The Definitive timeline for the 7 Seals verse from its inception to its destruction.
The Time before the very concept of Time, when the Forces of Chaos ruled over what was Yggdrasil. Creation was formless and only abstract concepts existed, this age was marked by chaotic events and distortions in What Is and What Isn't as Reality had not yet been declared.
Ymir, the very first Mage to ever exist, ends the Age of Chaos by declaring Reality and expelling the Forces of Chaos out of Yggdrasil, separating What Is and What Isn't with The Veil. And, with this, Ymir begins the Dawn of Man, when intelligent Mortal life can begin to grow.
Ýmir slept for 22 cycles after the Declaration of Reality and only awoke to find himself in a strange land, a vast and icy Realm. This land would come to be Ýmir's home and later be known as Jötunheim. Ýmir was a primordial-esque being of Chaos and could reproduce asexually. From his armpits, he bore two others of his kind, a male and a female, and from his legs, he bore a great being with six heads. Made in his own image, Ýmir dubbed them the Jötnar and declared Jötunheim as their home, without challenge.
Rādius crafts his own Dimension-Reality fundamentally built from his own power the Radiance, a magnificent Realm of Radiance, where the Sun never set, a realm he dubbed Lysheim. Nocji also did the same, crafting her own Realm she called Mørkheim, where the moon never fell, a Realm of Darkness.
Jonathan Chambers, a Wizard, and husband to a noble night tries to peer through the Veil with his Majiks and has his mind tampered with by the Forces of Chaos, driving him to insanity. His wife, Uther Pendragon, was forced to kill him after he tried to drown their son Authur in his madness. Jonathan's death is what led Uther to establish an Order of Knights who would research the Veil and make sure these Chaos beings never escaped, eventually founding the Knights of the Iron Order.
Arthur Pendragon, Ⅵ. Supreme Commander of the Iron Order suffers a great tragedy when his eldest son, Llachu, is slain by his other son, Mordred, after being driven to insanity by the Forces of Chaos. Mordred fleas Planet Britainia, leaving old King Arthur alone on the throne.
Old King Arthur descends into Chaos itself to rescue his beloved son Mordred from the grips of The 7 Deadly Sins. A great battle ensues where Arthur allows Mordred to kill him if that is what it will take to save him. Mordred comes to reconcile with himself and his actions before turning on the Sins. The boy just narrowly escapes with his life and returns to the Iron Order with Arthur's body in shame. He has killed his own father.
The 7 Deadly Sins, agents of Chaos, bring about the end of the Multiverse, yielding the birth of a new World Seed which they aim to use to birth a new Reality rooted in Chaos without The Veil to imprison the Forces of Chaos. They go to war with the Iron Order over the World Seed and over the fate of the next reality. In the end, it is Sir Kejuan Ruckur who obtains the World Seed and aims to birth a new reality where only fated events happen by manipulating the Chains of Fate with an invention of his own, his Story Machine. He fights with Sire Sorahōka Josefumi over the seed and ends up killing his brother-in-arms. Kejuan consumes the World Seed and with it, births a new Reality, one where The Veil is re-employed to ensure the Forces of Chaos cannot escape and their influence cannot infect his new creation.
Once the New Reality is born in Yggdrasil, the two primordial forces of Magic, the Darkness and the Radiance declare war on each other. This battle rages across the Multiverse and burns entire Realms in its wake. This event is referred to as The Great War and lasted 76 thousand cycles. This conflict threatened to weaken The Veil, undoing Ymir's work, and inviting the Forces of Chaos back into Reality.
The Forces of Chaos make a Sacred Vow to destroy the Veil, kept with 7 Sacred Seals, the exchange for the vow. If broken, the Forces of Chaos will be let back into a new Reality to corrupt. Four exceptionally powerful Knights of the Iron Order take it upon themselves to see that the Seals are maintained and to punish those who would break them. They make their own Sacred Vow with the Seals, granting them unimaginable power to only be summoned and wielded against those who break one of the Seals. These Four would come to be known as the Four Horsemen of the Apocalypse. Kejuan, now with the power of the World Seed, creates the Realm that would later become World's End and begins work on his Story Machine to manipulate the Chains of Fate and to reinforce The Veil as a failsafe should The 7 Deadly Sins succeed in breaking all 7 Seals.
