In the far distant past when the world was just created, the Ancient Ones built the Celestial Palace above the Sanctum Island in the Sea of Hope.
The island was a part of a submarine volcano. Submerged rocks and atolls were strewn all over the vicinity of the island, and the waters nearby are often shrouded in dense sea fog, which caused the wreckage of many ships that ventured to pass by.
Remote and undisturbed, the island was the ideal location for Ancient wonders. The Ancient Ones set out to build temples and workshops with their incredible skills and technologies. When the Celestial Palace began functioning, the mechanisms of the temple on the island received energy waves from the palace, and thus the island on the ground started coordinating with the palace above the sky.
Before the Endless War broke out, the Ancient Ones attempted to control the orders in the Land of Dawn. They sent and to arrest unruly Evil Gods and imprison them in the Temple of Thunder on the Sanctum Island, where a priestess loyal to the Ancient Ones would drive her Mecha Guard "Phylax" and keep watch on them.
The Mecha was fueled by Primal Lightning, a unique magic that could control lightning bolts with the Ancient power, and could only be performed by those specifically created by the Ancient Ones. Among them are and high above in the Celestial Palace, as well as the priestess down below on the Sanctum Island.
The priestess was named . She accepted the eternal youth and divine power granted by her masters and punished the prisoners with ruthless Primal Lightning. Hearing her name alone could make the most powerful Evil Gods tremble in fear.
After the Endless War broke out, however, the Ancient Ones vanished from using the Twilight Orb to seal the darkness and light. , the immortal Primal Warden, fell into a deep slumber as her masters disappeared.
Times changed, and some shipwreck survivors appeared on the Sanctum Island. These impoverished people were struggling to survive on the barren island, and many trudged across the island only to find scarce resources.
After a devastating earthquake, the ruins of a temple were revealed. It was buried deep in the valley and scorched by lightning strikes. When foraging for metal scraps, an old rag-man discovered the place, but what he found instead was a blond girl lying in the rubble. She could be struck by lightning at any moment!
The old man risked his life and carried the girl back to the seaside fishing village. Having been injured in the head, the girl could only remember her name—. The childless old man took her in, and together they lived in the small village.
's foster father doted on the daughter that he miraculously found, and spared no effort to care for her. could stroll around in the village when she didn't have to help with the chores, but the old man had one rule: she couldn't go near the valley—he had a hunch that one day he would lose his daughter there...
When was bored, she would often gaze up at the Celestial Palace above—the villagers said that it was the temple of the gods, and sometimes she could see bizarre birdlike people gliding across the sky with lightning. But every time she saw them, a strong feeling of unease would fill her heart, for the past she'd forgotten seemed to be connected to the lightning sparks. So, she would always run back home and bury herself in her father's arms, calming down as the old man patted her hand.
Ten years passed, and the old man became frailer. The other kids all grew up, except for who remained as young as when she was first found.
Eventually, her foster father was too old for physical labor. In order to survive, he had to break the rule that he set up himself—he brought with him to pick up metal scraps in the ruins of the valley.
Having searched the outside in vain, the old man had to take the risk and step inside the temple with . As they walked deeper within, felt that her memories were surfacing once again, and suddenly lightning struck as giant flying blades were shot at her father! dashed forward and instinctively stopped the blades with her power, the blades plunging into the ground and splitting rocks with lightning sparks.
Amidst the fire and dust, an Elemental Giant in gold armor appeared in front of , "You left your post, !"
This was—, the Guardian of the Celestial Palace! At that very moment, countless memories flooded 's mind: the Ancient Ones, priests and priestesses, the temple, Evil Gods... She screamed to reject the memories, but her mind was already engrossed in the past: the earthquake accidentally awoke me from my slumber, and it was the old man who raised me when I barely knew anything...
"Die, invader!" waves his giant arm at the old man, a string of flying blades shooting at the ground! Quick as a flash, "Phylax" came as summoned and reached out its strong metal arm to catch the blades.
spoke from "Phylax" the Mecha, "Let my father go."
shouted at the Mecha in front, "Traitor!"
And calmly replied, "Or let's fight to the death."
Among the temple ruins in the depths of the valley, and were locked in a fierce battle, roars of thunder echoing in the mountains as lightning strikes crashed against each other, shattering the stone pillars and statues.
While the two were still in a deadlock, a birdlike Guardian of the Celestial Palace— closed his wings and descended upon the ruins, "Stop the foolish fight! The Celestial Palace is in peril!"
They looked up at the sky, and as expected, couldn't sense the energy of the holy city anymore. And soon, pieces began plummeting from the sky—in the blink of an eye, the great Celestial Palace started to collapse!
Since the palace fell, the temple on the Sanctum Island could no longer receive energy from above, and sealed Evil Gods started to flee.
commanded in a thunder-like voice, ", we shall stay and fix the seals! , arrest the Evil Gods!"
To that answered, "I understand my duty. Let me send my father back first!"
and stayed behind in the valley of the temple to watch over the rest of the Evil Gods, while drove her "Phylax" and took her foster father back to the village.
As stared at her senile and shaky father, she couldn't hold back tears running down her cheeks. After ten years of living with a family, she was no longer the cold and heartless Primal Warden.
I'm his only child, his hope for the future. How will he go on living if I leave now?
But the land was facing new crises due to the fall of the Celestial Palace. had to fulfill her duty as the Warden and hunt down the escaped Evil Gods.
Farewell, dear father! Please trust me, I will one day return to you...
I promise!
drove "Phylax" and flew toward the Land of Dawn.
Later, a lot of people across the Land of Dawn would claim that they had seen a giant Mecha Guard. Every time an Evil God wreaked havoc in the world, and her "Phylax" would be there in an instant, punishing the dark forces without mercy.
In between battles, the girl would detach from "Phylax" and gaze at the far distant northeast. Across the horizon, mountains, rivers and seas, on the remote island, an old man would also be looking longingly at the direction of his daughter...
