Mystic Bone Art allowed Mammoth Clansmen to transform into Pranic Beast that they had fused with at the Body Stage. This was their genetic capability. Even children had this capability. They only had to enter the Body Stage to gain access to the power.
When a Mammoth Clansman transforms into a Pranic Beast, their actual bodies will be housed in a space formed within their Spirit Containers, similar to a biome. Though connected, both their Mammoth Clansman bodies and Pranic Beast bodies were different.
The principle of conservation of mass applied to even Sumatra. When Mammoth Clansmen transformed, they were employing the power of an Empyrean Tusk's biome, which was an effect derived from Internal Inertial Gravity.
And when Brangara consumed Mammoth Clan children through Voracious Nature, he accumulated their genetic characteristics. Eventually, while surviving on a strict diet of Mammoth Clan children flesh, and upon being able to use Mystic Bone Art, Brangara obtained the same characteristics.
Him adapting to this extreme situation derived the power of an Empyrean Tusk, associated with the creation of biomes, similar to the Mammoth Clansmen in his body. It ended up manifesting as the Tertiary Nature of Cultivator.
That's why in Brangara's case, he could assume two different forms—human and Pranic Beast. His Spirit Container had developed a biome within it that housed one of his bodies in either form.
In the case of the Mammoth Clansmen, this was a characteristic. That's why every time they transformed, Prana was expended accordingly, because their Spirit Containers were shrinking or expanding the space within it accordingly to spit out the body or retract it.
But in Brangara's case, the characteristic had become a Nature, resulting in a biome that was maintained at its largest size, with a large enough door to pull in and out his Pranic Beast form. It was why he didn't have any Prana expenditure for transformation, since the space in his Spirit Container didn't have to change.
Brangara ended up deriving the power of Internal Inertial Gravity to another extreme, resulting in the Nature of Cultivator. This was the actual culprit that turned him insane.
Similar to the Nature of Weaponisation, Cultivator too was a Nature closely in harmony with an Empyrean Tusk. This made Brangara susceptible to the influence of an Empyrean Tusk, similar to how the Mammoth Clan Virala was susceptible to Gannala's influence.
It was why the greater the number of Natures of Internal Inertial Gravity in his Astral Chart, the stronger Brangara had been influenced. His Tertiary Nature of Cultivator created a large doorway that conducted the influence of Internal Inertial Gravity into his being.
This was what resulted in his state of being more Empyrean Tusk than an Empyrean Tusk towards the end of Sumatra Chronicles. It was why no matter how much he wanted to stay sane, Brangara became maddened with rage the moment he spotted an Empyrean Tusk.
But now, Cultivator had been morphed into Voracious Cultivator. That was why the Celestial Boar had a better grasp of his emotions. Only Gannala was able to harness a strong reaction out of him, and even that had its limitations, as she observed at the Zahara Kingdom.
When his family was threatened, he was able to swallow his hatred for Gannala and send a body to assist his family. Had his Nature not been Voracious Cultivator but simply Cultivator, he would have been relentlessly chasing after Gannala with both his bodies.
When she faced him directly, it was when everything clicked for Gannala, allowing her to understand the process through which Brangara derived the Nature of Cultivator and how she could do the same through Internal Inertial Gravity.
This was when her overview of Inala changed, able to observe him with greater awe. The Nature of Cultivator she possessed might seem similar to Brangara's, but in essence, it was completely different.
Her Cultivator was derived from Cooter Clansmen. This was an effect that could be reached when Subtle Terrain Domination was taken to the extreme. It was why when she entered the Nature slot of someone and unleashed the influence of her Nature of Cultivator, they gained a human form.
Subtle Terrain Domination was creating a space in which this body was stored. The end result of both Natures of Cultivator was the same but the process they achieved it couldn't be similar.
Gannala hadn't researched Maroppa's Nature of Cultivator, for she hadn't had the time to do so, and since she already achieved what she wanted by understanding the mechanism behind her and Brangara's Nature of Cultivator.
