Many months had passed, and Xavier had turned eight years old, having lived with Alcmena for a year and receiving much training from him.

Throughout the months, Xavier and Alcmena developed a strong bond as master and student. Alcmena assisted Xavier in better understanding the Runes of Eldora, as well as achieving and mastering his newly acquired green Expert Core.

Now in the deep woods, Alcmena was teaching Xavier how to use RealmHeart.

However, Xavier struggled to use it, as golden markings and Eldora rune symbols appeared on his right hand, gradually progressing to the right side of his face. With his hair lighting up with a faint yellow.

"Concentrate, Xavier," Alcmena murmured, as Xavier yelled in agony while attempting to maintain RealmHeart.

However, Xavier eventually gave up and collapsed to the ground, exhausted.

"I can't; it's too difficult to use," Xavier said to Alcmena, breathing heavily.

"Let alone maintain it for a few seconds," he added.

King Alcmena sighed and replied, "You still don't understand what RealmHeart is, am I wrong?"

And Xavier responded, "I didn't even understand it when you first told me what it was."

King Alcmena chuckled and added, "Well, allow me to give you the pleasure of hearing it again.".

"Listen closely this time," he said.

Coughing to clear his throat, King Alcmena began explaining what RealmHeart was to Xavier again.

"To begin, as I explained to you before,".

"I had implanted the Dragon Seed into your very essence.".

"Which not only indicated that you have a bond with a dragon, but that you could access my powers.".

"So every time you try to access my powers, the Dragon Seed creates a reaction chain in which an abundance of power flows through your very being.".

"And that energy or effect is what is known as Realmheart".

King Alcmena went on to explain that "there are many stages to Realmheart.".

"And for each stage, your appearance begins to change to that of a dragon as you get closer to using my full powers.".

"But for now, we'll stick to you being able to use and master Stage One of Realmheart.".

"So you can be able to use my powers; otherwise, you won't even be able to use a single one of my abilities if you don't learn and activate Realmheart.".

Xavier followed with a question: "So those rune markings that began to form on the right side of my body were me tapping into RealmHeart?"

King Alcmena answered his question by explaining that the rune markings and the color change in his hair indicated that he was using his draconic powers.

"That's awesome!" exclaimed Xavier joyfully.

"I can't wait to master RealmHeart, so I can learn how to use your powers," he continued.

King Alcmena laughed as he saw Xavier's delight and said menacingly, "Now get ready, Xavier.".

"Because we're not done with our training.".

Xavier was surprised and said, "What?"

"What's our next session?".

To which King Alcmena answered, "Our next session will teach you how to use your powers perfectly during heated battles."

"Which should also aid you in accessing RealmHeart quicker.".

"So, who am I fighting with this time?" Xavier inquired.

King Alcmena responded with a threatening sneer, "You will be fighting me this time.".

Xavier smirked and replied, "Well, I'm glad I get to have a challenge this time.".

King Alcmena burst out laughing in response, and with the snap of a finger, he summoned a swarm of humanoid werewolves armed with armor and weapons.

Warming himself up, Xavier put out his hand, and in an instant, Excalibur, which was lying back in the room altar in King Alcmena's home, flew into Xavier's grasp.

"Be sure you don't die, Xavier," King Alcmena joked.

To which Xavier responded, "I do not intend to die or lose this fight."

All of the werewolves charged at Xavier at once, but their strikes were quickly stopped by Xavier's vector shield. And all of their attacks reflected on them with double the force, gravely wounding them.

With Excalibur in his right hand, Xavier killed one of the werewolves before kicking another away.

The werewolves continued to attack Xavier, but he easily teleported away before their attacks could land.

Xavier tripped one of them to the ground, placed his foot on their heads, and killed them with his vector air bullets.

Xavier grasped Excalibur with both hands and slaughtered all of the werewolves in a single swing. Which mistakenly severed one of the moons surrounding the planet where they dwelt.

"That easily?" Xavier asked himself in amazement.

"I didn't even use my Regokinesis Blade Technique.".

