The planet Earth came into a new era as technology began developing at an astonishing rate in the last few centuries. The humans began developing starships and as time progressed we became a beacon of hope and a pillar of stability throughout our known galaxy. Our planet was considered a strategic location as advanced infrastructure were soon built making it a hub for interstellar diplomacy and trade, attracting delegates and merchants from distant corners of the known galaxy. 

We established the Intergalactic Trade Center on Earth which served not only as a testament to our economic prowess but also as a symbol of our commitment to fostering peace and unity among the stars. In time we gained the attention of the Galactica Star Federation. The Galactica Star Federation began a mentorship with Earth as they taught our leaders how to skillfully navigate complex political landscapes, mediating conflicts and brokering alliances that ensured the galaxy's prosperity. 

This era of collaboration gave rise to a new galactic culture, one that celebrated diversity and encouraged the exchange of ideas and resources among other civilizations. Earth's influence extended beyond politics and economy; its cultural and scientific contributions enriched the galactic community, echoing humanity's enduring spirit of curiosity and our humanity as we strived to make it a better place for everyone. 

During the last century the people of Earth lived in relative peace and harmony with the galaxy as we became more prosperous, But this all changed one day when fugitives from the Galactica Star Federation made their way to our side of the galaxy. They stumbled upon our star system and after learning about our great success in how we fostered harmony and prosperity with the rest of our galaxy, they made a declaration of war against us. 

They chose planet Earth as their first target since we had become an Intergalactic Trade Center within our galaxy. We possessed great resources and could have assisted them in their time of need if only they had reached out to us. We were the first of many planets they had planned on eliminating within the Galactica Star Federation alliance. 

Led by professor Alistair and her cadre of malicious comrades who originated from a sector deep within the alliance territory known as Squidtopia. With her twisted genius and unparalleled intellect, she used her vast intelligence to enact revenge against the Galactica Star Federation for neglecting to assist her people. She had been planning these attacks on the alliance for quite some time. 

After the great famine that struck their home world Squidtopia, causing great loss totaling in the billions, the remaining population of Squidtopia joined forces with professor Alistair as she sought revenge. She led them against the planets in the Galactica Star Federation who refused to assist them after being given many opportunities during the past twenty years. They gathered around our planet and launched a multi-pronged assault against the Earth's defense system. Utilizing a blend of advanced technology stolen from other races, they used this technology along with brute force as they systematically dismantled the planet's security networks. 

Their coordinated strikes were not just limited to physical attacks, but also cyber warfare to cripple communication systems. Their attacks created chaos and confusion among Earth's military defense. This sinister coalition was united under Alistair's vision, a testament to her persuasive prowess and leadership skills among these rogue outlaws. Squidtopia united front presented a formidable challenge, the likes of which Earth had never experienced before. 

Squidtopia utilized Hundreds of Galactic Scout Starships that they had collected over the past few years and descended upon Earth. Their primary objective became locating an enigmatic artifact known as the Planet's Heartstone. They learned about this sacred artifact from Professor Alistair who once served as an archivist for the Galactica Star Federation alliance. 

She had been trusted with safeguarded forbidden knowledge that had been deemed too dangerous for the public. She used the knowledge that she gathered from her experience and was able to devise a plan to locate the artifact. Without realizing the artifacts significance to the planet and its health. She made it their life goal to steal it. The Heartstone had been previously shrouded in mysticism, said to embody the very essence of the planet and, according to ancient lore, exists as a part of every planet hidden within the elusive Spiritual Realm, a dimension that transcends our conventional understanding of known reality. 

Upon successfully breaching the defenses of this Spiritual Realm, Alistair and her cohort managed to abscond with the Planet's Heartstone. This very act of theft sent shockwaves through the fabric of reality itself, instigating unprecedented environmental and climatic disasters across the entire planet. The seas churned with such fury, volcanoes erupted with intensified anger, and storms raged with newfound vengeance. It was as if the planet itself was mourning the loss of its heart, its Heartstone. 

Soon after the planet became cloaked in enigmatic, swirling clouds that shimmered with a spectral brilliance that casted an otherworldly glow over the lands below. This phenomenon signaled not just a shift in the environment, but a transformation in the very essence of reality as we knew it. 

This happened within hours of the theft the entire planet reverted to a prehistoric state. It restored life to creatures that were believed to have been long extinct as the ground opened up from the sudden earthquakes causing a world wide panic which resulted in many deaths as people fought to escape. It was as if billions of animals around the planet Earth expressed their fear for what would be coming next. 

At that very moment every animal stopped suddenly and looked up towards the heavens. Even the marine life that lived in the deep sea below and the animals who dwelled high within the sky above did the same. 

Every animal around the planet anticipated what would come next. Expecting chaos to emerge from this disaster that covered the planet as it unraveled, the catastrophe of losing the planets Heartstone changed something within the Earth as it grew in strength from this experience. These changes moved the wild animals and plant life up in the food pyramid. At that moment little did any human realize that life on planet Earth was never going to be the same again for any of us, but that didn't matter because none of us were ever going to be around to realize the changes that were coming our way. 

When the clouds had begun to settle around the planet the inhabitants of Earth soon found themselves alongside entire continents being drawn away from their former realm and thrust into entirely new realms, where the boundaries between the mundane and the magical were now blurred. 

