The Isle of Stonegaze
The party sails to the Isle of Stonegaze aboard the trireme Ariadne's Thread , surviving a midvoyage attack by harpies and corrupted sea creatures. On the island, they cross a cursed saltmarsh, recruit allies, and scavenge tools before the final descent — before descending into the cave lair of Euryale, an ancient gorgon who guards the Eye and rules through fear and petrification.

Description
The party sails to the Isle of Stonegaze aboard the trireme Ariadne's Thread, surviving a midvoyage attack by harpies and corrupted sea creatures. On the island, they cross a cursed saltmarsh, recruit allies, and scavenge tools before the final descent — before descending into the cave lair of Euryale, an ancient gorgon who guards the Eye and rules through fear and petrification.
Handout to one party member at the tavern. Written in cramped archaic script on aged papyrus. The payoff is in Encounter 3: a still reflecting pool in Euryale's cave can be used to turn her Petrifying Gaze back on herself. (22 words)
DM Note: Don't explain the scroll. Let players puzzle it out. The still pool is prominently described when the party enters the cave. If players are stuck, Old Lysander, Priest of Apollo can confirm its meaning if the scroll is shown to him (DC 13 Insight to notice he reacts).

Major Beats
- Tavern meeting — quest briefing, scroll handoff, party hired
- 3-day voyage (DM may add minor sea roleplaying)
- Encounter 1: Harpy & Corrupted Merfolk attack on the trireme — outcome determines Long vs. Short Rest
- Trireme beaches; crew stays with the ship
- Party discovers Pyrrha and Old Lysander, Priest of Apollo hiding near the shore — roleplay and scroll clues
- Encounter 2: Mireweed Marsh — hostile lizardfolk patrol; recruit Maren, the Marsh-keeper for fire support in the final fight
- Party passes through the temple ruins beyond the marsh — scavenges the Polished Bronze Mirror, Blindfold of Apollo (from Lysander), and other tools (no combat)
- Party descends into the cave; the scroll becomes relevant
- Encounter 3: Cave boss fight — Lamias, Medusa Sentinel, and Euryale herself (enters round 3)
- Retrieve the Eye of Medusa; return to Theron (optional: moral choice / epilogue hook)
Encounter 1 — "Harpies Over the Ariadne's Thread"
Overview
A flight of Harpy descend on the trireme, targeting the sails and rigging while their luring song disrupts the crew. Simultaneously, Corrupted Merfolk board from both sides — drawn by the harpies' call, but not inherently evil. They can be freed from the compulsion and potentially recruited.
Creatures
- 4× Harpy
- 5× Corrupted Merfolk
🗺 Terrain & Features
Trireme Deck / Open Sea — 80 ft × 25 ft (deck) + sea surrounds
Mechanics
- Primary Goal: Protect the sails before they are destroyed
- The ship has 3 mast rope / sail sections, each with AC 11, HP 15. Harpies target sails over party members unless a PC is in melee reach
- If all 3 sail sections are destroyed, the ship cannot sail — party must row to shore and only earns a Short Rest before Encounter 2
- If at least 1 sail section survives, the ship is seaworthy — party earns a Long Rest aboard before landing
- Luring Song: Harpies target crew members first (not PCs unless no other targets). Charmed crew become obstacles on deck, blocking movement. A PC can spend their action to snap a crew member out of it (DC 12 CHA/Persuasion, or DC 12 STR to physically restrain/drag them)
- Freeing a Merfolk (Action): A PC adjacent to a Corrupted Merfolk can attempt DC 15 Arcana, Insight, or Religion to break the harpy's hold. Success: merfolk becomes friendly and fights for the party. Freed merfolk can be recruited (DC 14 Persuasion) to guard the ship during Encounters 2 & 3
