In the long river of time, we are all prisoners. The linear law is an invisible shackle, pinning every life to a one-way journey on the rack of fate. From the moment we are born, we are destined to trudge toward our end.
And The Sky Menders' Sequence tells the story of a thousand-year pact to resist this fate.
There are no myths of immortality here, only "consciousness programs" encoded in the folds of spacetime. They are contracts etched with the lives of the Guardians. The Guardians have long since become stardust, but their determination to protect was forged into commands that trigger automatically: whenever the thing they guard faces catastrophe in the river of time, the program awakens at the most logical point in spacetime and seeks a "vessel" in which to take root.
It might be a soldier gripping his spear amid the flames of war in the Warring States period, a resolve not his own suddenly flashing in his eyes. It might be a painter holding a brush in a Renaissance studio, a symbol from a thousand years in the future appearing on his canvas by chance. The vessels differ, and none remember their former lives, but the core command burns like an undying spark in every body, kindling the same sense of duty.
Individuals will eventually vanish, but the "relationships" and "responsibilities" defined by the pact weave an immortal circuit through spacetime.
When the physical laws of the universe are cold as iron, and the extinction and birth of all things follow formulas that brook no argument, humanity still insists on using the faint light of consciousness, the warmth of emotion, and the weight of faith to carve a crack in absolute inevitability. It is an enclave ruled by "meaning" and "choice," small, yet powerful enough to defy the eternal void.
