As constant as a star,
Sure as the dawn brings the sunrise
We have an unshakeable bond

 


 

 

Once upon a time, in a land where winter’s breath lingered all year long, there stood the Great Northern Empire.

A realm of vast landscapes and ancient traditions, where the cold was not just a season but a way of life. The empire’s lands were covered in endless forests, frosted plains, and rivers that froze solid in the heart of winter. The people here were resilient, strong and proud, shaped by the harsh winters that seemed to last forever. Finding warmth not only in their heavy fur cloaks but also in their faith, family, and the wisdom passed down through the legacy of their rulers—the Tsars, who for generations had guided them with strength and wisdom.

The Winter Palace of the Great Northern Empire, where the Royal Family lived, stood proudly on the banks of the mighty River Neva. It was connected to the city by a grand road, known as the Tsar’s Way, lined with towering pines, their evergreen branches creating a natural archway that seemed to guide visitors directly to the palace's gates.

And despite its distance from the city, the Winter Palace maintained a watchful presence over it.

From its balconies and grand halls, one could gaze out across the icy expanse of the Neva, where the city’s skyline—dominated by the spires and domes of cathedrals—lay in perfect view. In winter, the river froze and connected the palace to the city not just by road, but by nature’s own design. This represented the Tsar’s authority, overseeing everything that the view could reach and beyond. The river Neva, flowing steadily past the palace, was a reminder of the empire’s lifeblood—constant, powerful, and unyielding, just like the winter that defined this land.

The latest to ascend the throne was Tsar Ivan Nikiforov, a beloved ruler whose presence was like a ray of sunlight breaking through the harshest storms. Under his reign, the empire had flourished. But as with all things in this world, the light of Tsar Ivan's reign was not to last forever. When he passed away unexpectedly, the kingdom was cast into a shadow of mourning so deep that even the stars above seemed to dim in sorrow.

Left behind was his widow, the young Empress Elena. She had loved her husband dearly, and his death left an ache in her heart that everyone knew it will not fully heal. Yet, duty called her to rise above her grief, for there was still much to be done. She was now the regent of the this Empire, charged with guiding the kingdom until her young son was old enough to take the throne.

His name was Viktor, the Tsesarevich, Imperial Grand Prince.

Tsesarevich Viktor was a child of winter, born under the glowing lights of the aurora borealis, which danced across the sky on the night of his birth. People believed he was destined for greatness, that the very spirit of winter had blessed him with its grace and power. But he was still just a boy, innocent and unburdened by the weight of the crown that would one day rest upon his head.

Empress Elena knew that time was not on their side. The Great Northern Empire, vast and mighty as it was, could not stand alone. The death of the Tsar had left a void, not just in the hearts of the people, but also in the alliances that kept the empire secure. Neighboring nations watched with keen interest—some with envy, others with fear. So, when an invitation came from the East Sun Empire, the Empress saw it as an opportunity—a chance to forge a bond that could secure her son’s future and the future of the empire.

The East Sun Empire was a kingdom of serenity and grace, where cherry blossoms never stopped blooming, even as snow fell heavily in the Great Northern Empire. This land was one of ancient traditions, where every detail of life was infused with a sense of harmony and balance. The people of the East Sun Empire were known for their art, poetry, and deep spiritual connection to nature, with rituals and festivals that celebrated the turning of the seasons and the spirits that inhabited their world.

“We must look beyond the snows.” Elena had decided, her voice firm as she spoke to Yakov, her brother-in-law and the late Tsar’s most trusted advisor. “Vitya needs to see that the world is not only ice and snow. He must understand that our Empire, though great, does not stand alone.”

Yakov, a man as stern as the granite cliffs that bordered the Empire’s northern reaches, had nodded in agreement. He understood the importance of this journey, not just for the Empire, but for the boy who would one day lead it. 

“It will be good for him,” Yakov had conceded. “He must learn that there is more to this world than what lies within our borders. And the East Sun Kingdom is a worthy ally.”

And so, the decision was made. Preparations began immediately as the harshest time of winter was fast approaching an they must part before the first storm. As the day of departure approached, little Viktor, sensing the excitement in the air, grew curious. He followed his mother from room to room, his bright blue eyes wide as he watched the servants hurrying through the halls, packing trunks for the long journey.

“Mama, where are we going?” he asked one evening, his small voice filled with the innocent curiosity of a child.

Elena, kneeling down to his level, smiled gently and brushed a lock of silver hair from his forehead. “We are going on an adventure, my love,” she replied, her voice warm and reassuring. “To a place where the sun always shines, and the flowers bloom even in winter. You will see many new things.”

