​The Seven Great Powers are a group of legendary figures whose influence on the world is so profound that their very existence shapes the course of history. Each of these individuals possesses a level of power that transcends the ordinary, and they are known for their unique abilities and positions. Their identities and rankings can change over time as new figures rise to prominence or old ones fall. ​The First to be ranked is typically a figure of immense strength and reputation, often considered the strongest being in the world. The rest of the list includes individuals of various backgrounds, from legendary swordsmen and mages to mysterious, ancient beings. Their powers are often categorized as being on a level that can single-handedly turn the tide of a major conflict or defeat entire armies. ​The existence of the Seven Great Powers creates a hierarchy of strength that everyone in the world is aware of. Their actions are often a topic of global discussion and speculation. They are not a unified group but rather a collection of the world's most formidable individuals, each pursuing their own goals. Some are known for their benevolent actions, while others are feared for their destructive capabilities.

​In this world, magical and swordsmanship abilities are formally ranked to denote an individual's level of skill and power. For swordsmen, there are three primary schools: the Sword God Style, the North God Style, and the Water God Style. Within each style, ranks are awarded based on proficiency: ​Beginner: A swordsman with basic training. ​Intermediate: Proficient in the style's fundamental techniques. ​Advanced: Has mastered the style's core principles and can apply them effectively in combat. ​King: A master who has surpassed all others in their chosen style and can create their own unique techniques. ​Emperor: A swordsman of legendary skill, whose abilities can alter the course of battles and are known throughout the world. ​God: The highest rank, representing the founder of a style or a swordsman whose skill is considered divine. ​For magicians, ranks are also given based on their control over mana and the complexity of the spells they can cast. The ranks are similar to those of swordsmen: ​Beginner, Intermediate, Advanced: Standard levels of proficiency. ​Saint: A magician capable of casting spells of great power and complexity. ​King: A magician whose mastery allows them to create and manipulate powerful, unique spells. ​Emperor: A legendary magician whose power and influence can affect entire regions. ​God: The highest rank, often associated with beings of immense magical power or the founders of new magic. ​These ranks provide a universal way to measure an individual's power, and achieving a high rank is a mark of great prestige and influence.

​The Mana Calamity was a catastrophic event that occurred K417. A massive and uncontrolled magical phenomenon blanketed a large portion of the Fittoa Region on the Central Continent, causing an unprecedented teleportation of its inhabitants. ​Thousands of people, along with a significant amount of land, were instantly teleported to distant and unpredictable locations across the Six-Sided World, including the dangerous Demon Continent, the arid Begarritt Continent, and even the depths of the Great Forest. The event created a massive, scarred landscape known as the Teleportation Labyrinth, a place of immense magical instability and danger. ​The cause of the Mana Calamity is shrouded in mystery, with many attributing it to a failed magical experiment or a divine curse. The aftermath of the event has had a profound and lasting impact on the world, creating new heroes, fostering political turmoil, and leaving many families shattered and separated. The search for the teleported is an ongoing effort, and for many, the Calamity is a constant reminder of the unpredictable and dangerous nature of magic.

​Before the current age, the world was shaped by the conflict between six Great Gods. The Dragon God, a powerful being of immense strength and pride, ruled over the Dragon World. The Human God (Hitogami) was a cunning and manipulative deity who specialized in using people to achieve his goals. The Demon God, a being of great power and wisdom, held influence over the Demon World. The remaining gods—the Beast God, Sea God, and Heavenly God—each governed their respective realms. ​A great war erupted between these gods, forever altering the landscape of the world. The conflict was so devastating that the worlds of the Beast, Sea, and Heavenly Gods were largely destroyed or rendered uninhabitable. The survivors of these worlds were forced to migrate to the Central, Demon, and Millis continents. ​This ancient history is the source of many of the world's most powerful and dangerous relics, as well as the deep-seated rivalries and prejudices between the various races. The knowledge of this era is mostly lost to time, but its impact can still be felt in the political landscape and the lingering presence of powerful beings and artifacts.

​The world is saturated with Mana, a fundamental form of energy that permeates all living things and the environment itself. All living beings, including humans, possess a Mana Pool, which is a reservoir of this energy. The size and capacity of a Mana Pool can vary greatly between individuals. Mages and those with a natural affinity for magic have significantly larger Mana Pools, allowing them to cast more powerful spells and for longer durations. ​Magic is the art of manipulating Mana to create specific effects. Spells are typically cast by reciting incantations, which serve as a means to organize and direct the Mana. However, a select few can master "silent casting," where they visualize the spell's structure and effect without the need for a verbal incantation. This method is incredibly difficult and requires immense focus and control. ​Mana also exists in a more concentrated form within the environment, often crystallizing into valuable Magic Stones inside places with high Mana density, such as labyrinths. These stones can be used as a power source for magical devices or as a component in powerful spells. The concentration of Mana in a given area can affect both flora and fauna, sometimes transforming creatures into powerful and dangerous Monsters.

​The world is a single, massive sphere comprised of six distinct landmasses, each with its own unique history, climate, and dominant races. The Central Continent is the largest and most populated, home to the majority of humanity and several powerful kingdoms, including the Asura Kingdom and the Kingdom of the Dragon King. It is a land of great political intrigue and vast magical academies. ​To the east lies the Demon Continent, a harsh, desolate land known for its dangerous monsters and the powerful Demon Race. Life here is a constant struggle for survival, and only the strongest can thrive. in the Southeast, The Millis Continent is a hub of religious fervor, where the teachings of the Millis religion hold sway. It's a land of sprawling cities and ancient pilgrimage routes, with a significant population of humans and beastmen. in the Southwest ​The Begarritt Continent is a vast desert wasteland, primarily known for its deadly labyrinths, which are dangerous mana-rich dungeons. in the very north, The Sky Continent is a land suspended high above the others, home to the Sky Race and known for its unique, floating islands. Finally, the Ocean Continent is a mostly submerged landmass where the Sea Race resides. ​These continents are not easily traveled between, and the journey is fraught with peril. The very fabric of the world is shaped by a history of great wars and catastrophic magical events.