"And it easily cut through the werewolves and the moon, like butter.".

"What kind of sword is this?" he asked excitedly.

Seeing Xavier let his guard down, King Alcmena struck him with his tail. However, Xavier was able to deflect the strike in time, as his vector shield automatically activated to protect him from harm.

To Xavier's disbelief, King Alcmena was able to exploit his vector shield's automatic mechanism by reversing his strike at the precise time of contact with the field's area of effect, causing it to attract the attack toward Xavier. Allowing King Alcmena to use his tail to damage Xavier, which was so powerful that it launched Xavier into orbit.

Crashing into another one of the moons orbiting the planet they inhabited at tremendous speeds, making a large crater on it, Xavier slowly stood up in agony.

And he wondered to himself, "How was he able to hit me?"

"Did he do the same thing big brother Aleksander did when we used to train together to master my vector powers?".

"I thought only Big Brother could do it since he had it; it was quite weird and odd to do.".

But then Xavier's body began to freeze as he suffocated due to a lack of oxygen.

Xavier attempted to control the vectors of individual oxygen molecules, directing them into his lungs while simultaneously expelling carbon dioxide molecules from his body. But it took too much time and concentration to complete.

So he chose a new approach, using his vector manipulation abilities to temporarily suppress his physiological requirements, particularly his need for oxygen.

He began enhancing the efficiency of oxygen consumption within his body by regulating the vectors involved in cellular respiration to recycle oxygen more effectively, ensuring that every molecule of oxygen is utilized to its full potential. Increasing the time he can endure in an oxygen-deprived atmosphere.

As Xavier prepared to return to the planet, King Alcmena unleashed Dragon Fear, a thunderous and terrifying roar that shook the entire realm they were in. It filled Xavier's mind and body with chaos and the fear of death as he collapsed to the ground, unable to stand up.

King Alcmena deactivated Dragon Fear and began to gather up an enormous quantity of energy within his heavenly dragon horns. Xavier saw this with his cosmic eyes and began channeling a surplus of vectors into Excalibur as he prepared to use Vector Nova to repel King Alcmena's attack.

And in an instant, King Alcmena unleashed his Cosmic Canon attack, which fired out of his dragon horns and into space in the direction of Xavier.

Xavier instantly released Vector Nova, which clashed with King Alcmena's Cosmic Canon. Creating a colossal explosion, utterly dwarfing the entire globe.

As the explosion subsided, King Alcmena gazed into the skies, wondering if Xavier was okay.

"Surely he didn't die from that," he reasoned to himself.

"I made sure to withdraw its firepower, so he wouldn't die.".

At that moment, Xavier fell back to the ground from orbit, having his entire body almost completely charred.

"Are you alright, kid?" King Alcmena said, looking down at Xavier.

"Yeah... "Just a little burned," Xavier replied in discomfort and pain.

King Alcmena laughed in response and bent his head, bonding heads with Xavier. At that point, the Dragon Seed within Xavier began to react, and his body began gradually healing from the horrific burns.

As Xavier's body healed entirely, King Alcmena took him and placed him on his back.

Telling Xavier joyfully, "Alright now, that's enough training for today.".

"Let's go have something to eat.".

Xavier joyfully said, "Yey!!"

"I hope we're having your delicious meat stew today.".

King Alcmena grinned and remarked, "You love my meat stew a lot, huh?."

Xavier responded, "Of course, I do!"

"They're very yummy!".

Hearing Xavier's comment, King Alcmena was happy to hear someone praise his cooking talents for the first time in a long time, as his mother, Sylvia, was the only one who would do so. But has been dead for many years.

It was the next day, and Xavier and King Alcmena were having an emotional exchange. After a year of staying with King Alcmena, Xavier had to return to his planet and his friends. Because they might be missing him now.

Gripping Excalibur tightly, which was wrapped around his golden-red scarf, Xavier asked King Alcmena with a mournful look, "Do I have to leave?"

"Can't I stay for another year or two?" he continued.

To which King Alcmena said, "Oh, come on, Xavier."

"You know you have to return to your family.".

