#Kagura Domain and the Gate — A Bridge Laid Between Two Ages

Contents

This document belongs to front. There are no new rules or new numbers here — all it does is set up the single question this issue will answer: "who walks upon the gate." For canon facts about factions, timeline, and the gate, co-02-03, co-02-06, and ex3 take precedence; this document only lays fiction atop them.

#Brief — The Two Faces of Kagura Domain

Kagura Domain (神樂藩) is, in canon, the human faction with the greatest military might against the yoma (co-02-03). Yet that name was not won by force alone. Beyond a generation ago, on the night the first abbot of Mount Hiei sealed the archfiend Enma-doji (閻魔童子), it was those who kept vigil at his side whose descendants became Kagura Domain. Blade and seal mingled in one bloodline — a "sealing lineage."

Kagura Nobutsuna (神樂信綱), the Sengoku-era lord of Kagura Domain, holds that the very act of subjugating the yoma is the legitimacy for unifying the realm. When the hand that grips the sword and the hand that knows the seal came together as one, that hand could reach for the realm however far it wished. It lacked nothing — not in force, not in cause, not in the authority a bloodline confers.

And yet by the Edo age, Kagura Domain is not master of the realm. It has withdrawn into a special domain watched over by the shogunate, into a single house keeping an old exorcists' vow (ex3, Kagura Domain in that age). Why did the mightiest force settle into the seat of a great-yoma warden instead of grasping the realm?

This issue's first answer is this — it was not a retreat but a return. The seat Kagura Domain occupies in Edo is the very seat where they were born. The hand that kept vigil on the night of the sealing. The hand that never coveted the realm and only ever warded the gate. The Kagura Domain of Edo did not lose anything; it went back to where it belonged. And the rest of this issue unfolds, in four paths, what realm might have opened had that hand not returned to its place.

#Brief — The Gate to the Spirit Realm, Three Ages

The Gate to the Spirit Realm opens when the blood of war seeps into the earth (co-02-06, on the gate's opening). That gate wears three faces across three ages.

Heian — a gate faintly opened here and there. No one knows fully where it lies, and it is not even clear whether it stands open — dim clefts in the half-light.
Sengoku — a gate flung wide by war and blood. Ceaseless fighting soaks the earth, and the gate gapes at its widest. This is the "now" upon which this issue stands.
Edo — a gate under management by administration and concealment. The shogunate could not close the gate, but it pasted paper over the seam and stamped it with an official seal. The gate has never once been closed — only erased from the records, veiled behind law, and dressed up as a matter of public order (ex3, the central thesis).

The event set at the very middle of the bridge this issue draws is precisely that transition itself — the moment the "gate flung wide" shrinks into the "gate under management." How did the widely gaping gate of Sengoku contract into the seal-stamped gate of Edo? Who gripped the handle of that contraction? Canon says the answer is Kagura Domain's sealing, the three heroes' unification of the realm, and the shogunate's system for managing the great yoma. This issue asks, "what if a different hand had gripped that handle."

And in the spirit realm, time does not flow in one direction. Past, present, and future are jumbled together in a single place, so that objects bearing the names of ages not yet come — a future blade, future armor — flow into the now of Sengoku (spirit-realm relics, co-02-06). What this means is simple. Sengoku and Edo are not separate ages; they are already joined as one body called the spirit realm. The bridge was laid from the start. We have merely not yet walked upon it.

#Commentary — The One-Line Thesis

"The bridge is already laid. The question is who walks upon it."

Canon says that Kagura Domain's sealing and the three heroes' blades walked upon this bridge. From Sekigahara to the winter and summer of Osaka, and on to Tokugawa's great peace and the shogunate's system for managing the great yoma — that is the path actually walked (ex3). This endpoint never changes in this issue.

But those could not have been the only feet to set upon the bridge. The hand gripping the mightiest force could have coveted the realm. The things beyond the gate could have walked by borrowing a hand on this side of it. A divine might sealed and asleep could have walked back out to the seat of politics. This issue raises those "feet that might have walked" as three forking IFs, and sets the path canon actually walked alongside them. None of them replaces canon. Even canon is but one step walked upon a bridge already laid (fc10, the principle — even the official history is only one path).

#Scent — Before the Gate

On Mount Hiei at night, the people of Kagura stood upon ash where the seal's brand had not yet cooled. The blood on the sword-hilts was neither man's nor that of things not-man. Before them the gate was contracting, little by little — the maw that had gaped wide narrowing to a seam fit for a single sheet of paper.

Someone asked. Now do we go forth to the realm?

The lord did not answer. He only laid his hand upon the contracting seam. Beyond that hand, four ages not yet come wavered, overlapping like shadows. In one, the blade monopolized the gate and leveled itself at the realm; in one, the thing beyond the gate donned a human guise and sat upon the throne; in one, a sun long asleep rose again and rested upon the hands of three houses. And in the last — the hand before the gate remained simply a hand before the gate.

The lord's hand fell from the seam. As if an official seal were pressed down, the gate at last locked to the thickness of a single sheet of paper.

"The bridge was already laid," the lord said quietly. "We simply had not walked it."

The wind swept away the ash, and the four shadows waited to fork from one another upon a road no one had yet walked.

#The Four Paths — Four Realms Beyond the Gate

The following documents unfold, one by one, the four feet that could have walked upon this bridge.

True history — the sealed realm. The path where the gate contracted through Kagura Domain's sealing, the three heroes' unification, and the shogunate's management system. → 02 The Sealed Realm
IF-A — if the blade covets the realm. The branch where the buke (武家) monopolizes the seal and raises a realm upon the sword's edge. → 03 If the Blade Covets the Realm
IF-B — if the yoma grasps the realm. The branch where the thing beyond the gate borrows a human hand to rule a realm of puppets. → 04 If the Yoma Grasps the Realm
IF-C — if the sun rises again. The branch where a sealed divine might returns to politics and the three houses uphold a theocratic order (神政). → 05 If the Sun Rises Again
