Vampires are, at essence, vicious killers. They need their clan and their mate to make them productive members of society but it is the truth that they are still the things of childhood nightmares and a rogue vampire is an unstoppable force. Vampires are slaves to their emotions and none more so than the Blood Princes, the Royal House of the Drăculești. Born of Royal and war-darkened blood they are warriors, cunning and ruthless. They are all powerful and another reason why some would eradicate vampires completely; a feat never successfully undertaken. A Drăculești threatened is a vicious behemoth and threatening one's mate is as good as committing suicide.

Kurt had never felt so light in his life. California was beautiful, Cooper was hilarious and fun to be around, Annalei was a great compliment to him and was becoming a great friend and he and Rachel were getting into everything they could, even if it made Blaine roll his eyes and more than once Duarte had sat them down and warned them not everyone was so friendly and happy powerful vampires like them were running around. He and Blaine were having fun, enjoying their time together and bonding with Cooper, even if his mate did get a little intense at times and Kurt noticed a slight change in his behaviour, he guessed it was being around Cooper but so far from his home and the rest of the family, it didn't matter to him if it didn't hurt anyone.

Cooper and Annalei showed them around LA. They took in shows, learned how to surf and spent time with their clan. Cooper turned out to be a great friend and they spent time together bonding and sharing stories of Blaine when he was younger.

Blaine caught his hand as he walked down the hallway on their third day there and tugged him with him out of the house, down across the cooling sand to the little boardwalk over the ocean behind Cooper and Annalei's house. The sun was setting, painting the sky gold, purple, red and blue and his vampire eyes watered at the sight that would have rendered him breathless with human eyes, but it was so much more with his clearer view.

They stopped at the end and Blaine turned around, his golden eyes sparking with happiness and love, lit up by the setting sun.

“Blaine?” Kurt asked, feeling his love's nerves and his breath hitching with anticipation.

Blaine stepped forward and placed his finger against his lips, shushing him gently then chased the finger with his lips after he removed it, kissing him slowly and sweetly. They parted and Blaine sank to one knee, looking up at him with adoration. “Kurt, you are my everything. I've been blessed by fate with a soul mate loving, caring, so open-hearted, so eager to be every part of my life and love my family. You've brought me happiness and brought my brother back to my family, saving him and loving him. You're my best friend, my mate, the man of my dreams and the man I can't wait to sound forever with. So, Kurt, my love, my mate, my soul, my heart. Will you marry me?”

Kurt stared at him as he brought out a box from his pocket and opened it to reveal a sparkling platinum ring dusted in tiny diamonds, sapphires, rubies and emeralds. His tears spilled over and for a fraction of a second Blaine looked scared but Kurt nodded quickly, forcing himself to speak through his choked up throat. “Yes. Yes, I will.”

A grin spread wide over Blaine's face and he stood to kiss Kurt deeply then slid the ring onto his finger, a perfect fit. Kurt held it up to the fading light, watching it shine before he heard whoops and looked away to see Cooper, Annalei and Rachel running down the beach at them. Kurt and Blaine looked at each other, unspoken mischief passing between them and they bolted back up the boardwalk and across the beach, away from the others.

They all spent the next hour chasing each other around, cool sand under their feet and laughter in the air.

The days passed and Kurt watched Blaine change into someone he wasn't sure of half the time. Sometimes he'd be the same loving boy he was then there'd be a spark of intensity and Blaine would change. Sometimes he'd be angry, sometimes passionate, sometimes overly happy; sometimes sadness would creep through him and leave them both gasping for air.

He didn't question it, just rolled with it; assuming that the separation from his parents that everyone had mentioned was hard on Blaine and making him act out. He never questioned it, or saw the shadow that slipped into the kitchen and the darkness that swirled into his mate's blood.

Cooper watched his brother from the doorway as he and Rachel talked over Rachel's plans for college and Broadway. Blaine was making grander and grander gestures, drawing fond glances from Kurt who was reading on the window seat but Cooper was worried. “Duarte.” He called softly and the other vampire was by his side in a second.

“My liege?”