Viktor’s eyes lit up.

“Will it be warm there, Mama?” He asked, a hopeful note in his voice.

“Yes, my dear. It will be warm, and you will not have to wear your heavy furs all the time,” Elena answered, a playful smile tugging at her lips. “But you must promise to be on your best behavior. This is a very important trip for both of us.”

Viktor, though young, sensed the seriousness in his mother’s tone. He nodded solemnly, his small hand reaching out to grasp hers.

“I will, Mama. I promise.”

 


 

The journey from the icy expanses of the Great Northern Empire to the shores of the East Sun Empire was long. But as they neared their destination, the world began to change around them. The air grew warmer, the skies brighter, and the land itself seemed to come alive with color and light.

Finally, after countless days of travel, they arrived at the borders of the East Sun Empire.

The guards, dressed in the bright, flowing robes of their kingdom, greeted them smiling. The difference between the two kingdoms was big—where the Northern Empire was a land of restraint and order, the East Sun Empire was a realm of color and joy, its people welcoming and full of life.

But it was the palace that truly was a breathtaking sight.

Rising majestically at the heart of the city, its walls were adorned with carvings of dragons and phoenixes, symbols of power and rebirth. The architecture was simple yet elegant, with wooden beams polished to a deep sheen and roofs curved gracefully like the wings of a bird. The gardens were a paradise of blooming flowers and flowing streams, where koi fish swam lazily in the ponds, and stone lanterns cast a soft glow at dusk. The scent of jasmine and lotus blossoms filled the air, mingling with the sound of birdsong and the distant hum of life within the palace walls. As the carriage came to a stop, the doors were opened by attendants dressed in robes of deep red and gold. The Royal travelers were greeted by a courtiers, all of whom bowed deeply as the Empress stepped out onto the smooth marble steps.

At the top of the steps stood the Emperor of the East Sun Empire, a man of a mysterious smile, and beside him, his wife, the Empress Consort Hiroko.

“Welcome to the East Sun Empire, Empress Elena.” The Emperor said. “We are honored to have you as our guests.”

“The honor is ours, Your Majesties. We are grateful for your invitation and the kindness you have shown us.” Elena curtsied gracefully. 

The Empress Consort, her face soft with the glow, smiled down at Viktor. 

“And this must be the Tsesarevich.” She said, her voice gentle. “I hope you had a fun trip, Tsesarevich Viktor.” 

Viktor blushed under the Empress’s gaze and followed his mother’s lead, as he looked up. The boy bowed deeply, as he had been taught, his voice small but clear as he replied.

“Thank you, Your Majesty. I am honored to be here.” Little Vitya replied.

“I see that your son is as charming as he is well-behaved, Elena. You must be very proud.” Hiroko’s smile widened, and she exchanged a warm glance with Elena. 

Elena returned the smile, her heart swelling with pride. “He is my greatest joy.”

But the attention of young Prince Viktor was quickly drawn to something else— In the arms of the Empress Consort Hiroko was a tiny bundle, wrapped in silken blankets of the purest white. It was a baby. Viktor stared with wide eyes, his curiosity piqued. He had never seen a baby so small, so delicate - his cousin, Mila, born almost a year ago, looked definitely more chubby and rosy. 

As they approached, the Empress Consort leaned down, allowing Viktor to get a closer look.

“This is Prince Yuuri.” Hiroko said softly. “He was born just a few months ago. He has brought more joy to our lives than we could have ever imagined.

Viktor gazed at the baby, who blinked up at him with wide, curious eyes. Without thinking, he reached out a hand. To his surprise, the baby’s tiny fingers wrapped around his own. Viktor’s breath caught in his throat as he felt the warmth of that little hand, so small yet so strong.

“He’s holding my hand, Mama.” Viktor whispered, his voice filled with awe. It was as if he had just discovered the most wondrous thing in the world.

“Yes, Vitya. He likes you.” Empress Elena, who had been watching the exchange with a soft smile, nodded. 

The two Empresses exchanged a glance, a knowing look passing between them.

“It seems our children were destined to meet.” Hiroko said, her eyes twinkling with a hint of mischief. “Perhaps this is the beginning of a great friendship?”

Elena chuckled softly, her own heart warmed by the sight of her son holding hands with the baby prince. 

“Perhaps it is.” She agreed, though a part of her wondered if this meeting was the beginning of something even greater.

Emperor Toshiya, who had been observing with a thoughtful smile, decided to add his own playful twist to the moment. 