The power she wanted to gain was the principle behind the creation of Weaponisation and Cultivator. It took advantage of Mystic Bone Art and Internal Inertial Gravity in a certain way, which had significant potential.
She equipped herself onto the Nature slot of an Empyrean Zinger—with the Secondary Nature of Subtle Terrain Domination. This allowed her to better control Virala's body, able to pause the process wherever she pleased.
Only Virala, with the Mystic Grade Nature of Weaponisation, was perfectly susceptible to her influence. Anyone else, even with a Gold Grade Nature of Weaponisation wouldn't be under her perfect control, causing missteps during the process.
Even missing a single beat would result in an implosion. If she didn't have the Mammoth Clansman Virala in her possession, Gannala wouldn't have dared attempt this.
It took her a couple of days, at the end of which she stared at the Nature Weapon in her hand that now had a Mystic Grade Nature of Internal Inertial Gravity. Honestly, as long as she fuses this with a talented Mammoth Clansman, they'd become a powerhouse.
But that wasn't enough, as her goals spanned beyond. Now that she had obtained the Mystic Grade Nature of Internal Inertial Gravity, Gannala began to derive it once again, arriving at the Mystic Grade Nature of Weaponisation, taking a bit less than two days this time.
She repeated the process, constantly changing Virala's Nature Weapon form, using her influence to alter his mind accordingly. And whenever necessary, she used Dance of Recovery to revert him to human form.
Immediately after, she used Dance of Annihilation to turn him into Nature Weapon form, looping the process. She kept it up for days, smiling upon seeing that Virala's condition was no different from living in an extreme state.
She maintained the process for over a year, constantly telling the nervous Mammoth Clan to stay put until she was done. Since they had transferred the Mammoth Treasury to her, they couldn't tell her otherwise.
She could do whatever she wanted with the Mammoth Treasury, since that became her responsibility. And under her constant urge, they continued to remain in their hiding spot, completing their preparations to travel through the Sandy-Grey Void.
They were constructing a giant ship, with the materials sourced solely from the tusks of the Empyrean Tusks. Maroppa was infusing her power into it, stabilising the structure through three pieces of Sumatra Gold that Orakha had lying extra.
They'll seamlessly integrate the ship with Maroppa's Spirit Weapons, ensuring it can withstand the Sandy-Grey Void without issues. As it was a complicated construction, it was taking time, even with the combined efforts of all Empyrean Tusks, Raaha, Maroppa, and Orakha.
As a result, they could wait until Gannala did her thing. And a year after remaining in the extreme state, a change erupted in the Nature Weapon form of Virala.
Secondary Nature—Internal Derivative Refiner!
The Mammoth Clansman Virala only had a Secondary Nature, with his Primary and Tertiary Nature slots being empty. And now, through keeping him in an extreme state where his Nature continued to alternate between Internal Inertial Gravity, Weaponisation, and Cultivator, he gradually adapted, resulting in a brand-new Nature, one with change as its power.
Internal Derivative Refiner was capable of deriving Natures from an Empyrean Tusk's existence. That was its power. As a Mystic Grade Nature, its power was on a whole other level. As all Mammoth Clansmen had Empyrean Tusk genes, depending on the quality and concentration of their genes, Internal Derivative Refiner could condense a Nature related to the characteristics of an Empyrean Tusk in them.
However, the Mammoth Clansman must possess the Nature of Internal Derivative Refiner first. And, this Nature was a one-
time use, similar to the Nature of Phells—Needle Mine!
Once used, it would derive the characteristics into a Nature and vanish. The user would also need to have the necessary knowledge, otherwise it wouldn't condense any Nature and simply be expended needlessly.
It was a major waste of a Mystic Grade Nature, having it be a single-use Nature. However, Gannala planned to make it a part of the Major Treasure of Arsenal, able to use it without issues.
Now that she had successfully created her intended Nature, she focused on the Major Treasure of Arsenal, activating Subtle Terrain Domination. Gradually, she seeped her influence into the Major Treasure, taking over eight months to do so.
Following that, she identified the Nature of Thought Condensation that had been fused into the Major Treasure of Arsenal, using Subtle Terrain Domination to erase it bit by bit, taking ample care to avoid damaging the Major Treasure.