- Captain Kleon, Captain of the Ariadne's Thread acts as helper NPC — on initiative count 5, he attacks (spear +4, 1d6+1) or attempts to lash a damaged rope (Athletics DC 12, restores 10 HP to one sail section)
- Overboard: Any creature knocked off the ship must use their full movement to climb back (Athletics DC 13). Merfolk knocked off retreat rather than re-board
| Avg. Level | Enemy Adjustments | Rest Outcome |
|---|---|---|
| Lvl 4 | 2 Harpies, 3 Corrupted Merfolk. Sail HP 10 each. Luring Song DC 9. Harpies don't target sails until round 3. | Long rest if any 2 sails survive. Short rest if all destroyed. |
| Lvl 6 | 3 Harpies, 4 Corrupted Merfolk. Sail HP 12 each. Standard Luring Song DC 11. | Long rest if at least 1 sail survives. |
| Lvl 8 ✦ | Intended balance. 4 Harpies, 5 Corrupted Merfolk. Full mechanics as written. | Long rest if at least 1 sail survives. |
| Lvl 10 | 4 Harpies + 1 Harpy Matriarch (Harpy stats, +2 all attack/saves, HP 60, fly 60 ft., Luring Song DC 13, song range 500 ft.). 6 Corrupted Merfolk. Wave 2: 3 additional merfolk board on round 4. | Long rest only if 2+ sails survive. |

Encounter 2 — "Mireweed Marsh"
Overview
After meeting Pyrrha and Old Lysander, Priest of Apollo on the rocky shore, the party must cross a salt-choked marsh that chokes the inland approach to the temple. A hostile Lizardfolk Warrior patrol — driven from their nesting grounds by Euryale's spreading curse — attacks on sight. Maren, the Marsh-keeper, a druid hermit sheltering in the crossfire, can be recruited after the fight.
Creatures
- 4× Lizardfolk Warrior
- 1× Lizardfolk Shaman
- 1× Maren, the Marsh-keeper
🗺 Terrain & Features
Boggy Marshland / Ruined Hut — 100 ft × 80 ft (marsh + channel)
Mechanics
- Maren, the Marsh-keeper is not immediately recognized as non-hostile — DC 12 Insight or Perception reveals she is cowering behind her ruined hut, shouting that the lizardfolk attacked her unprovoked. If no check is made, she shouts this herself on round 2
- If a PC moves adjacent to Maren before combat ends, she can use her reaction to cast Fog Cloud centered on the Shaman, breaking concentration — a strong coordination moment
- After combat — Recruit Maren: DC 13 Persuasion (appeal to the threat Euryale poses to the marsh). DC 10 Nature or Arcana to recognize her as a druid grants advantage on Persuasion. Showing Old Lysander, Priest of Apollo's scroll reference to "the marsh woman" (if party mentions it) drops DC to 8. Auto-success if a PC sincerely offers to protect the marsh after the quest
- DC 12 Perception (approaching marsh): Party notices bog patches and the log bridge before the lizardfolk spot them — advantage on initiative if they plan an ambush
- Recruited Maren joins Encounter 3 on initiative 8 with spellcasting support (see creature card)
- Map Features: 4× shallow bog patches (15×15 ft., difficult terrain for non-lizardfolk); 3× mangrove trees (half cover, DC 12 Athletics to climb); 1× log bridge over a deep channel (DC 12 Acrobatics; fall costs 15 ft. movement to exit); Maren's ruined hut (three-quarter cover)
- Swamp Stride: Lizardfolk Warriors and Shaman ignore difficult terrain in shallow water (≤3 ft.) and use bog patches for flanking angles
- Shaman Tactics: Opens with Spike Growth on the log bridge or main approach, then switches to Call Lightning from range. Retreats into water if threatened in melee
- Warrior Tactics: Multiattack with bite and javelin; use Clamping Jaws reaction on opportunity attacks (grapple on hit, DC 13 STR escape)