“Check out our blood supplies and keep an eye on them and our trio there, would you?” Cooper asked, not taking his eyes off of his brother.

Duarte tilted his head minutely. “What are your thoughts?”

Cooper sighed and looked at the guard. “I am just worried about our piccolo erede.”

Duarte bowed his head and replied. “Leave it with me.”

Rachel giggled loudly and Cooper smiled and walked into the room. “What are you three hellions up to?” He said jokingly and earned an eye roll from Blaine.

“We're going to a club.” Rachel said, bouncing on her toes and clapping her hands.

“A club?” Cooper said doubtfully.

Blaine nodded. “Yes. We want to go out dancing and we haven't seen much of the nightlife. Any recommendations?” He asked, his voice decisive and dark.

Cooper nodded slowly. If they were going out he could at least make sure they were safe and knowing his brother and the way he was speaking, he couldn't talk them out of it. “I'd suggest Club Rain. It's for the under 21's and it's a fun place.”

“Ooh let's go there.” Rachel said, turning to Blaine who nodded.

“Kurt?” Cooper called. Kurt looked over at him, questioningly. “Can I have a word?”

Kurt nodded and got up to walk over, kissing Blaine's cheek on the way. The black-haired vampire watched Kurt the whole time and his intense stare scared Cooper slightly. When they were out of the room and out of Blaine's hearing range Kurt turned to him. “What do you need, Cooper?”

Cooper sighed. “Do you really want to do out clubbing?”

Kurt nodded, glancing back towards the room. “Yes, I do. I've never been to one and I don't know if I'll ever go to one again. It would be nice to. Plus, Rachel and Blaine want to go.”

Cooper leant against the wall and rubbed a hand over his face before he spoke. “Ok. You guys want to go and I can't stop you but I know you see how Blaine's been as much as I do and I want you guys to be safe. Please, please just keep yourself and them safe, follow anything Duarte or any of the other guards say and keep an eye on him,” Kurt nodded and started to leave but Cooper grabbed his arm. “And stay safe yourself.”

“Ok.” Kurt whispered and walked away.

Cooper had never seen Duarte scared and he was pretty sure no-one else had before. “Duarte, what is it?”

“Where's the Prince?” He asked, his voice pitching with panic.

“He's about to leave with Kurt and Rachel, what is it?” Cooper asked, following Duarte as the man strode down the corridor.

“But where is he?”

“The kitchen.” Cooper said and had to break into a run as the hulking vampire's eyes widened with horror and he bolted through the corridors to the kitchen.

They got to the doorway and Duarte almost flung himself through it. The Prince was standing there, a bottle of blood raised to his lips. “No, don't!” He shouted reaching out to stop him but it was too late. Blaine gulped down the last of the blood, gave them a strange look and was gone before they could blink.

“What has gotten into you Duarte?” Cooper asked, grabbing the man as he slumped against the doorframe.

“You asked me to check the blood supplies your Highness,” He gasped out. “The others are clean but the ones earmarked for Prince Blaine, they were wrong.”

“What?” Cooper shrieked.

“He's being drugged.” Duarte replied and the two vampires ran out of the door, hoping to catch the three teens before something bad happened.

“Tell me about this drug.” Cooper demanded as he drove out to the club Kurt, Blaine and Rachel were going to.

“It's a very dangerous drug. It was meant to increase fitness in humans before they banned it. In vampires it can cause erratic behaviour, wild mood swings-“

“So it's turned my brother hormonal, lovely.” Cooper gritted out.

Duarte shook his head. “It's more then that your Highness.”

Cooper glanced at him. “Then what?” He asked.

“Prince Blaine has been changing, we've all seen it but with enough of it in his system he forgets who he is and who we are and what he cares about.”

“So you're saying?”

“Having the chance, Prince Blaine would kill us all without a care.”

