As the sun rises, the generals seize the ever-fleeting time, each beginning their own plans for the day. At this moment, they are no different from the common people aboard the Luofu.

"Oh? Does my little Miyabi know what it really means to be a hero?" 
"To destroy all the bad guys!" 
"Heroes aren't born to destroy, Miyabi. They're born to protect."

The dual planets were intertwined in each other's tragic destiny, dancing an eternal rondo around a pitch-black great sun. 
In the beginning, one of the planets gave rise to humans. These people looked down, and named the land below "Izumo." These people looked up, and named the world above "Takamagahara." 
One day uninscribed in the annals, the Yaoyorozu-no-kami descended from Takamagahara. These demonic beasts named Kami overturned the skies, burned the rivers and oceans, and shattered the land — People realized in horror that it was not an invasion for rulership, dominance, or plunder. The evil Kami came only to kill. 
As the planet stood on the brink of death, Izumo embarked on a Kami-slaying journey, exhausting the might of the entire country to slay the calamity "Sovereign of Revelation" and forging the very first Edict Edge using its bestial body. 
Giving the Kami a taste of their own medicine, the wielder of these swords can recite the mantra contained within the blade to master the divine power of Takamagahara, and use it to combat the evil Kami and save the masses. 
From then on, Izumo started its long and arduous crusade, exchanging inordinate lives lost for the fall of one Kami after another, shattering countless mortal blades to forge the twelve Sentinels. 
In the merciless fight for survival, Izumo used the might of the Edict Edges to light up their uncivilized world of darkness in less than ten Amber Eras, building cities of dazzling neon lights. 
That distant Takama Divine Realm, once so far away, became so close within their reach —
Yet history suddenly stopped there. The existence of the two planets instantly evaporated, disappearing into nothingness. 
Nowadays, the past of the border planet Izumo can only be gleaned from the scattered whispers in the universe. Academics hold various views regarding its disappearance, but none can solve the mystery. 
Izumo's history should have been a long flowing river, but it was severed in one cut, and all its past and future voided on emptiness' other shore. 
Did it never exist, and was it no more than a fabricated story? Did its histories never occur, and it ran aground on the beach of reverse causation? Was it yet another appalling experiment by Dr. Primitive, or was it a sign of the Voracity returning from the end of the Cosmos? 
Only that pitch-black great sun knows the answer, yet THEY remain silent, never speaking. 
Because everything that had happened will one day regress to the end, and everything that had ended is guaranteed to happen again. The universe undergoes an eternal recurrence under THEIR shadow, and Izumo is nothing more than the footnote for an ellipsis.

In the Year 4800 of the Star Calendar, the five lineages of the Vidyadhara made alliance on the Yuque, putting their sacred vow into writing. "This oath shall remain unbroken, standing stronger than even earth and steel." — History of the Xianzhou: Exodus of the Five Dragons.
 
In the Year 7379 of the Star Calendar, the Imbibitor Lunae Dan Feng caused turmoil that threatened the sacred wood. The Cloud Knights joined forces with the Vidyadhara Preceptors to assault him. — History of the Xianzhou: Cloud Knights War Records 
"Noble successor of the Azure Dragon, bearer of divine blessings from the heavens. Traversing clouds and bestowing rain, shaping forms as the world's essence beckons."
 
He dreamed of shouldering his responsibilities, performing the ritual dance gracefully, and sealing the Ambrosial Arbor. 
He dreamed of stepping into a battlefield where sharp blades and arrows fell like rain, and meted out punishment from the sky. 
He dreamed of being chained between jade pillars, pierced by long nails, sealed in darkness. 
He dreamed of wandering aimlessly in the darkness, chased by lurking shadows.
 
In all the dreams, he was a dragon, a hero, a sinner, but never a person with love, hatred, sorrow, or joy like everyone else in this world.

Year 7380 Star Calendar, Jingliu, the mara-stricken swordmaster of the Luofu, slashed her way out of Starskiff Haven, cutting through the Cloud Knights tasked to subdue her before vanishing in the mist of history.
 
Year 8096 Star Calendar, a young soldier named Yanqing rose to fame from the tournament hosted by the Seat of Divine Foresight, and was conferred the rank of Cloud Knight Lieutenant.
 
"The years pass in a flash, cups of wine the only solace."
 
A fleeting flash — thus is the speed of swift blades as the master and her student spar, and thus is the passage of the unceasing torrent of time.
 
Just how long has it been?
 
His duel with his master, centuries ago, still rippled like a memory from yesterday.
 
But the few years between now and when he took in the boy as his student felt like a lifetime.
 
Time gallops, swift as a stallion, sudden as a lightning strike, agonizing as a blade that runs him through. And yet, it feels like everything has always been the same.

Snow and ice are the children of the north wind and the sprites of the moonlight. 
In the last days of winter, let us cherish our holiday memories.
