he Fracturing (Cheonha Bunhae)

The catastrophe that broke the Celestial Pillars, collapsed the Great Balance, and tore the boundary between worlds, releasing Maggi into Haneul-ttang.

What Happened

An order of scholar-sorcerers called the Cheonmugwan (천무관, Celestial Martial Court) tried to tap the Celestial Pillars directly, hoping to ascend to the level of the Five Celestial Spirits. Their ritual, the Cheonmyeong Uisik (천명 의식, Rite of Heaven’s Mandate), failed catastrophically. Three of the five Cheonseokju (천석주) shattered and the remaining two were badly cracked. The Gyunhyeong (균형), the Great Balance the pillars held between the spirit and mortal worlds, collapsed, and the boundary between those worlds tore open. This event is the Cheonha Bunhae (천하 분해), the Fracturing of the Heavens.

Consequences

With the pillars no longer filtering and anchoring Giun (기운), unfiltered Giun seeped out as Maggi (막기, Obstructed Energy), a corrupting force that warps living things. Foxes, wolves, bears, and tigers grow monstrous and aggressive. Rats and vermin absorb Maggi quickly and are the first sign of corruption. Deep places near the broken pillars, caves, mines, and underground ruins, pool the thickest Maggi and hold the worst monsters.

The torn boundary stopped the dead from passing on. Before the Fracturing the pillars kept the boundary intact, and a spirit passed through when its owner died. Afterward they had nowhere to go and began piling up in the mortal world, especially those who died violently, suddenly, or with things left unfinished. They became skeletons and ghosts. The Han (한), the unresolved grief that anchors a soul, that once might have been too minor to trap anyone is now enough to hold the dead in place. Those fully corrupted by Maggi never truly die; they remain in its grasp as tools of the corruptive force, their bodies turned against their minds, which is why such creatures return after they are struck down.

Canonical source. The dead stranded by the broken boundary is defined here. It is also restated in Han (Unresolved Grief), Maggi, Danja Manuscript (Deep Lore). Keep them in sync.

Maggi as a Meta-Emotional Force

Maggi is not strictly geographic. As the opposite of Giun, it behaves as a meta-emotional force, gathering more thickly in places marked by grief or suffering. Graveyards and dangerous roads where people have died draw it. This gives killing a corrupted creature, a ghost, or a Maggi-warped beast the weight of mercy rather than simple extermination. The corrupted are suffering, not evil. The true evil sits at the end of the chain, in whatever was ultimately created at the core of the Cheonmugwan ritual.

Aftermath

The great courts fell. The Cheonmugwan were destroyed or scattered and are now reviled, and only scattered cities survived into the Age of Endurance. The survivors of the order, who stood at the very center of the Fracturing and were washed over by Maggi at its purest, suffer the agony of immortality. Their bodies are deeply disfigured, many missing senses (eyes ruined, ears burned over, mouths sealed shut), their skin crawling with black lines of corruption. Those survivors split into factions divided over whether the ritual was a failure to repent for or a first step to finish.

The Transcendence path open to players today carries an uncomfortable echo of the Fracturing. Where the Cheonmugwan tried to take power from the pillars by force, a transcendent player takes a shard of a broken pillar into themselves to become an avatar of a spirit, and not everyone sees the difference as clean.