The music was pounding through his veins, the lights flashing even behind his eyelids, changing colours with the beat. The pressure of Blaine behind him, his strong arms wrapped around his waist and them moving as one to the beat sent sparks rushing through him, making him dizzy. They'd lost Rachel in the crowd a while ago but he'd seen a guard following her so wasn't too worried. Right now all he could feel was Blaine against him, his lips drifting over his neck making him feel like he was flying. Until he needed to pee, of course. “Blaine,” He called and the other vampire just hummed against his neck. “Blaine I need to go pee.”

Blaine chuckled and span him around so they were front to front. “Ok my Prince, you go pee. I'll be right here when you come back.”

“I won't be long.” Kurt replied and they kissed for a second then Kurt went off in the direction of the toilets.

The door slammed open and Kurt sighed. He couldn't exactly ask for clean bathrooms at a club but the smell was disgusting. He held his breath and walked over to one of the stalls, quickly locking it and peeing, not wanting to use the urinal and someone seeing him pee made him shudder. He finished up and went out to wash his hands. As he was rinsing the door opened and a tall blond vampire walked in. He looked back at the sink as the other vampire checked him out before the man staggered over to the urinal to pee. The stench worsened and Kurt crinkled his nose. He dried off and was about to walk out when the vampire walked over to the sink and spoke.

“Hey, haven't seen you around before. New around here?”

Kurt nearly rolled his eyes. Oh my gosh such a cheesy line. He looked at the blond and smiled politely. “Yeah, just on a vacation.” He gripped the door handle and was about to leave but as the vampire spoke again his politeness kicked in.

“Oh yeah? From where?”

“Ohio.”

The vampire shook his hands, sending droplets everywhere. “Oh yeah? That's where the royal family are living right now I heard.”

Kurt nodded, glancing to the side. “So I hear.”

“Ever seen any of them?”

Kurt almost smirked, thinking. ‘Yeah I just had one kissing my neck, wanna meet him and his overprotectiveness?' “I have to get back.” He replied, knowing Blaine would come looking for him soon and was slightly worried; in his state he could do anything.

The blond vampire didn't seem deterred and strode over, placing his hand on the door. “Hey, we're just chatting. Why don't we go into one of those stalls? Make it something more?”

Kurt bristled and replied coolly. “I don't think so. I have a fiancé.”

The vampire shrugged. “So? He never has to know.”

“No.” Kurt said and wrenched the door open but didn't throw the other vampire off balance. He walked along the wall, hoping to either get to the doorway and get a better vantage point for him to find either Blaine or Rachel or get some signal on his phone. The vampire followed him, however and didn't want to give up.

“Come on dude, just a little fun.”

“No, get away from me.” Kurt replied icily, trying to look for his mate and get away from tall, blond and stupid at the same time.

The other vampire's eyes turned hard. “Ok, I've had enough games, come on.” He grabbed Kurt's arm and hand a hand over his moth before he could call out, dragging him out of the club and into the dark street. Kurt tried to push him off but the other vampire was stronger and Kurt felt weak, probably one of his powers. He was dragged into the alleyway and pushed against the wall. The vampire took his hand off of his mouth and raised his fist. “I wouldn't do that if I were you.” Kurt said lowly.

The other vampire snorted. “Oh? Because you're going to beat me off?”

Kurt shook his head. “Not me.” He glanced over the other vampire's shoulder and almost gasped. He'd felt his mate's presence but the man who stood on the other side of his would-be attacker was someone Kurt had never seen before. It was Blaine but not a Blaine Kurt had ever seen. His eyes were jet black, his skin cracked and darker than usual and he looked like he was on fire, his fury coming off him in waves.

“Me.” Blaine growled and launched forward, grabbing the other man by the neck and wrenching him off, a loud crack punched through the air as the blond was thrown across the alleyway. He got back up and roared but Blaine was faster and barrelled through him.

“Blaine that's enough!” Kurt shouted and took a step backwards, his hand flying to his mouth as he looked at the blond vampire. He was missing part of the right side of his torso but he carried on coming and Blaine prepared to attack again. An arm flew through the air and Kurt bolted out of the alley.

A car screeched to a stop beside him and he almost cried with relief. Cooper and Duarte were inside with Rachel and her guard in the backseats. “Where's Blaine?” Cooper asked and Kurt pointed back to the alley where a scream pierced the air.