"They miss you so much," he added.

Xavier lowered his head in disappointment and asked King Alcmena why he didn't want to follow him back to the human world.

And King Alcmena replied, explaining to Xavier that he couldn't go since dragons weren't allowed in the human world. And if he came with him, he and his family would face numerous difficulties.

Plus, he was too attached to the realm he had created, which had become his new home, much like the dragon realm. And he couldn't bring himself to leave all the memories he'd made there behind.

Xavier expressed his regret and disappointment, but King Alcmena comforted him, asking him not to be sad. However, Xavier couldn't stop himself from crying.

Seeing Xavier's tears, King Alcmena took a deep breath and sighed. Taking time to consider what he could do to make Xavier happy again.

After a brief reflection, King Alcmena informed Xavier that he had a gift for him before he returned home.

Xavier wondered what the present could be, then King Alcmena bit his finger and lowered it to the ground, dripping blood on the ground.

But then King Alcmena's blood began to mix with the ground, forming a little creature from it. King Alcmena then constructed an eggshell and placed the creature inside.

Giving it to Xavier and adding, "This is the gift I have for you.".

"What is it?" Xavier questioned, perplexed.

King Alcmena explained to Xavier that he had created a baby replica of himself with all of his memories and abilities.

Xavier was both astonished and delighted that he would be able to continue being with King Alcmena, albeit in a new way.

King Alcmena was pleased when he saw Xavier's smile return and informed him that the infant version of himself he had created had half of his consciousness, but not all. On the other bright side, it will increase in power with him, training and assisting his development as a vessel and using his new powers as the vessel of the Dragon King.

All Xavier had to do was foster and take care of the dragon egg until his other version hatched from its shell.

King Alcmena told Xavier that he needed to keep his other version a secret since what he had just done was entirely forbidden and may land him in trouble with the four races.

Xavier nodded in agreement, promising King Alcmena that he would keep both their covenant and the dragon a secret.

King Alcmena smiled in response, but Xavier embraced him zealously. Which startled Alcmena and caused him to experience a feeling he had never felt in his millions of lives as a dragon.

"I love you, Master Alcmena," Xavier remarked, smiling brightly.

King Alcmena stood there in disbelief, unsure what to do because this was the first time he had been treated this way.

He then softly caressed Xavier's head and smiled lovingly at him.

King Alcmena created a gateway that served as an exit and would transport Xavier back to the human realm.

As Xavier approached the portal, holding Excalibur and the dragon egg, King Alcmena watched him walk away. And he couldn't bring himself to speak the words "I love you too" to Xavier because he didn't think he was worthy of doing so.

When Xavier arrived at the portal King Alcmena had created, he waved goodbye to him, who returned the gesture as he passed through it.

As Xavier left, King Alcmena felt a burning sensation in his chest, as if he had lost something very essential to him.

Because he no longer saw Xavier as a vessel or a student, but as a son whom he raised for a long time.

A son he watched over and helped grow as a person. A son he loved unconditionally and more than himself.

And that son was now leaving him to continue his journey across the big and beautiful world that awaited him.

With a pleased smile on his face, King Alcmena bid Xavier farewell, reflecting on their time together as master student and father-son.

As Xavier passed through the portal, a blinding light blinded him, and he couldn't see anything because of how bright it was.

While traveling across numerous realms and universes, Xavier heard a voice calling continuously.

Xavier gently opened his eyes, and when he did so, he suddenly saw he was resting in a hospital bed.

With his vision still fuzzy, Xavier observed an extremely attractive man sitting in the corner on one of the chairs in his hospital room.

"Papa?" Xavier asked, looking at the attractive man in amazement because they appeared to be identical to Jonathan at first. But he had black eyes, unlike Jonathan's, who had dark crimson ones.

"I'm not Jonathan, Xavier," the man responded, laughing.

"It's me, your uncle, Percival," he added.

"Percival?" Xavier asked, not knowing who the man was.

At that point, Jonathan walked into Xavier's room and was astonished to find Percival.

"Brother?" Jonathan asked, shocked.
