Adventure Time : A True Journey

**POV: Finn the Human**

Finn understood that focus and control were among the two most important qualities he needed to achieve in every practice session.

To remain both focused and in control was his goal.

Within the environment of the Nomicon, where he could adjust everything to his liking, it was not too difficult for Finn to attain such a state of focus.

Once again, Finn was practicing his use of the Teingu flame. However, this time, instead of swirling the flames around him in different patterns or at various speeds, he aimed to control the shape of the flame.

He shifted the flames from a cube to a sphere, then to a flat surface, and even created more complex objects like a sword and an open book with pages that began to turn. 

Control was his priority now.

"Concentrate, Finn. You're paying too much attention to the flame's control instead of forming your mind palace," the red Shogun remarked, becoming a symbol of wise counsel—a sort of ancient master.

Finn furrowed his brows, acknowledging that the Shogun's words were true.

Yes, while he was practicing focus and control, he was also developing his ability to multitask, or as some might call it, parallel thinking.

At that moment, while he was putting the finishing touches on his mind palace, the intricate process he had started earlier continued, even as his mind engaged in another task. This level of control demonstrated his exceptional skill.

He was becoming a true genius of progress and adaptability.

Finn viewed both processes as personal challenges, and he was handling them exceptionally well.

Even the shogun's suggestion that he should focus more on his flame control was merely a tactic to distract him. It didn't succeed.

Finn was aware of this; he was the one managing multiple tasks simultaneously.

Forming a mind palace was not as difficult as one might think, especially for the current Finn.

Leo was a genius who had created something akin to a mind palace and possessed a sort of perfect memory. The original Finn was even more intriguing than the current Finn had come to understand.

Unbeknownst to him, the original Finn had somehow established a mind vault to suppress his traumatic memories or any memories he preferred not to remember. More specifically, the vault was suppressing the essence of Finn's past reincarnations. A truly remarkable thing.

This was an intriguing discovery. While it made the formation of the mind palace slightly more challenging, it didn't pose a significant problem. For now, Finn chose not to delve into that essence, which he believed to be the memories of his previous self. His instincts told him it was simply not the right time.

Finn largely understood what the vault contained and had thus far avoided opening it. He was uncertain how long it might take to explore the memories of his past life, and he preferred to postpone that journey for now.

Finn was already struggling to organize both Leo's memories and those of the young Finn, which was a considerable task.

With the two-character templates, Finn managed to build a solid mind palace—something he felt satisfied with, at least.

Finn employed a trap concept when creating his mind palace. It began with a tall tower set in a beautiful garden filled with various trees and flowers. 

This served as the initial defense for any invaders, absorbing the brunt of all attacks while simultaneously acting as the first trap.

The garden operated on a simple principle: enchanting, reflection, and replication. Its main objective was to study anyone who stepped inside, instantly copying and saving everything about them. And its other minor function was to enchant anyone who was weak-willed enough who would then be handled by either Finn himself or the residents of the tower.

Moving into the tower, Finn applied the concept of infinity. This meant that once someone began to climb the tower, they would find themselves in an endless ascent. That's when the garden's second trap would activate.

Climbers would be forced to confront different versions of themselves, either until one of those versions killed them or they were driven insane by the act of destroying their reflections. In either case, the cycle would not end—the term "infinite" was deliberate.

However, the tower was ultimately an illusion.

One might assume that ascending the tower would grant them access to his memories, but the tower was a ruse designed to exhaust any intruder, preventing them from quickly accessing anything in his mind.

His memories were stored in a much more conspicuous location. The garden and tower were nestled within a dark panorama crowned by a sky full of countless stars—a true nebula.

 Within one of those stars, Finn had constructed a supercomputer powered by the star it resided within. 

Finn was surprised when the creation of the computer itself boosted his mental capabilities. His comprehension, reaction speed, memory, and even his imagination had been boosted! The computer acted as a wonderful channel to organize all his memories in file compartments and countless encryptions.

Anyone who managed to see through all these defenses would face his final two traps.

First, upon reaching the supercomputer housing his memories, every file would morph into a virus and launch a counterattack against the intruder's mind. A sort of last-ditch effort to kill the intruder, while a backup file would start to be created in another one of the far-off stars.

 During this assault, the nearby stars would bombard the intruder as well, creating a scenario of true overkill.