Boom!
The Mammoth Treasury rumbled as the influence—from the Major Treasure of Arsenal—in it began to flow out. Gradually, it formed a wave and entered the Major Treasure of Arsenal, called back to recover from the damage it was sustaining.
'I need to finish it soon.' Sweat covered her forehead as Gannala intensified her focus. The damage she does to the Major Treasure could heal as it absorbs its influence from the Mammoth Treasury.
But the moment it absorbs all of the influence it had generated upon the Mammoth Treasury over twelve millennia, it would be unable to recover any longer. So, she had to complete her process before that happened. Otherwise, the Major Treasure of Refiner would be permanently damaged.
'Faster! Faster!' She thought and harnessed copious amounts of Prana from her biomes to use Subtle Terrain Domination with, keeping a mental note of her pending work and the amount of the Major Treasure's influence left in the Mammoth Treasury.
"Is this…for the better or worse?" Raaha stared at the figure of the crumbling Mammoth Treasury, sighing as he didn't know anymore. He never felt so lacking in confidence as the Mammoth Clan Chief.
Originally, he was confident, because from the moment he took position as the Mammoth Clan Chief, not a single Empyrean Tusk had been killed by the Boar King. However, after the merger, too many variables occurred.
Even though he tried his best to keep everything in check, things spiralled out of his control. The strength of the variables and Brangara had been growing at an exponential pace while he remained stagnant.
And the moment he announced the decision to flee Sumatra Continent, he lost all confidence in himself. That was why he wasn't in the least opposed to the idea of transferring his power of the Gold Empyrean Tentacle. He felt he was no longer suited to the task.
'I don't know anymore. Whatever ought to happen will happen.' In resignation, he sat cross-legged on the floor and observed the Mammoth Treasury continue to crumble. Multiple streaks of light burst out through the rubble, entering the bodies of the Empyrean Tusks according to their affinity.
Gannala had already decided upon the Empyrean Tusks that would fuse with the Minor Treasures in the Mammoth Treasury. The Empyrean Tusks stared at the crumbling Mammoth Treasury with a complicated gaze, feeling lacking to wield the power of a Minor Treasure each.
Finally, two years since she had entered the Mammoth Treasury, Gannala walked out, amidst the rubble of a now collapsed Mammoth Treasury. Her weak steps displayed her exhaustion, but her face expressed abundant elation.
She slowly walked towards Vhalla and grabbed her arm, "Please follow the knowledge I'm streaming into you."
"Alright," Vhalla didn't resist and absorbed the information being inscribed on her skeleton by Gannala. Her eyes lit up in shock as a voracious stream of power spiked out of Gannala and seeped into her, occupying her Tertiary Nature slot.
"Now, follow the instructions." Gannala said, her voice weary, but her eyes glinting with maniacal radiance, 'I guess genetics never lies. I'm most exhilarated when creating new concepts, just like Inala.'
As Vhalla followed the instructions in her Bone Slip and activated the Nature of Internal Derivative Refiner in her Tertiary Nature slot, her Primary Nature of Internal Inertial Gravity whirred into life, drawing up copious amounts of her Prana.
It gradually concentrated into her Tertiary Nature slot, taking position as the effect of Internal Derivative Refiner was fully consumed.
Tertiary Nature—Cultivator!
"T-This is?" Vhalla stared in absolute shock, unable to understand how in a mere few minutes, she managed to condense a Nature, that too of Cultivator. Instinctively, she realised that she could now cultivate through the Life Stage, able to freely switch between human and Pranic Beast forms even without Gannala's assistant.
Vhalla stood still like a statue, still processing what had happened. But in the meantime, Gannala approached the 2nd Empyrean Tusk, Rhanalla, and grabbed her hands, "Follow my instructions."
A few minutes later, Rhanalla was still as a statue, just like Vhalla. But ignoring the duo, Gannala approached the 3rd Empyrean Tusk and grabbed her hand, "Follow my instructions."
"Follow my instructions."
