+# Cosmology — the Warden and the Seven
+
+The overarching theme of the Margreave. Every new piece of content sits inside
+this hidden war and must not contradict it. The canon lives in
+`content/lore/cosmology.md` and `content/lore/the-seven.md`; this file is the
+author-facing summary + the rules that keep it in tone. Read it before writing
+lore, NPCs, quests, or items.
+
+## The frame
+
+- **The Warden** (`person.the-warden`) — a genuinely good, *distant* god. Made
+  the races, loves them, wards the world against the Seven. Answers worship with
+  rare blessing and does not otherwise intervene. **Nameless by design** — no one
+  living speaks his name; never invent one. Whether he is good, absent, or dead
+  is the world's oldest argument, never settled by the narrator.
+- **The Sent** (`faction.the-sent`) — his angels. Indirect: a Sent one *asks* a
+  mortal to do a deed in his name; blessing follows the deed. Rare — most people
+  never meet one. This is the cosmic-flavored quest-giver vein.
+- **The Seven** (`faction.the-seven`) — seven demon kings + armies, the Warden's
+  enemy. Want the races dead or enslaved. Run on **blood** (`rule.blood-price`):
+  sacrifice buys their power. The roster (`content/lore/the-seven.md`): Kareth
+  (slaughter), Vael (betrayal), Morren (plague/mercy-kill), Ghaul (bondage),
+  Ishri (appetite), Nuun (madness — chief possessor), Draeth (tyranny).
+- **Possession** (`rule.possession`) — how the Seven reach mortals: mostly
+  *influence* (a hand on the scale of what a person already wants), rarely
+  outright seizing a body (Nuun's specialty). A possessed mortal is a victim; the
+  thing inside is the enemy.
+- **The two economies** — worship→blessing (`rule.the-pact`) vs
+  blood→power (`rule.blood-price`). Both express through Luck's *flavor*, never
+  numbers (see below).
+
+## The FTH-axis callings (from the races/classes spec)
+
+The two divine callings draw power from opposite sides; the rest are unaligned.
+- **Bonesetter** (Cleric, FTH) — channels the Warden; healing *is* his blessing.
+- **Bloodsworn** (Warlock, FTH) — pacted to one of the Seven; the "Pact Mark"
+  talent spends a thread of a lord's blood-price power.
+- **Hedge-Mage** (Wizard, MAG) — outsider; arcane is *studied*, serves neither.
+- Martials (Sellsword/Trapper/Barbarian) — unaligned; the war only echoes.
+Callings are code-owned state — reference them in prose, never author a "class"
+entity. (A Bloodsworn's patron choice and any Luck effect are M4/M5, not content.)
+
+## Authoring rules — keep it in tone
+
+1. **Distant.** The cosmology is the hidden engine under local grime, not the
+   surface text. A corrupt mayor can just be a corrupt mayor.
+2. **Through people.** Demons work by influence; possession is rare and quiet.
+   No manifesting monsters in the square, no preaching narrator, god unconfirmed.
+3. **Not epic.** Keep the gritty, indifferent register (see `tone.md`). Cosmic
+   stakes stay implied, argued-over, never announced.
+4. **Blessing/curse ↔ Luck.** Express which side has hold of someone through
+   Luck's *flavor* ("fortune spits on you") — never a number, never something the
+   player can calculate. A cursed item (+STR / −LCK) is a small bargain with the
+   Seven.
+5. **Victims are gated secrets.** WHO is possessed, WHICH road is bled, WHICH
+   shrine is a front — author as per-town `rumor`/`fact`/`secret` with disposition
+   gates, not stated in the open. The frame gives you hooks; you place the wounds.

+## The cosmic backdrop (the Warden and the Seven)
+
+The world sits inside a hidden war — a distant good god and seven demon kings
+(see `references/cosmology.md`). It colors tone but must never break the world's
+indifference:
+
+- The cosmology is the **hidden engine**, not the surface text. Day-to-day the
+  world is still taxes, mud, and bad men; the war is what's *underneath* them.
+- Demons work **through people** — influence, rarely possession. Write the
+  wreckage and the person going wrong, not a monster in the square. The narrator
+  never confirms the god, never preaches, never goes epic.
+- Which side has hold of someone reads through **Luck's flavor, never a number**
+  (a blessing is a run of fortune; a curse is the trap door opening under you).
+- The good/evil is real but **argued-over** — most folk dispute whether any of it
+  is true. Certainty is the enemy of this tone as much as of §7's Luck.