“Well, if they’re getting along this well already, maybe we should just marry them tomorrow and save ourselves the trouble later!” He joked, his deep laughter filling the room.

Hiroko playfully swatted her husband’s arm. “Toshiya, they’re just children!” She chided, though the sparkle in her eyes suggested she found the idea amusing.

“True, true,” Toshiya conceded with a wink. “But you have to admit, it wouldn’t be the worst idea. Imagine—our kingdoms united by these two little ones!”

Elena laughed, shaking her head at the emperor’s teasing. “Let’s give them a few more years, shall we? But who knows… Perhaps one day your jest will become a reality, Your Highness.”

“One day, perhaps.” Hiroko echoed, her voice carrying a note of hope. She looked down at the little Prince Yuuri, who was still holding Viktor’s finger, and then back at Empress Elena. 

And with that, the light-hearted banter faded into a comfortable silence as the two families watched the young prince and the newborn. As the adults returned to their conversation, Viktor remained where he was, captivated by the tiny hand holding his own. In that brief moment, the world outside the palace walls faded away, and all that remained was the warmth of a new friendship, as fragile and as beautiful as the first blossoms of spring.

 


 

The days turned into weeks, and the cold of the Great Northern Empire began to fade from Viktor’s memories, replaced by the vibrant warmth of the East Sun Empire. The palace grounds were a paradise of color and life, where the air was filled with birdsong and the fragrance of blossoms. Little Tsesarevich Viktor, at just four years old, had exchanged his thick winter furs for a light, feathery kimono of olive green silk. The delicate fabric flowed gently as he explored the vibrant gardens. A small obi sash held the kimono in place, and soft zori sandals replaced his heavy boots, allowing him to move with ease in this new world.

He spent his days marveling at the strange and wonderful plants that seemed to spring from the very earth. The servants, seeing his wide-eyed wonder, took pleasure in showing him the secrets of their land—the hidden groves where the rarest flowers bloomed, the serene ponds filled with koi.

Most of the time, if anyone were looking for young Tsesarevich Viktor, they would find him beside Prince Yuuri’s cradle. Though the baby was too young to play, he would sit beside the cradle or sometimes drag a wood chest and climb over it to see the baby, captivated by the way the baby Prince's tiny hands grasped at the air or how his wide eyes followed Viktor’s every movement. Sometimes, Yuuri would lock his gaze on Viktor, watching him and making the young Tsesarevich smile.

Viktor would gently rest his small hand on the blanket, his touch protective and tender.

“You’re safe with me...” He would whisper, his lips in a heart-shaped smile. “When you’re big like me, we’ll play together all day, building snowmans and sliding on the snow. We’ll always be together. I’ll keep you safe, I promise.”

And as he made this vow, the warmth of the East Sun Empire seeped into the little Prince’s heart, melting the cold that had settled there after his father’s death. 

 


 

In a quiet chamber Empress Consort Hiroko sat with her husband, Emperor Toshiya. They spoke in hushed tones, their voices carrying the weight of the conversation that had begun as mere fun, now taken on a life of its own in their minds.

“Our son is still so, so young,” Hiroko began, her gaze resting on the sleeping form of Prince Yuuri, who lay cradled in her arms. “But already, he has forged a bond with the Tsesarevich.”

Emperor Toshiya nodded thoughtfully, his eyes narrowing as he considered the implications of such a union.

“Indeed. But we must tread carefully. It would not be enough for them to be bound by duty alone. If a marriage between Yuuri and Grand Prince Viktor is to take place, it must be because they choose it—because they come to love each other.”

Hiroko’s lips curved into a gentle smile. “Love cannot be forced. If they are to grow close, it would be wise to let them spend time together, to let them learn each other’s hearts as they grow.”

“You are right, my Empress.” Toshiya agreed, reaching out to gently stroke the soft hair of his son. “But there is more to consider. Yuuri is not our heir. That burden belongs to our Mari, the Sun of our Empire. If Yuuri were to marry Viktor, he would leave the East Sun Empire and live in the Great Northern Empire, where the winters are harsh, and the nights are long.”

Hiroko’s expression grew thoughtful.

“Then we must prepare him for that life, I worry of him not adapting fully. If he is to thrive in the Northern Empire, he must come to know it, to feel at home there. Let him spend each summer in the Northern Empire, when the days are longest, and the cold is not so biting. It will ease the transition, should the day come when he must leave his homeland behind.”

The Emperor considered this, nodding slowly as the plan took shape in his mind. 

