Things settled down after that and Kurt slipped into gentle, easy life with Blaine back to his loving, adoring self, dealing with day to day royal life and training Finn to protect them as well as getting to know his cousin.
Blaine's family came around more now and Kurt got to know Blaine's cousins. He bonded with most but especially Anni whose father ruled the Asian continent clans and was relieved to find the pyro wasn't as scary as Blaine had made her seem. She'd giggled when Kurt told her about Blaine telling him the incident with the liner. She'd nudged him and replied that Blaine had forgotten to tell him that she'd only been around nine. Blaine had become the victim of their pranks for the time she'd spent at the manor with them lighting the edges of the trench coat he'd taken a liking to alight or sending him feelings, one after the other until he chased them down the hallway, usually ending with him locking Anni out and taking Kurt to their wing and throwing him onto the bed to ‘punish' him.
The plans for their wedding went forward too and the press were having fun chasing Kurt and Katarin all over town when they went to look for things to buy.

Kurt was studying what colours would go with the traditional black suits when he heard Blaine's father call him. He walked into the library and was slightly shocked to see the Count, Countess, Blaine, Cooper and their parents there. “What's going on?” He asked warily. He didn't like being kept out of the loop on things and after the disastrous California trip he and Blaine had reaffirmed their promise to be honest about everything that they'd made when they met.
“Kurt, I'm sorry, we didn't want to keep you in the dark and we've had long lectures from Blaine about forcing him to not say anything to you,” Dmitri spoke and Kurt glanced at his mate to see him looking tensely at his father then the look soften into a plea for forgiveness when he looked at Kurt. “We know you're busy planning the wedding so we wanted to keep this burden off you but as you know we move around, spending time where we want and need to go and the time has come for us to move again.”
Kurt gives him an unimpressed look. Blaine gets his dramatics from the older vampire and Kurt can't see why he would keep quiet on something as silly as moving. “That's all? I thought it was some big problem or something.”
Dmitri holds his hands up in defence when Blaine growls. “Told you so. Tell him where to.” And sighs.
“I am sorry, Kurt. We are moving to New York.”
Kurt's eyes widen and his mind buzzes with excitement. New York. He'd dreamed of it back when he was in school, taking on Broadway with Rachel and making the city his but after mating with Blaine his life plan had changed and Broadway was impossible, his life was so much more now. “Are you serious? New York?” He shrieks and Blaine walks over to wrap him in his arms. Kurt leaps into them excitedly and the older vampires laugh.
“You are happy then, I take it?” The Count quips and Blaine answers for him as he's hiding his face in Blaine's neck, muffling his excited screams.
“He's dreamed of New York since he knew it existed.” 
The others file out, knowing when they need to leave the couple alone. Kurt finally leaves the crook of his mate's tanned neck and grins at him. “New York, Blaine! I can't believe it. We can do so much there!” He screams and Blaine cuddles him harder.
“We can. I've always wanted to go back there and we can be close to Rachel and New York has so much more than Lima.” His black-haired mate replies and Kurt can see adoration colouring his deep honey eyes.
“You…Wait you planned this?” Kurt gasps, putting two and two together.
A proud ‘look what I did' smile spreads over his mate's face and he nods eagerly. “They asked where I wanted to live and I said New York. I love you so much.”
Tears fill his eyes and he leans his forehead against Blaine's. “I love you too. Best fiancé ever.” He breathes and their lips meet in a deep kiss.

Christmas wasn't a big deal for vampires but as their bi-monthly ball landed in December and it was the first one since the Princes got engaged that they were able to attend, along with the announcement that the Royal Family were moving to New York, made for a big celebration that most of the Council and their families would be at.
“High Prince Kurt Amorsa and High Prince Blaine Anderson.” The attendant called out and Kurt gave him a wink before they descended which had the man stifling a laugh.
“What was that?” Blaine asked with a smile and Kurt shook his head, laughing. 
“The night we met I made a joke that he didn't call me ‘just a human' when he announced Rachel and I.”
“Oh.” Blaine replied and chuckled. They got to the bottom and nodded regally when the guests bowed to them. They walked to the centre of the dance floor, the guests parting in front of them and started gliding around to Natalie Imbruglia's Hurricane.
When the song finished Kurt felt a hand grip his wrist and he turned to see Rachel beaming at them.
“Rachel! You came!” He exclaimed and hugged her tight.
Blaine touched his shoulder and whispered. “I think I'll leave you two to catch up. I'll go save Annalei's feet from Cooper's two left ones.” He hugged Rachel, kissed Kurt's cheek and left with a whirl of his cape.
Kurt and Rachel started dancing, grinning wide at each other. “I couldn't miss it, Kurt. It's your engagement ball! Speaking of…” She trailed off to look at the ring he made sure was on prominent display, catching the light and many admiring looks.
Kurt giggled and flashed it. “Oh this thing? You know Blaine had it made for me.”
“Oh my gosh!” She gasped. “I can't wait to meet my mate.” She said wistfully and looked around.
“You know we're moving to New York in two weeks?” Kurt asked, catching her attention and she grinned at him again.
“Yes! We're going to have so much fun!” She squealed, bouncing and almost tripping them both. She quavered slightly under the glare of Blaine's great uncle Danii until he looked over at Kurt and smiled. When he'd moved away Rachel leaned close and whispered. “Do you have that effect on all of Blaine's family?”
Kurt grinned and shrugged. “Hey, I'm adorable and clearly the most awesome person here, aside from Blaine,” He glanced around and they giggled. “So, tell me about NYADA.”
Rachel sighed and flicked her hair but her eyes sparked with happiness. “It's gruelling, my dance instructor is a self-righteous know it all who has an ego even though she bombed out of Broadway decades ago and her main power? She's a succubus. A succubus, Kurt! Ugh.”
“Sounds like hell.” Kurt commiserated and made a note to ask Blaine why succubae were so bad.
“Yeah but it's so worth it. I love it so much, Kurt. It's New York and my dream and the city is beautiful and I love my apartment. I miss my dads who are over talking to your dad by the way and I've learned so much more than I ever did at school and I'm going to be on Broadway!” She said in a breathless rush as he twirled her.