Finn initially thought that his approach might be excessive, but when he considered that anything that could infiltrate his mind was potentially cosmic level in nature—and with the Nomicon's assurance that it would be backing him up through the whole process, he went all out—he understood the need for it. 

He even had a file on his computer labeled "vault memories," containing what he believed to be the essence of every one of his past selves. Each entry contained the memories of his previous incarnations, and Finn preferred not to confront that reality now. 

His instincts told him that now was not the time.

Finn was confident that even Goliad, one of the only telepaths he knew about from the show, would be unable to bypass this mental shield. Yet, Finn knew that his ego was speaking; reality could turn out to be different.

The process of organizing the two personalities had its challenges, despite Finn's efforts to make it seem effortless. 

For example, he had to sift through every single memory of both individuals, deciding which to merge and which to keep separate. 

Moreover, Leo needed to organize and keep track of specific memories of importance, and at times he found himself embarrassed by certain recollections.

Nevertheless, Finn believed that the path he had chosen allowed him to see this new self of his in a different light.

The entire process was eye-opening. It felt like seeing himself for the first time as he sorted through the memories of both individuals. 

It was as if this process was transforming him into a new person, embodying both Finn and Leo as he relived their memories.

Each organized memory felt like navigating a richly detailed virtual simulator in which he was both a spectator and a protagonist, journeying from childhood to the present.

 He experienced a range of emotions—joyful memories, strange ones, and everything in between. Each recollection was vivid, filled with emotion and purpose.

It was an incredible feeling.

Surprisingly, Finn felt a sense of freedom with each new emotion that emerged from the memories of both sides. At that moment, his memories felt entirely his—neither solely Finn nor Leo, just him.

This realization brought a kind of freedom that Finn had never known, making him feel lighter and less constrained in his heart.

It was an unusual sensation.

As his mental space took shape, Finn admired the beauty of his mind and felt an odd sense of liberation.

Perhaps it was due to the absence of a physical body, or perhaps the beauty he had created had calmed him, but at that moment, Finn felt he had completely accepted himself.

He embraced everything about his present and past selves, and he found solace in that acceptance.

Finn could confidently say that he had, in a way, come to understand the essence of his being through the formation of his mental tower. This understanding brought surprising benefits.

His mental eyes opened wide, and everything appeared renewed. Even the red Shogun waiting before him looked different.

"How strange," Finn thought. Why did the Shogun suddenly appear blurry?

"You have done it, Finn. You have achieved a state of enlightenment that I anticipated you would reach even sooner than expected," the Shogun said, its once-deep voice sounding oddly altered.

But the Shogun's words quickly piqued his curiosity. Was this its original intention when it guided him to create a mind palace? Was this newfound fulfillment truly its purpose?

"As you may have realized, the formation of the mind palace served many purposes—some to protect your mind, and others that were more beneficial..."

Finn was now certain that the Shogun's voice had changed. But why?

"It was designed to fully integrate the essence of The Young Finn and Leo."

Finn was taken aback by this revelation but not overly surprised; he had lived through the entire experience and could feel the changes within himself. However, what did it mean to join the essence of the two? In his current state, the answer seemed less important.

Yet, there was something Finn was eager to know.

"Nomicon, show me how I look," Finn commanded. For the first time since entering the Nomicon, he wanted to see his appearance, to understand how he perceived his newly unified self.

The Nomicon snapped its fingers, and a full-length mirror materialized. Finn gazed into the reflection, and a bright smile spread across his face, one that the image mirrored back at him.

"I think I understand a little about how my soul looks," Finn said, his smile remaining.

...….Adventure Time...

A/N

In the end, Finn's understanding of how his soul appeared symbolized his acceptance of who he was, suggesting a deeper comprehension of his essence and memories.

For a deeper explanation, imagine that originally, the two souls, memories, or whatever were one, but there existed tiny almost invisible cracks that still made them separate despite being one. Now forming the mind palace made these cracks disappear and now there is a fully formed soul, both Leo and Finn and every one of his past reincarnations.

I'm also thinking of his new name being something like Finn Campbell Stormborn Mertens or something like that. Seems a proper way to pay homage.

I also want to make something clear. The current protagonist is still a child so most of the time he'll either be silent or acting as a child. He is also supper smart, adventurous and a little crazy. So in short. Finn's personality plus Leo's
