"Do you have all the preparations? Did you order the dark chocolate?"

Tyrus sighs, before turning to you. "Father/Mom, can't you make Mother stop fretting over this?"

You chuckle at your seventeen-year-old adoptive son. "She wants to make sure your seventeenth birthday is perfect."

The mention of the event makes Anna hug Tyrus. "My little vampire prince is growing up."

"Mother, I'm immortal. I can't grow up," Tyrus says, although he enjoys the attention. "Father/Mom turned me into a vampire a few days ago."

Even though he was still technically sixteen, as it was a few days before his seventeenth birthday; when you turned him, you were all celebrating Tyrus' seventeenth birthday.

"I know, but it seems like just yesterday you were a three-year-old," Anna answers her son.

Soon, you are in the ballroom, standing with Tyrus, Anna, Kristoff, and Elsa.

"The monarchs of Arendelle!" Kai announces. The guests bow and curtsy, and then applaud.

Soon, the room is filled with dancing and festivities. You turn to Anna, and then offer her your hand.

"May I have this dance, Your Highness?" you ask, before winking at her.

Anna giggles, and takes your hand. You walk onto the ballroom floor, and sweep her into an effortless waltz. Anna's light, happy laughter greets the air.

Tyrus smiles at you two.

Soon, he glances over; and is surprised to find a sixteen-year-old girl with green eyes, and black hair, standing across the room. She is wearing a black dress, and she has red highlights in her hair.

Tyrus can tell that she is a vampire.

He brushes his platinum blond hair out of his face, before walking across the room, toward the girl. He stands next to her, before stating. "Hello, I'm Tyrus."

The girl turns to him, before curtsying. "Prince Tyrus of Arendelle! It is an honor."

Tyrus chuckles. "Don't start with the formalities. Just call me Tyrus."

"What do you think you're doing?" a voice asks the adopted Crown Prince.

Tyrus turns toward the voice. It belongs to a seventeen-year-old boy with black hair, and black eyes. White highlights adorn his black hair. He is dressed in a black suit with a blood-red tie. A scarlet cloak completes the attire.

"Who do you think you are, addressing me in such a fashion?" Tyrus asks, in return.

"Who are you?" the opposing boy asks.

"Prince Tyrus of Arendelle," Tyrus answers. "My parents are Crown Princess, Anna of Arendelle, and Lord/Lady Y/N of Arendelle."

"Ah, the adopted vampire prince," the boy says. "I am Alexander, and that girl you're staring at is Cleo, my girlfriend."

The girl, Cleo, cringes at the argument.

"I did not mean anything," Tyrus says. "I was merely trying to start a conversation."

"That's right, Alexander," Cleo states. Tyrus turns to her, slightly, surprised that she's standing up for him.

Alexander narrows his eyes at Tyrus, before stating. "Alright, but I'll be watching you, Your Royal Highness."

"For the love of Dakhanavar, what was his problem?" Tyrus turns to Cleo.

"Alexander hates it when people flirt with me," Cleo answers.

Tyrus nods in confirmation, before turning to the table behind him. He fills two wine glasses with AB-negative, before handing a glass to Cleo. She, appreciatively, takes the glass, and then takes a sip.

"Mmm...AB-negative. My favorite," the vampire says.

"I never meant to make him angry." Tyrus takes a drink of his blood. "I just wanted to talk with you."

"I understand," Cleo says, with a smile. "Are there many vampires in the royal family?"

Tyrus shakes his head. "No, my adoptive mother/father, Y/N, was the first vampire. He/she saved Princess Anna, and then they fell in love, and after the Vampire Rebellion of Arendelle, they adopted me."

"So, your other adopted family members are human?" Cleo inquires.

"Yep. Aunt Elsa and Uncle Kristoff are human," Tyrus says. "There's also an enchanted snowman in the family."

"An enchanted snowman?" Cleo asks, laughing slightly.

"Yeah," Tyrus says. "His name's Olaf."

As if on cue, the tiny snowman bounds up to them. "Hi there, Tyrus!"

"Hi, Olaf," Tyrus greets the snowman with a smile. "This is Cleo."

Cleo waves to the snowman, who giggles in return.

After a while, a slow waltz begins to play. Tyrus watches as people select partners, and walk onto the dance floor.

Tyrus bows slightly to Cleo, and outstretches his hand. She chuckles, and takes his hand. The two begin to dance to the music.

Alexander is watching, jealously.

"You meant nothing, didn't you?" he whispers in Tyrus' direction.

Tyrus looks up, slightly glaring at Alexander.

'I'm just trying to be a gentleman, and he's trying to put the worst face on it,' the vampire prince thinks to himself.

From the other side of the ballroom, you and Anna watch your son, smiling contentedly.