Kurt smiled. Long ago he would've been there with her, or listening to her when she came back if he hadn't got in. Maybe he would've gone into fashion instead but that wasn't his dream anymore. He looked over at Blaine who was laughing with Annalei, admiring him from afar. He was wearing a black suit with silk lapels, silver lining to match his with gold lining.
“What about you?” Rachel's voice filtered through him checking out his mate's ass and he blushed.
“I don't think I knew what happy was before, Rachel. It's like a light was turned on and everything is shinier, better. I can't wait for the rest of my eternity by Blaine's side. Oh, do you like our suits? I made them.”
“Oh wow, I love them. Are you making your wedding suits?” She asked.
Kurt shrugged. “I don't know. Maybe but they have to be a certain way. The Count told me about traditional attire and he might ask Blaine to wear his grandfather Valerian's suit.”
“Oh wow that would be amazing.” Rachel replied and Kurt nodded.
“Excuse me,” A deep voice spoke and they turned to see Blaine. “I hope I'm not interrupting you two plotting to take over the world.” Blaine joked.
Kurt smirked back at him, going into his arms when his mate took his arm. “Oh honey, I'd only ever do that with you.”
They kissed and Rachel mock-huffed. “Oh Kurt have you been leading me on?”
“Deal with it.” Kurt shot back and Blaine snorted.
“Well if you two are done, I have someone I want you to meet, Rachel. This is Finn, Kurt's cousin.” Blaine said, gesturing to Finn who came into view.
Rachel's mouth dropped open and she felt ready to faint. Finn stared at her and it felt as if he was looking into her soul, every fibre of her screaming ‘mate, mine'. “Finn.” She said in a whisper.
“Rachel.” He whispered back and Kurt looked between his friend and his cousin then leaned into Blaine.
“Uhh, is that what we looked like?”
“Just about. Come, beautiful. Let's leave them alone and enjoy our night.” Blaine replied and they took each other's waists, dancing away.

Cooper watched his brother and Kurt across the floor and sighed. They were chatting and nuzzling each other, enjoying the little bubble that surrounded them as they drifted in their own world.
“It is beautiful, is it not?”
Cooper startled at his mother's voice and glanced at her, then back to the couple. “I wish I could've been here when they met.” He said regretfully.
“But you're here now. That's all that matters.” His mother replied and walked away.
He watched her leave then smiled as the couple kissed and thought of the many, many years he had to watch them dance and share their love.

Dmitri stepped onto the stairs, walking up a few and nodded at the attendant. He'd been thinking about this for weeks. Blaine was old enough; mature enough and recently he'd seen more of the Blood Prince his son was destined to be. He could see it, the future of the Council, their clans, with his son and Kurt ruling. The boys had taken on more and more responsibility since they'd met, the last time they were all gathered here at once, and then even more since they'd come back from California. His Grandfather and uncles' plan to have them confront the Despoina had worked and as he looked at the budding mates in the corner he smiled. Kurt had gotten a cousin, uncle and grandfather they all had yet to meet out of it. Their family would thrive, their clans would prosper and with the join of the Dănești and Drăculești, the prophecy calling the union of the sons of the Basarab the beginning of a strong and happy rule would come true.
“His Supreme Highness Dark Prince Dmitri Vlad Anderson!” The attendant boomed and everyone stopped, turning to him and he searched out his wife who smiled at him reassuringly and his son and soon-to-be son in law who were watching him curiously.
Dmitri took a deep breath and called out, letting his voice fill the room. “Thank you all for coming to our ball this evening. As you all know this is a special time for us, with our Prince Blaine and Prince Kurt's engagement and before long union, Prince Cooper and Princess Annalei's coming home, our relocation to New York and Christmas we have had many things to rejoice this year. I have been at the head of the American clans for almost three hundred years and in that time I have seen the world change but no more so than these last few years and I have decided to step down from my role as Blood Prince in the coming year and will be relinquishing rule to my son His Highness Prince Blaine Diavolo Anderson and my son in law His Highness Prince Kurt Dan Amorsa. I fully believe that with them ruling we will continue to be happy and flourish as a family, empire and society.” His announcement was met with gasps and shocked silence then thunderous applause. He looked over at his son and Kurt who were now staring at him wide-eyed.
“Did you know he was going to do that?” Kurt hissed and Blaine shook his head, then as his father went and sat down on his throne, looking tired he grabbed Kurt's hand and walked over to the older vampire.
“Follow my lead,” He whispered then stopped in front of his parents who stood up. He dropped to one knee, feeling Kurt copy him and the eyes of their guests on them. He bowed his head and spoke. “I accept your decree, my father, my liege and pledge to be as powerful and just a leader as you have been.” He stood when his father asked him to and felt him and his mother draw him and his mate into their arms.
“I love you, my sons.” His father whispered.
“We love you too.”