“Someone tried to attack me and Blaine's killing him!” He screamed.

Cooper's eyes widened and he got out. “Kurt get in. Duarte drive them back to the house and don't let anyone in or out, got me?”

“Perfectly.” Duarte intoned.

“Cooper you can't, he might kill you too.” Kurt cried out and Cooper pushed him into the seat he'd vacated.

“I'll be fine. Go.”

“What's happening to him?” Kurt asked as they sped down the streets. He was shaking; the images of the man with blood and body bits on the floor wouldn't leave his mind.

“He's been drugged. Someone was spiking his blood supply.” Duarte replied.

Kurt closed his eyes and tears rolled down his cheeks. Suddenly the car stopped and Duarte put his hand on Kurt's shoulder. Kurt looked at him and the other vampire spoke, his voice shaking slightly.

“Kurt? When Cooper and I left the lights were all off.” He said and Kurt opened his eyes. The house before them was lit up, every room blazing with light.

“Is Annalei home?” Rachel asked from the backseat.

Duarte shook his head. “No. She's sleeping at her mother's. For protection.”

“And she couldn't have come home?” Kurt asked.

Duarte shook his head again. “It's not her inside.”

Kurt looked over at the house and sighed, looking at his hands as he flexed them. “Maybe I can calm him down.”

“Kurt you can't go in there!” Rachel cried.

“Rachel he needs me,” Kurt replied and got out before anyone could stop him. The front door opened and a figure stood in the doorway. Kurt walked up the steps, praying for it to be Cooper or his wife but as he got closer he saw the unmistakable stature of his fiancé and his scent. “Blaine?”

“Hi honey,” Blaine replied, growling. “I missed you.”

“Blaine,” Kurt breathed, shutting the door behind him. He took a tentative step forward, his hands raised in defence. “Thank you for saving me but you need to calm down. You've been drugged. This isn't you.”

“Funny. I feel fine.” Blaine growled back and Kurt felt the calming waves he was trying to send to Blaine get shoved back into his own body, stunning him. Blaine grabbed his wrist and dragged him down the hallway to the bedroom they were using.

“Blaine wait. What are you doing?” Kurt asked, fear setting into him. Blaine didn't answer, just dragged him in, shutting the door and slammed Kurt back up against it. The drugged vampire kissed him deeply, cutting his lip and tongue with his teeth, then turned him to face the door before Kurt could do anything. “Blaine stop, this isn't you!” Kurt shrieked and almost screamed when his pants and boxers were unceremoniously ripped off.

“I'll do what I want to you. You're mine.” Blaine growled and stepped away. Kurt took the chance to try to get away but Blaine's powers were holding him in place and he leant his forehead against the wood, tears slipping down his cheeks.

“Please Blaine.” He whimpered then screamed when he felt Blaine come back and two fingers slam into his hole, ripping skin, violating him and he remembered weeks ago when Blaine did this lovingly, them joking around but now everything had turned into a horrible nightmare. Kurt squeezed his eyes shut as the fingers slammed into him over and over then gasped as they ripped out of him. He tried to speak again but just screamed as he was thrown onto the bed. Blaine climbed on top of him, his pants open. Kurt tried to push his powers out again to stop or at least calm the terrifying vestige of his mate but Blaine pressed him into the mattress in retaliation, licking his neck. “Please Blaine, stop this,” Kurt whimpered again and Blaine sank his teeth him, his cock pressing determinedly at Kurt's hole. Kurt sobbed then gathered his thoughts, realising giving in could be the thing to save him. He touched Blaine's cheek and waited for him to let go. Blaine finally detached himself from Kurt's neck and looked at him. His eyes were still black and glassed over, the terrifying eyes of a killer but Kurt hoped his mate, the sweet boy who talked of wolves' howls and called him beautiful the night they met was still in there somewhere. “I love you Blaine. I forgive you.”

Blaine blinked and Kurt held his breath but a wide, savage grin spread across his mate's face and Kurt closed his eyes as he felt the growl rumble against his chest. “Good.”