“Yes, each summer, he will visit the Great Northern Empire. There, he will be under the care of Empress Elena, and he will grow up alongside Viktor. In this way… Emperor Toshiya concluded, “They will have the freedom to choose their own paths. If they come to love one another, their union will be one of strength and harmony, blessed by both our peoples. And if not, they will part as great friends, with no ill will between our lands.”

“They will have the chance to choose their own destiny.” She murmured.

Hiroko’s heart swelled with hope as she looked down at her son, the Moon of their Empire.

 


 

The decision was made with the wisdom of rulers who understood not only the balance of power but also the fragile nature of the human heart. It was agreed that the two young princes would spend each summer together, allowing their bond to grow naturally, free from the pressures of court and the burdens of expectation.

Thus, a plan both simple and profound took shape. The young Prince Yuuri, the Moon of the Empire, would spend each summer in the lands of the Great Northern Empire. There, under the gentle warmth of the summer sun, he would come to know Tsesarevich Viktor, the future Tsar, in a world where the chill of winter softened into something more welcoming.

This arrangement would begin when Yuuri reached the age of seven—a time when he would be old enough to travel. With each passing summer, the two princes will discover whether their connection was destined to remain one of friendship, or if it might blossom into something more, something that could unite their kingdoms as well as their hearts.

For love, as the three rulers knew, was the most powerful bond of all—a force that could bridge even the greatest distances and bring together hearts and souls.

 


 

After a month and a half, it was time to return home and the road was long in between seas.

As they prepared to leave, Elena looked back at the palace one last time. The sun dipped low in the sky, casting a golden hue over the palace gardens, Viktor turned to his mother, his eyes wide with a question that had been forming in his mind.

“Mama, can we take him home with us?” Viktor asked, his voice earnest and a deep pout in his lips. His heart is full of the simple, innocent wish to keep this newfound friend close.

Elena laughed softly, shaking her head as she knelt beside her son.

“Do not worry, my love. This is not goodbye. You will see him again. Every summer, you will spend time together, in our home. And one day, when you’re both older, perhaps…” She trailed off, leaving the rest unsaid. “Come, Vitya. We have much to do when we return home.” Elena took her son’s hand, and together they stepped into the carriage that would take them back to the cold, unforgiving north.

But as the carriage wheels began to turn, Viktor looked back at the palace.

In the distance, he could see the Empress Consort standing by the gates, cradling baby Prince Yuuri in her arms.

 





As Viktor grew, his carefree days became more structured. By eight, his schedule was packed with lessons in statecraft, military strategy, and diplomacy. There was also fencing, advanced horsing lessons and skating - this last one becoming his favorite activity. The Tsesarevich also became more aware of his surroundings though he was praised for his quick mind and charm, it was difficult not to notice the way the court watched him, whispering about his potential and the great legacy he was expected to carry. At eleven, his silvery hair now long and his face sharpening into the features of a young prince, Viktor started to craft the image of the perfect heir—aloof, charming, and flawlessly composed. 

He had stopped calling his mother “Mama” opting for the more formal “Mother” a sign of the end of his childhood. His closest companions were his cousins—Georgi, who loved tragic poetry; Mila, always energetic and open-minded; they had just had a little baby brother and used every excuse to babble to Viktor about little Yuri.

Even so, Viktor kept a certain distance, knowing that as the future Tsar, perfection was not just expected but required.

“You are the future of this empire, Viktor,” His uncle Yakov would often remind him, his tone stern. “You cannot afford to be anything less than perfect.”

Viktor would nod seriously, though inside, he was often rolling his eyes. 

Perfection, he had learned, was a game—a game he was becoming very skilled at playing.

 


 

When Tsesarevich Viktor approached his twelfth birthday, he was well aware of the expectations placed upon him.

He was to rule, after all, and with that title came certain responsibilities—responsibilities that often left him feeling like he was wearing a very heavy crown, even if it wasn’t on his head yet. But Viktor had become quite good at pretending. He had perfected the art of the charming smile, the graceful bow, and the casual wave that made everyone around him feel at ease. But there were times when all he wanted was to escape to the ice rink and forget about being the perfect prince, even if just for a little while.

It was during one of these skating sessions, lost in the perfection of a particularly challenging jump, that Viktor was interrupted by a palace servant. He landed smoothly, though with a hint of annoyance that he quickly masked with a polite smile.

“Yes? What is it?” He asked, his tone smooth but tinged with the dramatic annoyance only an eleven-year-old could muster.