Rādius, King of the Gods and Light, declares war on Nocji, Empress of the Oni and Darkness.
Sorahōka Josefumi, brother-in-arms to Kejuan Ruckur, wakes up on a desert world in the middle of an intense battle between Angels and Daemons. He somehow survived his fight with Kejuan and made the trip to the new Reality. Josefumi rejoins up with the Iron Knights to locate Kejuan and put a stop to his plans to build the Story Machine.
Sir Kejuan finishes his Story Machine and, in combination with the Chains of Fate, uses it to take full Narrative Control of the Multiverse. With this power, he ends The Great War and claims superiority over all of Yggdrasil. This marks the end of history's bloodiest conflict and free will.
The Unmei (Fate | Destiny) Period is a massive strand of time in the new Reality where the Author ended the Great War and kept the Forces of Chaos at bay with his Story Machine and the Chains of Fate. This was a period when all events were scripted and like gravity, fate pulled things together. The Author ruled the Multiverse with this power for a little over 2 Million Years
Mahadaji Z. Al-Hashimi rebels against the Empire with his close friends and allies, pushing his Brahma, Eyes of Creation ability to their limit in his fight with an Imperial Champion. After this takes place, Mahadaji establishes the House of Al-Hashimi and declares his 1st Dirka'Ad, beginning his conquest of various worlds and systems.
Mahadaji Z. Al-Hashimi's first son is born just one year after he creates the House of Al-Hashimi. He names the boy Jatayu Al-Hashimi.
On the Planet Heveuhiri, Lucifer Morningstar confronts the Kirtsan in an effort to draw out Mahadaji Z. Al-Hashimi and take the 9 Sacred Jewels from him. While this does draw out Mahadaji, he proves far too powerful for Lucifer to handle. Mahadaji, bored of the fight, defeats Lucifer with a Magic Clone of his containing only a 4th of his power and skill. Mahadaji takes and seals away both of Lucifer's Radiant Virtues, Holy Fire and Divine Light, before restraining him and using Brahma, Eyes of Creation, to banish the fallen angel to the 1st Dimension. Lucifer's Holy Fire and Divine Light were sealed in ancient pots and used to make the House of Al-Hashimi even stronger.
Jatayu Giovanni, the wayward and disgraced son of Mahadaji Z. Al-Hashimi, returns home to Risauyama to confront his father for the death of his two sons, Lucio and Bruno, whom the Kirtsan killed. Jatayu and Mahadaji fought and despite Mahadaji having superior abilities and being a Great Mage Equal to Heaven, Jatayu defeated and killed his father. This victory was short-lived as he too would sub com to his wounds and die in the vastness of space.
Sayana Al-Hashimi earns the title of the Most Dangerous Bounty Hunter in the Universe after he unlocks the final evolution of his Inherited Technique Shiva, Eyes of Destruction, allowing him to destroy any kind of energy, no longer just limited to Magical Energy. Sayana uses this newfound power to carry out a hit on serval high-ranking officials of the United Stellar Commonwealth, marking him as their great enemy.
Vijaya Al-Hashimi is born to the House with Brahma, Eyes of Creation, the 2nd person to ever be born with such an Inherited Technique. Not underestimating the threat of their bloodline, the United Stellar Commonwealth launched an attack on their Homeworld, Planet Risauyama, glassing the world and killing Vijaya before she can become a threat. This marked the fall of the House of Al-Hashimi as a Universal Power within the Cosmos as the Commonwealth began to hunt down and exterminate the bloodline to ensure another with Brahma could not be born. This genocide was justified as seeing the Al-Hashimi as particularly dangerous to all life in the Universe.
Balthazar O. Skyburner II & Sorahōka Josefumi fight and defeat The Author @ World's End. Balthazar destroys his Story Machine and uses Supreme Grade Sword: God Shattering Star to shatter the Chains of Fate. While this does free the Multiverse of the power of Fate, it weakens the Veil that was preventing the Forces of Chaos from returning to Yggdrasil.
