Major Beats

Encounter 1 — Seven Doors Under Cumae
Overview
Track the page through smoke-carved doors while false futures try to split the party.
🗺 Terrain
Forked cave hall with seven labeled doors, ankle-deep water, laurel roots, and smoke vents.
Mechanics
- Investigation challenge: 5 successes before 3 failures at DC 15 finds the real smoke trail.
- Each failure costs 5 minutes and animates a Smoke-Warden patrol.
- The Laurel-Ash Phial reveals one hidden verse and cancels one false-door consequence.
- Non-combat route: cite the correct verse to make the acolytes kneel and open Door IV.
Creature Cards
Lucius Varron of Misthaven
Roman envoy, quest giver
Motivation. He wants the final Sibylline page delivered before rival augurs declare a false destiny.
Secret. His patron already owns six forged pages and needs the real one to expose them.
Hard rule. No page may leave unread; an unopened prophecy curses its bearer with borrowed years.
Laurel-Ash Phial
Sacred focus, prophecy preservative
Appearance: Glass tear of gray ash and green sparks tied with red wool.
Handout. "Dust to dust is lazy magic; ash remembers the shape of every fire."
Enc. 1–2. Sprinkle to reveal hidden verse, granting advantage on one Investigation or Religion check.
Enc. 3. Cast into the page-fire to freeze the burn clock for 2 rounds or reveal the safe exit door.
Smoke-Warden Acolyte
Medium Creature · CR 3 · Ritual guard
AC 15 | HP 67 | Speed 30 ft.
Note. Drops a key phrase if captured or out-argued.
Attack. Censer chain +6 to hit, 11 bludgeoning plus 7 fire.
Encounter 2 — The Masked Interpretations
Overview
Bronze masks recite mutually exclusive futures while Amelia begs the party to trust the living voice.
🗺 Terrain
Round archive, hanging masks, cracked lectern, black-water channel, and a sealed page niche.
Mechanics
- Debate or fight three interpretations; Insight/Religion DC 16 identifies the one that eats the future.
- Recruit Amelia by defending her reading for one full round or giving her the laurel scrap.
- A Bronze Mask can possess a PC until splashed with channel water or beaten on a contested Charisma check.
- Correctly ordering three lines opens the niche without adding heat to the page.

Encounter 3 — The Last Page Burns Forward
Overview
Carry, read, and protect a burning prophecy while the Pyre-Voice collapses the escape route.
🗺 Terrain
Ascending lava-lit stair, three prophecy doors, falling roots, and a moon well exit.
Mechanics
- Burn clock starts at 6; at initiative 20 reduce it by 1, or by 2 after a failed group save.
- The Laurel-Ash Phial freezes the clock for 2 rounds or reveals which exit matches Amelia's verse.
- Win by reading the true future aloud at the moon well, bargaining with the Ember-Lamia, or escaping with preserved ash.
- Killing the Pyre-Voice only buys 1 round; the cave still seals unless the prophecy is resolved.
