World

This is a list of stories. They detail the lore of Gate Ruler.

Story 01
【Gate Ruler】 is set in the near future, where our world has been attacked by an extradimensional enemy known as the

【Exvaders】. Though their initial invasion was driven back, it was clear that they would soon return in force.



Fortunately for humanity, they are not alone in standing against this threat. Various nations have set aside their differences to form grand coalitions. Also joining them are supernatural beings of myth and legend, who have suddenly remerged into physical reality. Visitors from other universes such as 【Volnar】 and the 【Wonderverse】 have come to offer their aid as well. These joint forces prepare for the inevitable onslaught of the Exvader's full might.

The key factor in this coming conflict are 【Gate Rulers】, individuals with the power to materialize physical copies of warriors, weapons, and phenomena from thin air, through the use of special cards. Their ability to manipulate dimensions and space-time are critical in stopping the extra-dimensional Exvaders. Players will play as one of these gate rulers, preparing for the coming conflict through mock battles with each other.

The factions that a gate ruler can call upon include:

【ATLAS (ATLantic Alliance Sentinels)】: This is alliance between major Western powers and the 【Ark】, a giant, extradimensional craft constructed from a dislodged continent. The Ark is crewed by refugees of other universes that were destroyed by the Exvaders. Supporting this alliance is the 【OWL (Old World League)】, a coalition of supernatural beings from Western tradition, such as vampires and werewolves. Since many of them rely on humans for sustenance, the extinction of humanity at the hands of the Exvaders would be against their interests. The primary strength of ATLAS lies in their incredible firepower, provided by state-of-the-art military arsenal.

Among the crew of the Ark is the 【Zoo Brigade】, a group of animal-like humanoids that have extensively upgraded their bodies with cybernetic enhancements. Led by their fearless leader 【Sergeant Major Buster Kong】, they seek nothing else than to avenge their destroyed homeworld.



【Yomajin Front】: A coalition between various nations of East Asia, such as Japan and China, along with their supernatural allies such as the 【yokai】. Their military technology is just as advanced as ATLAS, but they have a lot more experimental weapons that incorporate magic.

The remergence of yokai, supernatural entities of Asian tradition, caught many governments in the region by surprise. However, Japan was able to adjust quickly, granting their yokai full Japanese citizenship in no time. Many of them returned the favor by offering to join the fight against the Exvaders.

Tokyo is where the initial invasion by the Exvaders occurred, as marked by a giant sword that appeared from nowhere and lodged itself in the middle of the city. Even after the initial attack, the area is frequently plagued by Exvader raids, slipping in through small dimensional breaches. However, fighting these incursions have allowed the Yomajin Front to test their new weaponry in actual combat, further accelerating their development.



【Volnar】: A universe straight out of traditional fantasy, the lands of Volnar are populated by familiar races and creatures, such as elves, minotaurs, and dragons. Wars here are fought by swords and magic, the latter of which can rival Earth's most advanced weapons in terms of destructive power.

Some of the most powerful entities in Volnar are the 【Grand Dragon Pentarchs】, five god-like dragons of unrivaled might. 【Magvarius, Grand Dragon Pentarch of Inferno】, is one of their number.

The Pentarchs are opposed by the equally powerful 【Fell Dragon Quadrarchs】. One of the four, 【Vastorus Rex】, is working with unscrupulous individuals of Earth to gain even greater power for himself.



【Wonderverse】: A universe that resembles the sci-fi future imagined in our past, the Wonderverse is populated by intrepid explorers and strange aliens. The laws of physics here are quite malleable, allowing people to travel lightyears in a matter of months just because they believe they can.

Most aliens here are friendly, but not all of them are well-behaved. The 【Crimenauts】 criminal syndicate, led by their don 【Malevolus Prime】, are constantly scheming to take over the universe through petty criminal acts. One of their goals is to find the greatest of the Cosmic Relics, the fabled 【Galactic Grail】. However, their attempts so far have been repeatedly foiled by the artifact's protector, the mysterious 【Space King Arthur】!



【Exvaders】: The term is an abbreviation of 【"extra-dimensional invaders"】. Currently, not much is known about them, except that they have traveled through numerous different universes, leaving all of them utterly devastated in their wake. The nations of Earth have sent multiple diplomatic missions to the Exvaders, hoping to establish some kind of communication. However, each one has been ruthlessly massacred without exception. Their next target is our own universe, and the only thing that can stop them are 【gate rulers】 and their allies.



Story 02
The Day of Destiny

April, 2030CE.

