ACOTAR MASTERLIST
🖤🖤🖤
You looked at your reflection for the first time in months. You barely recognized yourself anymore. Your cheeks and eyes were sunken, your ribs were protruding, and your skin held an ashy undertone that wasn't there before.
This is what abandonment looked like.
Longing stares never returned, his hand adjusting to evade your touch. A bed is left cold on one side. Friends who once joined you in joyous laughter barely acknowledge you at dinner. You had become a disease that no one knew how to handle but would be relieved if you disappeared.
It hadn't always been this way.
Warm calloused hands holding you close the scent of leather and sandalwood surrounding you. Cassian nibbling your ear, or stealing you away during meetings to steal a kiss, maybe two. Dinners at the rainbow, watching a storm roll through Velaris in the comfort of your balcony and his arms.
The early days of your relationship consisted of stolen kisses, discussions of hopes and dreams, that as centuries went by, morphed into talks of building a future a family. He was your person, and you were his, and life seemed bright.
Until you weren't.
Nesta Archeron was not a female to compete with. And how could you? She was elegant and sharp, and she was beautiful. She also challenged Cassian, fighting back with that quick, sharp tongue of hers, ways you never did. Then you felt it before he did, the shift, the snap. He had found his mate.
It wasn't you.
And the heartbreak of that fact would have been fine had Cassian consoled you in any way. When you needed his comfort and touch most. He was gone. He first stopped coming to bed, and when he did, he turned and faced away from you. The action alone made you feel like he was doing it as a chore, not because he found comfort in your warmth. Maybe he even thought he was being kind. It just deepened the wound festering in your soul.
Next was his things, books went missing, then his weapons. It was when you walked in on the Illyrian packing his things that he confronted you. "She needs me, sweetheart. I can not abandon my mate."
But I can abandon you.
A hand on your shoulder was the only comfort you received. His face held no remorse for the pain he was putting you through. You cried in your bathroom it wasn't until the next morning when you were in the same position the cool tile kissing your skin that you realized you had fallen asleep. You didn't leave your room for days, and no one came in to check on you. Not a single knock. Turns out you were only worth loving so long as Cassian did.
And he didn't. He had Nesta.
You had no one.
You were beginning to sink to a dark, inky place, the wound in your heart growing with infection, and your heartbreak was turning into rage. The feeling scared you. You ran to the one person you thought would be able to help you.
The High Lord of the Night Court.
You knocked lightly on his door. "Come in." His tone short. You walked in, not letting yourself think too hard about how busy he must be. He didn't even raise his head when he said, "I've been wondering when you would come visit." He leaned back in his chair, violet eyes, meeting yours. "Please sit."
You sat at the seat in front of him and took a deep breath. "So you know why I'm here?"
"Cassian and Nesta?" He quirked a brow, and you nodded he sighed and pinched the bridge of his nose. As if you were a hindrance in his life. Kind, loving, Rhysand, even found your presence as an inconvenience. "What would you like me to say, Darling? They are mates they are allowed to be together."
You dug your nails into your palms, trying to reign in the rage. "So you're okay with him not even saying two words to me since they met?" Your voice began to rise in volume, "He tried packing his things in times I wouldn't be home so he could avoid talking to me." Your rose from your seat and Rhysand stilled as lights flickered around you that you failed to notice. "You all act like I'm not apart of this family anymore. I could dissappear tomorrow and no one would care if you even noticed at all."
"So leave." The lights snuffed out completely. You thought it was Rhysand's power never once, considering it might be your own that had laid dormant for centuries. Or that said power stirred something deep in the realm where a manor resides on a lake. You could only focus on Rhysand's words and the cold tone he said them.
He was no longer your friend. He was your High Lord. Nothing more.
"Well. I won't stay where I'm not wanted. I would have thought a relationship that had lasted centuries deserved him, at least telling me he wanted to try with Nesta." Tears were falling and you didn't stop them, "I wouldn't have fucking stopped him. I would have been happy for him. He didn't say a word. He took the cowards way out. You all did."
"I'm sorry, Darling." Rhysand didn't mean it. The smirk on his face said it all.
You turned and walked away, pausing at the door. "No. You're not. But one day you will be." And you stormed out. Not bothering to grab your belongings, you didn't need the reminder of the court of dreamers casting you aside as if you were their personal nightmare. Not interested in speaking with anyone. They weren't interested in stopping you from leaving.
You. Were. Done.
🖤🖤🖤
You walked for hours, your feet were sore, back drenched in sweat the most you had done in months, since Cassian didn't care if you had shown up for training or not. Needing rest, you found a tree to lean against. The sun began to set, and you were ready to give up. Let the beast of the forest consume you whole. If you died, then maybe the ache in your chest would cease and you could be free again. Whole again.
You again.
You sipped from your canteen when you heard humming. Your pointed ears perked as a hunched over woman approached you. You recognized her from Rhysand, projecting Nesta's memories into your head. For extra torture, he had "accidentally sent a memory of Cassian pleasuring Nesta," You had sobbed profusely that night. "Briallyn." You whispered.
