#Out of Scope — Declaration Excluding Myth-Tier Yoma

Contents

Canon — fc01 scope declaration. This supplement deliberately does not cover the categories of beings below. This is a design principle, and future fcNN will carry it on.

#Declaration

Myth-tier yoma (神話級妖魔) are not targets for stat-out in this supplement.

  • Each of them is a being that can be handled only when a stat block + scenario design + environmental rules form a single whole.
  • An attempt to summarize them in a single data card betrays their essence.
  • They must be handled not by "how strong they are" but by "what story they are a part of."

#Target List

#Japanese Myth

  • Yamata no Orochi (八岐大蛇) — a great serpent with eight heads · eight tails. A being slain by Susanoo. Susanoo's heroic narrative itself is the scenario.
  • Nue (鵺) — a monster combining several animals. The tale of Minamoto no Yorimasa.
  • Ushioni (牛鬼) — a giant ox-headed monster of the seashore.

#Norse Myth

  • Jormungandr (Jörmungandr) — a colossal sea serpent encircling the world. Kills Thor at Ragnarok.
  • Fenrir (Fenrir) — a giant wolf that kills Odin.
  • Nidhoggr (Níðhöggr) — a dragon that gnaws at the roots of Yggdrasil.

#Mesopotamia · Judaism · Islam

  • Tiamat (Tiamat) — the primordial sea goddess · dragon of Babylonia.
  • Leviathan (Leviathan) — the giant sea beast of the Old Testament.
  • Behemoth (Behemoth) — the giant land beast of the Old Testament.

#Greece

  • Typhon (Τυφών) — a typhoon giant who fought Zeus.
  • Python (Πύθων) — a giant serpent slain by Apollo.
  • Hydra · Cerberus — can be classified as "myth-tier" depending on size · narrative.

#East (China · India)

  • Yoryong (the highest of the 四海龍王 line) — a sea dragon king.
  • Bahamut (Indian · Persian lore) — a giant fish that bears the earth.

#Lovecraft

  • Hastur · Yog-Sothoth · Nyarlathotep — Outer Gods other than Cthulhu.
  • (Only Cthulhu is included in this supplement. Other Outer Gods are excluded.)

#Reasons for Exclusion (Canon)

#Reason 1 — They cannot be handled by data alone

Take Yamata no Orochi as an example:

  • It is not a simple combat opponent. The conditions for its defeat are woven into a narrative structure of eight casks of sake · the peril of Princess Kushinadahime · Susanoo's intervention.
  • Giving "the great serpent's stat block" is meaningless. It is not even an opponent a non-Susanoo PC can defeat by stats.
  • If they are statted out, "how to win" is solved, but "why this story matters" is not.

#Reason 2 — They cannot be "the protagonist of a single session"

  • A myth-tier yoma is the climax of a campaign or the campaign itself. Dispose of it as the encounter of a single session, and the scale of the story collapses.
  • To handle them requires several sessions' worth of advance preparation · foreshadowing · environmental rules.

#Reason 3 — A single Divine Authority is insufficient for the scale

  • Shinseiki's 5-grade system focuses on "what is certain within a domain." A myth-tier yoma is a being on the scale of changing the world itself, beyond any domain.
  • Cramming this scale into 5 grades would require an expansion like "Divinity 10." At that moment the system collapses.

#Then How Are They Handled

#co's Existing Rules

  • If co already handles some myth-tier yoma, those rules take priority.
  • This supplement neither extends nor modifies them.

#Future fcNN Scenario Focus

Among the fc releases after this supplement (fc01 Shinseiki), the following are planned for separate publication as scenario packages that handle myth-tier yoma:

  • Candidate 1 — "Chronicle of the Great Serpent's Battle (大蛇鬪記)" — a recreation · variation of the slaying of Yamata no Orochi.
  • Candidate 2 — "Tale of the End (終末譚)" — Norse end-times narratives such as Ragnarok · Jormungandr.
  • Candidate 3 — "The Slumber of the Deep Sea (深海の眠り)" — encounters with Outer Gods other than the Cthulhu line.

Each of these fcNN will focus entirely on a single myth-tier yoma and provide session operation · environmental rules · NPCs · developments as one set.

Caution: the candidate titles · plans above are not finalized. This document only presents the direction of "how to fill in what was left out of Shinseiki."

#Distinguishing from Beings That Look Similar

#Myth-Tier Yoma vs Great God

  • Great God: a being that has a domain and has limits. Can be statted. (e.g., Susanoo, Okuninushi)
  • Myth-Tier Yoma: a "narrative calamity" not bounded by a domain. Cannot be statted. (e.g., Yamata no Orochi)

#Myth-Tier Yoma vs High-Grade Yoma

  • The strong yoma handled in co (e.g., large oni · high-grade tsukumogami) are still handled as data. These are not myth-tier.
  • A myth-tier yoma is a single being with a famous unique name · unique narrative.

#Myth-Tier Yoma vs Imperial God

  • Imperial Gods (Amaterasu · Izanagi · Izanami) are large in narrative scale, but fit within the 5 grades of Shinseiki, because their domains are clear.
  • A myth-tier yoma, even at the same narrative scale, is the event itself rather than a domain, and so lies outside the system.

#In One Sentence

"What cannot fit in a single stat block is not put in. The great serpent is not data but a night."