The “Day of Destiny” had dawned upon the city of Tokyo. One impossibly giant sword and a horde of “Exvaders” suddenly appeared out of nowhere to attack the city.

For most, this event was already beyond their wildest imaginations. But it was only the beginning.

On one particular day in April, 2030CE, a colossal sword several miles long, far larger than what the laws of physics ought to allow, suddenly materialized in the sky above Tokyo. It heralded the arrival of an invasion force of “Exvaders”—short for “Extradimensional Invaders”. Their origins and nature were unknown, but there was little doubt that they were destroyers of entire worlds, and that our Earth was next.

As this unimaginable threat was poised to destroy the city, most people were frozen in shock and terror. However, there were those who instead sprang into action.

The Japanese Self Defense Force swiftly engaged the enemy with all it had, their brand new robotic “sky troopers” leading the charge. They bought precious time, allowing others to intervene to save the people of Tokyo.



From the rooftops of Tokyo’s skyscrapers, mages wielded their wands and created magical barriers to ward against Exvader attacks. Superheroes with various special powers, known as “ascendants”, rushed across the city to rescue civilians in distress. Cats suddenly stood up on their hind legs and began to talk, verbally guiding people to safety. Emerging from the dark shadows between buildings, the yokai—strange and quirky supernatural entities of Japanese tradition—also lent their aid in saving lives.

And those who halted the fall of the giant sword were the gate rulers, who revealed their existence to the world for the very first time. These individuals have special powers over time and space, allowing them to even open portals to other universes. Through their combined efforts, the gate rulers slowed the descent of the sword, causing it to land in the grounds of Yoyogi Park. Once there, they locked the sword in its current position, rendering it stationary and harmless.



Story 03
An Alliance Between Earth and Other Universes

Thanks to the gate rulers, the world was saved from being cleaved in half by the gargantuan sword. But the struggle was far from over.

Suddenly, a giant fracture appeared in the sky, and from it emerged an even greater swarm of Exvaders, led by a giant red dragon. The fight for Tokyo quickly developed into a full-scale battle. Later known as the Battle of the First Breach, Tokyo’s defenders were ultimately victorious, but the cost was high. The conflict resulted in the deaths of over 40,000 people, as well as the total destruction of three of Tokyo’s 23 wards.



But the threat of the Exvaders did not end there. Even after the Day of Destiny, smaller dimensional breaches would sporadically manifest themselves in the Tokyo area, subjecting the city to Exvader raids. And the influence of the Exvaders was not restricted to Tokyo, with strange phenomena taking place throughout the world. The worst among these was the complete loss of the Middle East, as the Exvaders trapped the entire region under a giant, impenetrable dome.

It was clear the Exvaders presented a continued existential threat to the whole of the Earth. The only hope for survival is for all of humanity to combine their strengths, along with all the help they can get from allies in other universes. And so, four factions joined forces to defend Earth from total annihilation. A new age of strife had begun, and it would be unlike anything ever before witnessed on Earth.

The Four Factions Opposing the Exvaders



ATLAS—a hybrid force that combines the past and the future

ATLAS is a faction that combines powers of old magic with the wonders of the latest technologies. Its forces wield the most advanced military arsenal developed in the United States and Europe, while also making extensive use of revived ritual magic and alchemy. They are joined by various supernatural beings of myth and legend, as well as refugees from other universes destroyed by the Exvaders.



Volnar—a fantastical world of swords and sorcery

Volnar is a world in another universe which has been fighting the Exvaders for ages, long before they had attacked Earth. While it is a fantastical realm devoid of modern weaponry, its mighty warriors and spellcasters more than make up for this lack. Volnar is home to humans, elves, beastfolk, dragons, and many other races and creatures, most of which are eager to help fight the Exvaders.



Wonderverse—a universe of adventure, wonder, and mayhem

The Wonderverse is a universe where the laws of physics work somewhat differently (and much less predictably) than ours. It features a wide variety of inhabitants, ranging from space superheroes, giant robots, and alien crime syndicates. The only constant of the Wonderverse is to always expect the unexpected, as its unpredictable nature is reflected in the way its residents do battle.



Yomajin Front—a coalition of humans, yokai, monsters, and gods

The Yomajin Front is an alliance formed by the nations of Eastern Asia to defend Japan, which continues to be the primary focus of Exvader aggression. It includes the Japanese Self-Defense Force, who have become veterans at fighting against the Exvaders over the years. They are aided by various supernatural entities that reside in the region such as yokai, along with experimental weapons such as giant robots and mechanical dragons that tower over the battlefield.
