At a certain realm in Oceania where the water looked green at some times and at other times golden, forming an epic combination, a fierce battle was currently going on between 2 powerful parties.

  One of the predators was an enormous creature that looked like an elephant with a body mass eclipsing more than 5 submarines stacked together. Its tusks were long, hard, and curved like sickles of death.

  Its body was hairy but for some weird reason, scales were at some parts of its enormous body which was part of the adaptations that it had to adapt and survive in the Ocean.

  Its legs were as big as a submarine, it's head as menacing as an angry Lion. At the side of its enormous body grew out spike adaptations, these were part of the means that it attacked with its enormous body. 

  Its glowing red eyes were filled with anger, and this was reflected through its body as it attacked in a frenzied manner with everything that it had.

  This strange predatory creature was a Mammoth. 

  It was a strange already extinct land creature to be seen at sea but for some reason, this monster already adapted and was not only living in Oceania, right now it was embroiled in a super fierce battle.

  Its opponent was an even more terrifying predator than it was.

  This predator was a creature that was mostly seen in myths, this predator was a real Dragon. It's might as it dominated its opponent, and the pure primordial red fire raging around it said it all.

  This Dragon had 2 pointed horns growing from its head, its super long teeth were exposed from the sides of its death jaws, dripping brown blood savagely as it attacked its opponent.

  The claws in its arms were as sharp as razors and hard as vibranium. Grabbing and savagely ripping flesh with them dealt significant damage to the enormous Mammoth each time.

  Its wings were spread out proudly like it was the ruler of the Ocean, and spikes jutting out of joints in the wings acted as more attack options to quickly end the life of the Mammoth.

  The rough black scales flowing across its body made it look even more menacing, they seemed impenetrable. This was more visually impressive when it was paired with the fire raging around everywhere.

  At this moment, these 2 predators were embroiled in a fierce battle like there was no tomorrow. The area around them visibly shook, breaking down from the shockwaves and destruction alone.

  Each attack from them seemed capable of causing a natural disaster.

  The Mammoth was far bigger than the fire Dragon but the Dragon gave it so much trouble and pain like it was the big brother in the scene. 

  Its bite was powerful and painful for an attack, while its skin was super thick for defense which formed a deadly combination.

  Its super-hot fire did wonders, burning through the thick flesh of the Mammoth with impunity as the Mammoth reacted by propelling its thick tusk forward angrily for a collision.

  Magic power flared around the both of them, spreading natural disasters across kilometers which was a testament to the intensity of their battle.

  They both activated magic shields but none worked as the powerful attacks from either side quickly dissipated the shield's magic energy load.

  At this moment, they were both already at that point where they cared about nothing else but to spam more attacks at each other.

  With another mighty fire breath from the Dragon, the Mammoth suffered the first incapacitating injury since the battle started as the Dragon went on to take advantage of this opportunity more.

  Bites continued, claw attacks continued, all these stacked together frighteningly, increasing the injuries sustained by the Mammoth as well as already showing the potential winner of the battle.

  After receiving another vicious bite from the Dragon, the already weakened Mammoth couldn't trumpet anymore but others did on its behalf.

  "Roar!" "Roar!"

  It was at this moment that the enormous army behind the Mammoth was shown. The army was comprised of Mammoth Crocodiles, real Mammoths, and other creatures with the Mammoth bloodline.

  This was the same for the Dragon too. Behind it in the water hovered an army of Draconic Lizards, Draconic Eels, Lesser Dragons, and a myriad of other creatures with the Draconic bloodline.

  They were like the subjects of the 2 apex predators and at this moment, they could only watch helplessly as their leaders fought to the death.

  One last fire breath from the Dragon did it, the raging fire burnt through the Mammoth's flesh completely, taking the last of its HP with it.

  With an unwilling trumpeting from the Mammoth, the world around it started being upturned like it was in the middle of a whirlpool then an opening appeared and with a warping sound, its enormous bleeding body disappeared through it.

  It died, but it had last words to express its feelings.

  "Even though I died, Draco, I will come back stronger. The myth realm shall hear of my might again, and you shall be my first casualty".

  With that, it disappeared completely.

  After the Mammoth disappeared, all eyes turned to its followers that were left behind. The Dragon nor his followers showed mercy, they hunted the creatures like a group of cats hunting mice.

  …
Somewhere in Oceania, a crack seemed to have appeared in mid-water as what seemed like an enormous dead creature started falling from mid-water.

  The remnant will of the dead creature powered it, enabling the body to drift in the water for days, searching for the right heir to inherit the remnant powers stored in the body.

  A few days later, it dropped in a territory, it dropped in the territory of one of the current ruling sea kings, the Sea King who ruled beasts.

  …
[Ding! An opening to the myth realm has been discovered.]

  "Woah, bro, don't scare me like that".

  Out of nowhere, the system suddenly notified him of this, puzzling Sebastian. Of course, as he didn't know it, he had no intention of researching about it himself so he simply asked the system.

  The problem was that the system's reply left him speechless.

  [This information is locked, reach the requisite level before you can access the requirements to unlock it.]

  "…"

  "So why'd you inform me of it in the first place if you had no intention of telling me". Once again, Sebastian felt that urge to simply bonk some sense into the system.

  Well, right now, he didn't have the time to care about that because after swimming for minutes, he finally arrived in the Draconic Lizard kingdom.
