#Scent — Things Built From Stone And Prayer

The domain's buildings have memory.

The pine at the Main Hall has seen 3 generations. They say the onmyoji first raised a Barrier beneath this tree when he was young. The shrine bell was offered by the lord's grandfather. On the kokuchi(告口), it says "Hinototori year" — the year this domain first suffered a bad harvest.

The smithy's furnace has not gone out through seventy winters. Nohachi's father inherited it that way, and Nohachi keeps it that way. The day it goes out is the day this domain ends — that is not exaggeration. It is literal.

The well is older. Records say it has been here for 300 years. Some say that is why the domain is called Kagamiyama(鏡山). A mirror-like well. A folk tale says your past is reflected if you look into it.

After the drift, these buildings began to change. The moss on the stone walls grew a little greener, and the grain in the wood grew a little deeper. The onmyoji says the Spirit Realm's energy is stimulating the buildings' "memory."

To protect these ten facilities is to protect the domain. Lose even one, and one organ in the domain's body stops.

#Facility Summary Table (Starting Point)

For quick reference.

Facility	Location	Starting State	Weekly Output	Effect If Destroyed
Main Hall	fortress	2	meeting and administration	morale -4
Shrine	northeast	2	Barrier ritual	Barrier HP -20
Smithy	western edge	2	weapon 1/week	morale -2
Clinic	village	2	healing 3 times	morale -2
Well	center	2	drinking water supply	morale -5

South Gate	south	2	defense line	invasion +3
Shelter	underground	1	final sheltering	ending change

3 facilities at initial state 1: storehouse, east gate, shelter. Recovery during Chapters 1~2 is a main objective.

#Weekly Facility Maintenance Check

Every Monday morning, check each facility's state. The GM reveals only facilities where changes occurred, not the entire list.

#Change Triggers

Special result on event d100
Combat occurs(possible zone terrain destruction)
Manpower changes(NPC death or injury)
Resource changes(supply shortage → state drop)

#State Increase Check (Recovery)

Facility recovery check:
 Condition: materials, manpower, time
 Check: 2d10 + relevant skill + material bonus >= Target Number
 Success: state +1
 Failure: materials lost, retry possible(wait one week)

Damaged → normal: Target Number 11(materials 2 gold)
Destroyed → damaged: Target Number 15(materials 5 gold + 2 weeks)
Normal → excellent: upgrade procedure(01-05)

#State Decrease Check (Neglect And Destruction)

Automatic drop conditions:

Condition	Drop
morale 3 or lower persists for 2 weeks	1 arbitrary facility 2→1
Barrier HP 15 or lower	facility-specific additional risk +1
zone exposed by combat	facility in that zone takes 2d10-12 damage
operating personnel die	facility immediately drops by 1

#Facility Interactions

The relationships between facilities are not simple. Some have required connections.

Connection	Relationship	Spillover
Main Hall ↔ Watchtower	attached relationship	if Main Hall is destroyed, Watchtower also drops by 1
Shrine ↔ Storehouse	core circulation	if Storehouse is destroyed, Barrier ritual confusion → additional Barrier HP -3
Smithy ↔ Gates	repair relationship	if Smithy is destroyed, Gates automatically lose -0.5 state each week
Clinic ↔ Farm	herb supply	if Farm production drops, weekly medicine -1
Well ↔ Shrine	purifying water	if Well is contaminated, Barrier ritual check -2
Shelter ↔ Main Hall and Shrine	underground connection	if Main Hall and Shrine fall, Shelter access is blocked

If the GM manages these chains, facility destruction gains psychological weight.

#External Trade Facilities (Auxiliary)

Not direct facilities, but involved in domain operation.

#Outsider NPC Trading Post

Location: south gate edge(inside the Barrier boundary)
Operation: some outsider NPCs(02-05 Drifted Outsiders)
Function: equipment, herbs, and information trade(weekly 1 time)
Risk: outsiders cannot be fully trusted

#Traveling Merchant

Appearance: 1~2 times/month(d100 event)
Goods: cores, specialties, rare items
Risk: some of them are Spirit Realm intelligences(02-06)

#Facilities And Campaign Progress

Facility goals by chapter.

Chapter	Main Recovery And Upgrade	Must Maintain
Chapter 1	storehouse and east gate recovery(state 1→2)	Main Hall, Shrine, Well
Chapter 2	shelter recovery + Shrine stage 1	Smithy, Farm
Chapter 3	Smithy stages 1~2 + Watchtower stage 1	Clinic, Gates
Chapter 4	Main Hall upgrade + Well stage 2	all
Chapter 5	final upgrade or sacrifice choice	Shelter, Shrine

#GM Operation Tips — Make Facilities Feel Alive

#Give Facilities Faces

Facility = the NPCs who work there. Major NPCs are already defined in 02-04 Common Folk.

Main Hall = Lord Akihisa + head maid Ine
Shrine = onmyoji Gensho + shrine maiden Sayuri
Smithy = Nohachi + Kansuke
Clinic = Yasuko
Well = wellkeeper Shobe(+residents gathered by the well)
Farm = village head Heisaku
Storehouse = storekeeper Tagoro
Watchtower = guard captain Yaeemon

#Make Output Visible

"This week, 1 yari is finished" — in head Nohachi's voice.
"Friday's rice harvest is 70 koku" — from the village head's ledger.
"All 3 patients are discharged" — physician Yasuko's report.

Make players feel the people behind the numbers.

#Stage State Drops

If state 2→1 looks like only a number, nothing happened. It needs staging.

"A new crack has opened in the east gate planks. Nohachi is driving nails in to hide it."
"There are more rats in the storehouse than last week. The storekeeper counts them at night."
"The well's bucket rope has shortened. A 30-ken rope has become 28 ken."

#Anticipation For Upgrades

Make players dream about the next upgrade. Once or twice each chapter, mention, "When this upgrade unlocks, this becomes possible."