- Atmosphere: Cloudy, dim light; no darkness penalties but visibility feels oppressive — the marsh is too quiet for a wetland full of life
- Harder: Shaman pre-casts Spike Growth before initiative. Warriors use the bridge as a choke point. Add 1 Warrior
- Easier: One Warrior retreats into deep water below half HP. Shaman has 2nd-level spells only (no Call Lightning)
| Clay flasks of rendered fat mixed with marsh-pitch and a striker-wick. Shatters on impact in sticky flame. |
| Action: Throw up to 20 ft. (+PB Dex to hit). On hit: 2d6 fire damage. |
| Bonus Action: Throw up to 10 ft. On hit: 2d6 fire; on miss: 1d6 fire splash anyway. |
| Provided by: Maren, the Marsh-keeper on successful recruitment. |
| Maren knows Euryale's serpent-crowned guardians are vulnerable to sustained flame — radiant and fire damage prevent undead reformation in the ruins ahead, and fire breaks lamia concentration reliably. |
| Encounter 3 benefit: Maren opens with Flaming Sphere (2d6 fire/turn) and can cast Heat Metal on armored foes. Her fire coverage gives the party a reliable tool against Euryale's minions. |
| Provided by: Maren, the Marsh-keeper when recruited; she volunteers this if the party mentions the temple or the cave. |
| Avg. Level | Adjustments |
|---|---|
| Lvl 4 | 3 Lizardfolk Warriors, 1 Shaman (HP 38, 2nd-level spells only). No pre-cast Spike Growth. Maren helps in combat if approached (Fog Cloud only). |
| Lvl 6 | 4 Warriors, 1 Shaman (standard spells). Maren does not act until recruited post-combat. |
| Lvl 8 ✦ | Intended balance. 4 Warriors, 1 Shaman. Full mechanics as written. Maren recruitment grants Fire Flasks and Enc. 3 spell support. |
| Lvl 10 | 5 Warriors, 1 Shaman (4th-level slot: wall of fire). Shaman pre-casts Spike Growth before initiative. Warriors hold the bridge as a kill zone. |

Encounter 3 — "The Cave of Euryale" (Boss)
Overview
The party descends into a cave lair lit by green-tinged braziers. Dozens of petrified humanoids stand like statues throughout — previous adventurers, sailors, and pilgrims. A still reflecting pool glows faintly in the center of the cave floor (the scroll's payoff). Lamia and a Medusa Sentinel guard the antechamber. After round 3, Euryale, the Stone Queen — BOSS emerges from the inner chamber. Optional ally: Maren, the Marsh-keeper (if recruited in Encounter 2).
Creatures
- 2× Lamia
- 1× Medusa Sentinel
- 1× Euryale, the Stone Queen — BOSS
- 0–1× Maren, the Marsh-keeper
🗺 Terrain & Features
Underground Cave Shrine — 90 ft × 70 ft (irregular) + 30 ft inner chamber
Mechanics
- The Still Pool (Environmental — Scroll Payoff):
- ◇ Occupies a 15 ft. × 10 ft. area in the center of the cave, glowing faintly with aquatic light
- ◇ Creatures can use it to observe others via reflection — saving throws against Petrifying Gaze made this way have advantage
- ◇ Core mechanic: If Euryale (or any medusa) is within 30 ft. of the pool AND in line of sight of it, she must make a DC 17 CON save against her own Petrifying Gaze at the start of her turn. Fail: restrained. Second consecutive fail: fully petrified. Euryale is immune to the petrified condition normally — the pool overrides this via her own curse
- ◇ Maneuvering Euryale: She is aware of the danger and avoids the pool using Legendary Move. Forcing her toward it requires DC 15 Deception/Persuasion, or using the Polished Bronze Mirror to angle her gaze (DC 14 Sleight of Hand as bonus action)
- Petrified Statues:
- ◇ 8–10 statues throughout the cave provide half cover (AC 13, HP 20 each)
- ◇ If shattered (0 HP), rubble creates 5 ft. radius difficult terrain; creatures in the area make DC 12 DEX save or take 2d6 bludgeoning damage
