Players 6 × Level 8 · 3–3.5 hrs · 3 encounters
Key Ally Half-Tamed Pegasus (recruit Enc. Enc. 1 or Enc. 2) · Maguffin: Humble Bridle

Description

Melanippe of the Bridle Shrine hooks the party. Maguffin Humble Bridle pays off in the finale against Chimera of the Bragging Crag. Recruit Half-Tamed Pegasus along the way.

Ride a half-tamed Pegasus to drive off a Chimera without claiming the kill for pride.

"A moon-silver bridle tag etched with 'borrowed wings return heavier than stolen ones.'"— Given at Athena's roadside shrine

Major Beats

  • Pegasus watches from a ridge and judges every hand movement.
  • Bellerophon smiles like a hero one compliment away from ruin.
  • The Chimera's three heads argue over which rider smells proudest.
  • The best victory is loud in the sky and quiet at the feast.

Encounter 1 — The Bridle Shrine

Enc. 1 - Recruitment · ~50 min

Overview

Earn the shrine's blessing, find Pegasus's tracks, and learn why this bargain punishes vanity.

🗺 Terrain

Olive grove shrine, dry streambed, thorn snare, high meadow, and a broken boast-stone.

Mechanics

  • Recruit Pegasus with 4 successes before 2 failures using Animal Handling, Religion, Acrobatics, or Persuasion.
  • Drawn weapons or trophy talk impose disadvantage until someone makes a sincere apology.
  • The Humble Bridle may be offered, not forced; forcing it starts a chase instead of recruitment.
  • Cultists spy from the rocks and flee if exposed without bloodshed.

Creature Cards

👤

Melanippe of the Bridle Shrine

Priestess of Athena, keeper of a dangerous favor

Motivation. Make sure the Chimera is stopped by disciplined heroes rather than another glorious fool.

Secret. Bellerophon has already been warned that claiming the kill will cost Pegasus's trust.

Hard rule. She refuses to bless any plan that treats Pegasus as loot or a god-given siege engine.

Humble Bridle

Divine-adjacent tack, pact of restraint

Appearance: Plain leather with a moonlit bit that grows lighter when thanked.

Handout. "Hold with open hands. Ask before ascent. Return before applause."

Enc. 1–2. Grants advantage on one Animal Handling, Acrobatics, or Persuasion check involving Pegasus.

Enc. 3. If a rider refuses the killing blow while holding the bridle, Pegasus can force the Chimera to retreat.

Aid. Acts on party initiative when recruited; prefers nonlethal when asked.

Strike. Hooves +8 to hit, 13 bludgeoning; wing burst lets one rider move 40 feet without provoking.

Encounter 2 — Lessons Above Lycia

Enc. 2 - Aerial skill challenge · ~55 min

Overview

Practice shared riding, rescue shepherds, and map the Chimera's thermals before the final ascent.

🗺 Terrain

Switchback cliffs, shepherd ledges, hot updraft vents, and cloud gaps over a ravine.

Mechanics

  • Each aerial stunt needs DC 15 Acrobatics, Athletics, Animal Handling, or Arcana to use wind safely.
  • Failure separates a rider, costs Pegasus 10 HP, or lets an Ash-Mane Lion threaten civilians.
  • Saving shepherds gives the route to the Bragging Crag and a safe landing zone in Enc. 3.
  • Bellerophon shadows the party; humbling him now prevents a dangerous boast in the finale.

Encounter 3 — The Bragging Crag

Enc. 3 - Hard boss hunt · ~85 min

Overview

Battle the Chimera amid volcanic updrafts while denying it the boast that feeds its legend.

🗺 Terrain

Basalt spire, three thermal vents, broken hero statues, cloud shelf, and a smoking goat-path.

Mechanics

  • At initiative 20, choose a vent: lift 30 feet, fire burst 14 damage, or smoke lightly obscures a lane.
  • Mounted PCs can trade an action to steady another rider and prevent a fall.
  • Maguffin payoff: refuse the killing blow with the Humble Bridle to let Pegasus drive the Chimera off.
  • If someone boasts ownership of the kill, the Chimera heals 25 HP and Pegasus demands a DC 17 apology check.