The crone stopped in her tracks. She turned to you, your eyes locked on one another, and you couldn't help but relate to her. She wanted a better life for herself, only to be thrown in the cauldron and spat back out. Both of you former shells of what you used to be. "My my, you look positively dreadful."
You snorted, "So do you."
She laughed, "What brings you out here alone? That brute finally get sick of you?"
You sharply inhaled a breath at the question. "He did, actually. I am doomed to wander these lands courtless," If you even lasted the night.
Briallyn waved her hand in dismissal, her now aged hand grabbing your too frail hand. "Not all who wander are lost, dear. I was asked by a friend to retrieve you."
"Who is your friend?"
"Someone who has a special interest in you my dear." And the Human Queen turned Crone led you from the forest further from the town you once called home and the only thing on your mind?
It was nice to be holding someone's hand.
🖤🖤🖤
The throne room was dark and cold, as if death itself resided here. The only vibrant color here was the Phoenix that was in her cage, pulling to break free.
Vassa was here.
Briallyn squeezed your hand, and you felt comfort by the warmth of her touch. As you approached the male on the dais. He looked young, and you gasped as his beauty was beyond compare. The most beautiful male you have ever seen. And then he grinned, and your heart fluttered. The General of the Night Court long forgotten as you stared in the males cold eyes. Briallyn bowed, tugging your hand as you made to do so too.
"No, need to bow, Pet." You paused, straightening your posture once more. "Do you know who I am?"
You swallowed the sudden lump in your throat. "You go by many names. Old god, death lord, most call you Koschei." Your voice held a tremor as you were in the presence of a powerful being. A being whose brother once went toe to toe with the Lord of Bloodshed and almost killed him.
Koschei nodded, "Come closer, let me take a look at you." You looked to the former Human Queen in panic, afraid to lose her touch. "I promise I don't bite." You approached the dais and couldn't help the trembling convulsing through your body. The death of the Lord's dark eyes roamed your body. He rubbed his angular jaw, and your eyes met his lips as he tucked the lower one behind his teeth.
Beautiful, he was absolutely breathtaking.
His voice broke you from the trance like state. "My dear, someone has hurt you? What did they do to you?" He leaned forward, grabbing your hand and placing a light kiss on your knuckles. Tears brimmed your eyes. When was the last time someone harbored any affection toward you. "Tell me, sweet girl." Another kiss and your composure broke. You fell to your knees, and a matter of hours went into painstaking detail of how the Night Court had abandoned you. When you finished, there was a lightness in your chest.
Maybe there was hope.
"Oh, you poor thing." Koschei cooed, tilting your chin to meet his cold eyes, "If I had you, I wouldn't let you go so easily." He wiped the stray tears from your face. "Be mine, and never feel that pain again."
You lip wobbled as the cries of the Phoenix caged beside the old god broke your attention, the shrieks louder than before. Koschei gripped your chin and had you facing him once more, his face inching forward. His lips pressed yours, gentle and promised warmth, love, power. You felt as though he was breathing life back into you, and you relished in his lips touching yours. He pulled away, "What do you say, Little One?" A voice in the back of your mind screamed:
Right
Right
Right
You smiled for the first time in well over a year,"I want to be yours, Koschei." Magic thrummed around you as his smile turned sinister, gold chains clamping to your wrist, a collar latched around your neck. Scantily clad in a black sheer tip, only covering your breast and a skirt that barely covered your ass.
Koschei smirked as he gripped your waist and placed you on his lap. "What a formidable pair we shall be, my pet." Making a onyx crown and a matching ring appear, he gently placed the crown atop of your head, sliding the ring on your finger. You admired the ring, a small smile on your face, and something pulled at your chest at the thought:
He was claiming you. And you loved it.
Looking at the beautiful face of death and pressing your lips to his, ignoring the rattling of the former human queen beside you. You adjusted yourself, so you were straddling his lap. You opened your mouth for him, and he accepted. His hand gripped your ass as your kisses became tongues and teeth clashing. You forgot what this felt like. To be held to be kissed with such passion.
To simply be wanted.
"My Queen of Darkness." He murmured, threading his fingers through your hair, "You don't even know how powerful you are." He yanked your hair, and you moaned. "I'll show you." He bit down on the tender flesh connecting your collar bone to your neck, and you moan as his hand gripped your breast. "You magnificent creature." You smiled at the sky.
This is what being worshipped felt like.
Snap
Koschei paused, removing his hand from your pert nipple he slide his hand to the back of your neck. Love and adoration in his eyes, lips swollen, "Tell me, as you are to me my bride. What gift shall I get you for our ceremony?"
What did you want?
You smiled Koschei, noticing the mischievous glint in your eye. "The General of the Night Court's Armies and his Little Lady of Death here chained like the dogs they are."
Koschei brought your face down to his. His mouth lingering over yours, "Anything for my Cruel, Beautiful, Mate." The gold thread wrapped around your heart tying you to him as he crashed your lips onto him.
Not even caring that Vassa had broken free from her cage and soared to the Human Realms.
To be continued?