“Your mother wishes to speak with you, Your Highness.” the servant replied, bowing slightly.

Viktor sighed, pushing a strand of his long silver hair behind his ear. 

“Very well.” he said, though the thought of cutting his practice short didn’t sit well with him. 

He followed the servant back to the palace, where his mother was waiting in her chambers, gazing out over the snow-covered gardens.

“Mother,” Viktor greeted her as he entered the room. “You wanted to see me?”

Elena turned to him, her expression warm but tinged with amusement. “Yes, Vitya. There’s something we need to discuss. It’s about the upcoming summer.”

Viktor tilted his head slightly, with caution. Summer was his time—a break, the season where the court’s pressures eased and his lessons were also cut short compared to the rest of the year. Three months almost free of the pressures of everything on his shoulders, to focus on his skating and maybe even indulge in some of the novels he secretly enjoyed.

“What about it?” He asked, a touch of suspicion in his voice.

Elena smiled, clearly sensing his hesitation.

“Do you remember Prince Yuuri, from the East Sun Empire?” She asked.

Viktor blinked, trying to recall the vague memory of a baby with dark eyes and soft black hair. It was a long time ago, and the memory was hazy at best. “I think so… He was just a baby back then, wasn’t he?”

Elena nodded. “Yes, that’s right. But Prince Yuuri has grown since then, and this summer, he’ll be visiting our empire.”

“Visiting us? Here? For the whole summer?” Viktor’s eyes widened slightly in surprise. 

“Yes.” Elena confirmed. “It’s part of an arrangement we made years ago to strengthen the bond between our empires.”

Viktor’s frown deepened. An arrangement? He’d heard that word often in his studies—arrangements, alliances, unions. All of them were strategic moves on a chessboard where people were the pieces. He’d read about them in the histories, learned about them from his tutors. But this was different. This wasn’t some abstract concept or a story from the past—this was about him.

“And what am I supposed to do with him? Read him stories before bed?” Viktor frowned, irritation bubbling up inside him. The idea of being a babysitter for an entire summer was infuriating.

Elena chuckled softly. 

“Vitya don’t be silly, he’s only four years younger than you. I’m sure you’ll find something to do together. Besides, it’s important that you spend time with him, get to know one another. After all, there’s a possibility that—”

“Oh no…” Viktor interrupted, holding up a hand dramatically. “Let me guess. We’re supposed to be best friends, or something, and then get married and unite the empires, right?”

Elena smiled, not entirely denying his playful accusation. “Perhaps. But no one is forcing you into anything. This is just a chance for you to meet and see if, well...”

He’d read about strategic marriages in his studies, how kings and queens were often paired off to secure alliances. But he was eleven! The very idea of being married off to some prince he didn’t even know made his skin crawl. He’d barely started to figure out who he was, let alone who he wanted to spend the rest of his life with.

Viktor let out a long, theatrical sigh, flopping into a nearby chair with a grace that only a young prince could manage. 

“Mother, I don’t have time to babysit some kid who probably still sucks his thumb.” Viktor grumbled, side-eyeing her with disbelief. The idea of spending his summer with someone who might be his future… whatever, was annoying at best.

Elena raised an eyebrow, her smile widening. “Not so long ago you were seven once, too. And I’m sure Prince Yuuri doesn’t suck his thumb anymore.”

“Are you sure about that?” Viktor muttered under his breath, but loud enough for his mother to hear. He sighed again, this time more out of resignation than anything else. “Alright, fine. I’ll be the perfect host. But I’m not making any promises about liking him.”

Elena reached out to ruffle his hair, but Viktor dodged playfully, smoothing his long locks back into place with exaggerated care. No one touches the hair, he thought with a flicker of amusement, though he allowed himself a small, teasing smile.

“I’m getting too old for that, Mother,” he teased, though there was a twinkle in his eye that showed he didn’t really mind the attention. As much as he wanted to be annoyed, there was a part of him that enjoyed the banter with his mother.

“Thank you, Vitya.” Elena said, her voice softening. “Just give him a chance. You might be surprised.”

Surprised? He’d met plenty of foreign dignitaries, children of nobility, and other princes and princesses. Most of them were dull, their lives dictated by the same expectations that now ruled his own. But he knew better than to argue. “We’ll see,” he said, standing up and heading for the door. “Now, if you’ll excuse me, I have some skating to do before I’m forced to play tour guide.”

Elena watched him go, shaking her head with a smile. Viktor was growing up, but she just hoped that this summer would bring him something more—something that might help him see beyond the walls he had started to build around himself.
