📜 Session Summary

Players 6 × Level 8 · 3–3.5 hrs · 3 encounters
Key Ally Myrto with the Blue Lantern (recruit Enc. Enc. 1 or Enc. 2) · Maguffin: Balanced Obol Ledger

Description

Charon, Overworked Boatman hooks the party. Maguffin Balanced Obol Ledger pays off in the finale against The Fare-Thief in the Wake. Recruit Myrto with the Blue Lantern along the way.

Hold Charon's barge steady while too many living souls try to buy a one-way crossing.

"A damp manifest with too many living names and only one column marked 'return fare.'"— Stamped by Charon without looking up

Major Beats

  • A living mother offers Charon every coin she has and the name of her last enemy.
  • The dead mutter that the living always think grief is a ticket.
  • The barge tilts when someone lies about who belongs aboard.
  • A stolen name drips from the boss's hook like black ink.

Encounter 1 — The Queue That Should Not Breathe

Enc. 1 - Social triage · ~50 min

Overview

Sort the living from the dead, spot forged fares, and keep panic from rushing the gangplank.

🗺 Terrain

Styx dock, rope lanes, obol booth, shade benches, and black water below loose planks.

Mechanics

  • Run triage as 5 successes before 3 failures using Insight, Persuasion, Religion, Medicine, or Intimidation.
  • Each failure adds 1 to the Overfull clock; at 3, passengers surge onto the barge.
  • The Balanced Ledger reveals one forged fare or rightful return with each strong clue.
  • Recruit Myrto by recovering her name-token from a living petitioner using it as false fare.

Creature Cards

👤

Charon, Overworked Boatman

Unique undead ferryman, neutral keeper of passage

Motivation. Keep the crossing lawful, paid, and afloat despite living petitioners forcing their way aboard.

Secret. Someone forged return fares with ink made from stolen memories.

Hard rule. He will not abandon the dead, waive the oldest laws, or let the party kill passengers to simplify the load.

Balanced Obol Ledger

Underworld manifest, lawful counterweight

Appearance: Black reed-paper pages sewn with coin-bright thread and damp thumbprints.

Handout. "One fare, one name, one shore. Cross out a lie before it learns to row."

Enc. 1–2. Identifies forged fares, calms one passenger group, or reveals who belongs on the return shore.

Enc. 3. Balanced on the prow, it stabilizes the barge and exposes the undead smuggler boss for 1 round.

Encounter 2 — Midstream Weight

Enc. 2 - Escort skill challenge · ~60 min

Overview

Keep Charon's barge balanced while living souls bargain, dead souls object, and the Styx starts listening.

🗺 Terrain

Long black ferry, pole lanes, passenger benches, coin brazier, and fog banks hiding swimmers.

Mechanics

  • Balance clock starts at 0; failures move it toward capsize, successes move passengers to lawful places.
  • Useful checks include Athletics at the pole, Persuasion at the benches, Religion with rites, and Perception in fog.
  • Charon rows and judges; he helps clear one lawful order but never becomes a damage solution.
  • Coin-Drowned Dead board if forged fares are burned without naming the thief first.

Encounter 3 — Too Many Names in the Wake

Enc. 3 - Hard holdout · ~85 min

Overview

Fight the undead smuggler and river horrors while holding the ferry steady and protecting passengers.

🗺 Terrain

Tilting ferry deck, two side rails, prow ledger stand, stern bell, and grasping black water.

Mechanics

  • At initiative 20, roll a ferry event: list, passenger fall, fog wall, or Styx surge.
  • A PC can spend an action to stabilize the barge, rescue a passenger, or command a lawful seating shift.
  • Maguffin payoff: place the Balanced Ledger on the prow to reveal the Fare-Thief and reset the Balance clock once.
  • Charon cannot be killed for victory; if attacked, he stops rowing and the river becomes the real disaster.
