#Conventions — This Expansion's Own Conventions

Contents

#Identity

It directly inherits the 1st expansion's conventions (file names · § Scent/Law structure · dice restrictions, etc.) while specifying additional conventions unique to this expansion.

#Design Goals

#Inherited (Same As the 1st Expansion)

• File name: XX-YY-descriptive-name.md
• § Scent (香) → § Law (法) structure
• Dice: 2d10 · d100 · d10 only. Other polyhedra are forbidden.
• Time unit: Round (間合). Separate round/turn vocabulary forbidden.
• Title: Korean + Kanji/Romaji parenthetical.

#This Expansion's New Conventions

• Selectable-module notation — an optional rule states clearly at the head of the document that it is a selectable module.
• Replacement-scope notation — specify early in the document which part of the core it changes.
• Stacking notation — write so it is immediately clear whether it can be used together with other rules or is a standalone replacement.

#School-Type Notation (New In This Expansion)

• 4 school types: famous school · Secret Transmission · Self-Taught Style · foreign style (new)
• Note the type at the top of each school document.
• Assign at least 3 schools per skill.

#Narrative Flags

• Play type — write so the operation that the given school, feat, or module recommends is graspable right away at the top of the document.
• Cultural origin — for foreign-style schools, clearly note the source and cultural origin at the top of the body.

#§ Era / Cultural-Sphere Disclosure Principle (★ This Expansion's Core Convention)

This expansion takes the Japanese Sengoku era (戦国時代, 1467-1603) + yoma setting as its basic support, but actively permits the introduction of foreign-style, era-transcending schools and divine items. Era-consistency verification follows these principles:

#a. An Era Violation Is Not a Disqualification — Disclosure Alone Suffices

• Even if a school, person, or tool is from after the Sengoku era, it can be used in this expansion as long as you disclose its source, era, and cultural sphere.
• Items outside the disclosed era are run, at GM discretion, in one of the following ways:

1. One who crossed the eras: descent of a heroic spirit(英靈) · time drift · reincarnation.
2. A campaign of another era/culture: a GM-homebrew era campaign such as the Bakumatsu, Qing, modern, or ancient.
3. Alternate history: a fictional trend that arrived early in the Sengoku era.

#b. Notation Standard

Disclose the following information at the top of each school, divine-item, and person entry:

**Source**: [school/text/lore origin]
**Era**: [time of establishment or activity]
**Cultural sphere**: [country · region · people]

Examples:

• Tennen Rishin-ryu: Source — Bakumatsu Shinsengumi / Era — established 1789, active in the 1860s / Cultural sphere — Japan, late Edo · Bakumatsu
• Keshik: Source — Genghis Khan's bodyguard / Era — 13th-century Mongol Empire / Cultural sphere — Mongolia
• Aikido: Source — established by Ueshiba Morihei / Era — 20th-century Japan / Cultural sphere — modern Japan

#c. Historical Errors Are Corrected Precisely

Era disclosure is free, but errors of historical fact are corrected precisely:

• Classifying Aikido as "modern Korean" ✗ (Aikido is Japanese)
• Placing Shaka Zulu in the 16th century ✗ (1787-1828, 19th century)
• "Korean xiakke" ✗ ("xiakke" is Chinese; the Korean terms are Geomgye · Walja)
• "Bajiquan established in the 16th century" ✗ (established mid-Qing; introduction after noting "Bajiquan (established in the Qing era)" is OK)

#d. Campaign Tone Guide

The GM chooses one of the following at Session 0:

• Pure Sengoku era: when using schools outside the disclosed era, a heroic-spirit · reincarnation · drift narrative is required.
• Era-transcending Eastern wuxia: era disclosure is used only as Scent(香), and mechanisms are introduced freely.
• A campaign of another era: Bakumatsu, Qing, modern, etc. — use only that era's schools, selectively.

All of this expansion's schools are designed to be able to accommodate all 4 of the tones above.

#Link-Prefix Convention

#Reference Documents

#§ Homebrew-Content Convention (When the GM Homebrews)

When the GM adds homebrew content (schools, squads, masterworks, etc.), follow this convention:

1. Follow the file name rule (XX-YY-name.md)
2. Keep the § Scent / § Law structure
3. Disclose source · era · cultural sphere
4. Pick 1 of the 4 school types
5. Present play type · access conditions so they can be seen at a glance
6. Balance to core ±1 power
7. Do not modify the core original

For details, see 21-05 Homebrew Guide.
