were simply two souls fighting for justice, even when every force of nature was against them.
