By the 23rd century, Earth had entered a new golden age. Through rapid technological advancement, humanity developed starships capable of deep-space travel and gradually positioned itself as a stabilizing force within this known galaxy. Earth evolved into a central hub for interstellar diplomacy and commerce, eventually becoming home to the Intergalactic Trade Center, a symbol of humanity's economic strength and its commitment to peace among the stars.
Earth's rise did not go unnoticed. The Galactica Star Federation, a powerful union of planets governed under a shared constitution, recognized Earth's potential and welcomed it under their guidance. Through this mentorship, Earth's leaders learned the intricacies of interstellar politics, conflict mediation, and alliance-building. Over time, a new galactic culture emerged—one built on cooperation, shared knowledge, and diversity. Humanity's influence extended beyond trade and governance, shaping science, culture, and diplomacy across the Milky Way.
For nearly a century, peace endured. That peace would soon be shattered when factions from within the Galactica Star Federation turned against Earth and the Milky Way galaxy. Motivated by envy and resentment, these enemies launched a calculated war on their solar system. Leading them was Fleet Commander Alistair, a brilliant scholar-turned-strategist from the ruined sector of Squidtopia. Though once devoted to knowledge and progress, the destruction of her home world hardened her resolve, driving her toward vengeance against those who had been given so much while her people were given nothing and left to suffer.
Under Alistair's command, the attacking forces deployed overwhelming military strength alongside advanced cyber warfare, crippling Earth's defenses. Amid the chaos, Alistair secretly descended to the planet in a small scout vessel. Her true objective was not conquest, but the theft of an ancient and sacred artifact hidden deep within Earth's core Earth's Heartstone.
The Heartstone was more than a source of power. It was spiritually bound to Earth itself, linked to a higher Spiritual Realm and embodying the planet's very essence. Using specialized extraction technology, Alistair succeeded in removing the Heartstone, but the process fractured it. As shards were scattered across the known realms as the planet reacted violently to its loss.
Earth descended into catastrophe. Massive storms, earthquakes, and volcanic eruptions tore across the globe. The skies darkened, spectral clouds filled the atmosphere, and civilization collapsed within hours. As the planet struggled to survive without its core essence, it reverted into a prehistoric state. Long-extinct creatures returned, ancient ecosystems resurfaced, and the natural order was rewritten. Humanity became scattered, confused, and powerless to defy it.
As Earth mourned, a cosmic storm ripped entire continents from reality, casting them into a fractured realm where discarded worlds and forgotten realms collided.
Among the survivors were students from the prestigious Garcinia Institute. Lost within this strange realm, they encountered an ancient race known as the Relic Hunters. These beings revealed the existence of the Card Battler System, a mystical power embedded within the realm itself. Through discipline, sacrifice, and survival, the students learned to harness this power, becoming known as Card Battlers.
Raymond, one of the survivors, endured a year-long journey across the Island of Ethereal, facing constant danger and loss. Through perseverance, he earned the respect of the Relic Hunters, who deemed his group worthy of their ancient knowledge. They taught them how to forge Relic Keys, powerful artifacts capable of unlocking hidden realms and creating a gateway between this realm and their own.
Armed with this knowledge, Raymond and his comrades sought to defend humanity while exploring deeper within the unknown realm of Astra. Their goal was clear from the start: reclaim the scattered fragments of Earth's Heartstone and restore their home world before the damage became irreversible.
Their journey culminated in a confrontation with Fleet Commander Alistair on a remote island fortress. Though the Card Battlers succeeded in recovering most of the Heartstone fragments, they soon realized that returning them to the Spiritual Realm would not be possible without Alistair's knowledge. Forced by circumstance these former enemies formed an uneasy alliance, setting the stage for an uncertain future.
Book Two Summary
After crossing countless hostile realms and enduring devastating losses, the Relic Hunters and their comrades finally returned to Earth. What they found when they arrived left them devastated and the world they once knew was gone.
Earth had regressed into a savage prehistoric wasteland. Civilization was now on the brink of extinction while ancient ecosystems replaced their own and now colossal beings ruled over them. Among them was Thokk, an armored titan whose presence dominated the Wildlands. His thunderous footsteps echoed across the entire land, striking fear into every surviving settlement. Other ancient forces that had long been sealed away, had also awakened in response to the planet's instability.
Despite having recovered most of Earth's Heartstone fragments, efforts to restore Earth failed repeatedly. Fleet Commander Alistair, using every method at her disposal, attempted to return the fragments to the Spiritual Realm. Each attempt was rejected. The spiritual connection that once sustained Earth was severed completely, as if the planet itself refused salvation.
Upon learning that the Galactica Star Federation had withdrawn its support, declaring Earth too unstable and dangerous to engage with. Humanity had been abandoned by the Galactic Star Federation.
In this new age of survival, the Relic Hunters became Earth's last line of defense. The planet was plagued by ancient deities once sealed away, including the Gorgon Sisters, whose gaze could turn living beings to stone; Fallen Titans of immense power; and the monstrous Atlanteans, reborn amid Earth's chaos. Dinosaurs and forgotten wild beasts reshaped the food chain, pushing humanity closer to the brink of extinction with each passing year.
Through constant conflict, the survivors forged stronger and more refined Relic Keys, adapting to Earth's ever-changing landscape. Yet with every battle won, it became increasingly clear that survival alone was not victory.
Eventually, the survivors faced a sobering truth: Earth was no longer a sustainable home. Even with the aid of the few remaining Galactic Star Federation members who stayed behind, the planet could not be reclaimed. Reluctantly, humanity chose to abandon its birthplace and seek refuge elsewhere.
The Relic Hunters from Astra taught the next generation how to forge more of these advanced Relic Keys using the remnants of Earth's shattered Heartstone. These new keys could only be wielded by those whose essence had been bound to them, allowing passage between the alternate realms as they searched for another version of Earth, one untouched by this devastation in hopes of finding the life they once left behind.
Book Three Summary
As humanity fled across the vast multiverse, visiting countless alternate realms before encountering twisted, corrupted versions of the ancient beings known as the Relic Hunters, these dark reflections relentlessly pursued humanity, capturing survivors and stealing their knowledge. With each capture, the enemy's forces grew stronger, learning to forge more advanced Relic Keys.
Constantly on the run, the survivors were pushed to the brink of extinction. Their flight carried them to the edge of the known multiverse, the Central Finite Curve. Beyond it lay the Forbidden Realms, sealed away by ancient entities born during the dawn of time. With no safe path remaining, the survivors chose to break the sacred seals.
In doing so, they unleashed a force far beyond their comprehension: the Dark Domain of Hella. Her very presence could warp entire realms and alter reality itself threatened the balance of the multiverse itself.
Despite the growing danger, the survivors gathered the remaining shards of Earth's Heartstone that were scattered across countless realms and gathered them in order to forge an artificial Hearthstone to replace theirs. Upon returning to Earth, life slowly began to return as the lands became fertile and hope was restored to their broken world.
Unaware of the consequences of their actions, the survivors looked toward the future, unprepared for the new threats that now stirred across the known realms causing untold havoc.