At first, the people of Earth after waking up in this newfound realm were overwhelmed with great fear and confusion. Many of them chose to succumb to their fear rather than face the unknown challenges that lay ahead of them. 

In the coming months the humans, despite the cosmic upheaval they faced, banded together as they embarked on a journey of discovery unlike any other set before them. After learning how to adapt to their changing environment as they found their purpose and resolve. As they began their arduous quest to reclaim the planet's stolen Heartstone. 

Their journey was fraught with challenges, from navigating the altered landscape of their own lands to forging alliances with beings from realms once thought to be mere legend. These college students from Garcinia Institute, although numbering only in the hundreds, acquired newfound powers along the way, using a system known as the "Card Battler System." 

Those who were able to utilize this Card Battler System became known as Card Battlers. With these newly acquired powers they were able to confront whatever challenges that came their way. Along the way, they meet with the previous citizens of Astra, a race of powerful beings known only as the Ancient Ones. A highly advanced civilization steeped in mystery and power beyond their mere mortal comprehension. 

These Ancient Ones had lived in this strange realm undisturbed for the last hundred years. They foretold ancient stories of how they arrived on this realm after fleeing from others much like themselves. Along with ancient beings that had been sealed away hidden behind something known only as the Central Finite Curve which was said to separate their realms from the lost and forgotten realms. 

Their stories created great confusion among the people as they tried to understand their warnings. Unable to understand the great danger that the stories warned of, they continued to press on. The students quickly realized that whatever secrets these ancients were hiding could be vital in helping them return to their own realm, but only if they could gain access to this incredible knowledge that they possessed. 

Ultimately, the group of adventurers found success in gaining favor with the Ancient Ones and learning their secrets, including how to forge something ancient known as Relic Keys. With that newfound knowledge, the students became like the Ancient Ones. Soon they gained incredible powers and wisdom allowing them to forge greater Relic Keys which they would later use to return safely to their own realm of origin. 

Guided by the hope of restoring Earth to its former glory and the urgency of their quest, the Card Battlers set out towards the horizon. Alistair and her forces were rumored to be on a small remote island fortress just off the coast. After arriving on the island in their own sky ships they fought the professor and retrieved the Earth's Heartstone. Soon after they realized without her help that they wouldn't be able to return the Heartstone to the Spiritual Realm. After retrieving it they enlisted the help of Professor Alistair and her remaining forces. Before long the Card Battler's and Professor Alistair remaining members made their way back to Earth after crossing many realms. 

This transition marked the beginning of an entirely new era. The era of the Gatekeeper Hunters. With this newfound knowledge they acquired previously from the Ancient Ones, they forge Relic Keys which allowed them to access ancient powers that were said to have been sealed away by time. They soon found a new mission to locate the Gatekeepers, another ancient race of beings that safeguarded the gateway to the lost and forgotten realm, a sanctuary of sorts lost to the realms long ago during their creation. 

When the Gatekeeper Hunters returned home, these brave individuals discovered that much time had passed since they left the planet they once called home. The planet had undergone drastic changes reverting to a prehistoric era, and everything they thought they once knew was gone. After many failed attempts to reach the exclusive Spiritual Realm they soon realized that it was no longer possible to return the planet's Heartstone. 

This new era that they faced together was fought with courage, and many sacrifices along the way. They encountered beings thought to only exist in mere legends that shouldn't have even existed here on Earth yet still be alive to this day. They faced off against many deities including the Gorgons sisters, and the fallen titans that were believed to have been sealed away. 

These dangers they faced tested their resolve against their former home Earth which had been reborn from the chaos giving life to many other ancient creatures including dinosaurs, and the infamous Atlanteans which were believed to have gone extinct millions of years ago. 

So began an epic journey as they strived to survive the alternate environment that once was their home. Until the day they would once again leave as they developed new Relic Keys that allowed them to travel into alternate realities in search of the Gatekeepers along with another version of Earth that they could one day call home. 

The remaining survivors of Earth known as the Gatekeeper Hunters set off after realizing that they could no longer inhabit this planet anymore. Many ventured throughout the multiverse along the way they faced many great dangers. They soon encountered evil alternate versions of the Ancient Ones. These vile monsters sent a great number of Relic Hunters after them. These alternate versions chased after many Gatekeeper Hunters throughout the entire multiverse without rest or stopping. 

It wasn't long before the remaining Gatekeeper Hunters found themselves on the run as the enemy's number kept growing with each member that they captured and converted. It wasn't long before they reached the Central Finite Curve that separated their realms from the forgotten realms. A place that even the Relic Hunters themselves feared a place where the sealed realms laid away locked behind a terrifying gateway marked with an ominous dark aura and cryptic warnings. 

With nowhere else to go they dared to press forward as they broke though the hellish gateway unleashing a terrifying presence that even the Relic Hunters feared as they entered the domain of Hella, an immortal being whose presence once upon a time could rewrite the fabric of reality itself bending it to her darkest desire. As they unleashed the once sealed realms they returned to their rightful place in the multiverse as they started returning the Central Finite Curve revealed something else hidden behind them another realm full of beings with great powers beyond their mortal comprehension.