- ◇ Lamias may deliberately shatter statues near the party
- Euryale's Entrance (Round 3): On initiative count 20 of round 3, she enters from the far end. She spends her first turn observing (only uses Serpent Strike — no Petrifying Gaze yet). This gives scroll-holders one round to react and prepare. She then activates full Petrifying Gaze from round 4 onward
- Lamia Tactics: Prioritize Intoxicating Touch on concentrating spellcasters. Use Suggestion (DC 13 WIS) to force PCs to move away from the pool or drop weapons. Avoid the pool themselves
- Medusa Sentinel Tactics: Stays at range, uses Petrifying Gaze passively (aura), only engages melee if cornered
- Maren (if recruited): Acts on initiative 8. Opens with Flaming Sphere (2d6 fire/turn) on lamias or Euryale; uses Heat Metal on armored foes; Cure Wounds on downed PCs. Her fire damage also disrupts lamia concentration
- Lair Actions (Initiative 20, active from round 3):
- ◇ Serpent Surge: Creatures within 5 ft. of a wall make DC 14 DEX save or take 2d6 piercing from animated stone carvings
- ◇ Stone Dust Cloud: 20 ft. radius centered on Euryale — lightly obscured until start of her next turn
- ◇ Cave Tremor: One 10 ft. × 10 ft. area becomes difficult terrain for the rest of the encounter
- The Eye of Medusa: Dark gem in a golden amulet setting. Glows faintly purple. Powers unclear until Theron evaluates it — possible epilogue hook about his true intentions
| Avg. Level | Enemy Adjustments | Boss Stats & Entry |
|---|---|---|
| Lvl 4 | 2 Lamias only (no Medusa Sentinel). Pool mechanic heavily telegraphed — Lysander explains it directly if shown the scroll. No lair actions. | HP 100, no legendary actions. Gaze DC 13. Enters round 4. |
| Lvl 6 | 2 Lamias, 1 Medusa Sentinel. Lysander hints at the pool. 1 lair action per round (DM's choice). | HP 140, 1 legendary action/round. Gaze DC 15. Enters round 3. |
| Lvl 8 ✦ | Intended balance. 1 Lamia + 1 Medusa Sentinel. Pool mechanic hinted by scroll only. Full lair actions from round 3. | Full stat block. Enters round 3. |
| Lvl 10 | 3 Lamias + 2 Medusa Sentinels. Pool surface is murky until a PC spends an action to clear it (Athletics or Investigation DC 14). Shattered petrified statues release toxic dust (5 ft. radius, DC 13 CON or poisoned). | HP 220, +1 legendary action (4 total). Add: Stone Wrath (3 actions) — 20 ft. cone, DC 17 DEX save, 4d8 bludgeoning on fail. Enters round 2. |

NPC Cards
Theron of Corinth
NPC · Questgiver · Neutral (suspected)
Appearance: A lean man in his 50s. Sun-creased skin, ink-stained fingers, watchful grey eyes. Dresses like a merchant; carries himself like a scholar who has seen too much.
Motivation (Surface): Claims to want the Eye of Medusa for academic study — it is said to reveal hidden truths and pierce illusions.
True Motivation (DM Only): His daughter Callista was petrified on the island during an expedition he funded years ago. He believes the Eye can restore her. He is not forthcoming about this, or about the true danger he is sending the party into.
Personality: Careful. Precise. Charming in a calculating way. Deflects direct questions with questions. Grows visibly tense if asked about the island's history or past expeditions.
DC 14 Insight: He knows more than he's saying about the island's dangers.
DC 16 Persuasion / DC 13 Intimidation: He admits a "personal connection" but not the full truth.
DC 18 Investigation (his notes / satchel): A sketch of a young woman and a name: Callista.
Kleon, Captain of the Ariadne's Thread
NPC · Trireme Captain · Lawful Neutral
Appearance: Barrel-chested, salt-and-pepper beard, scar across his left forearm from an anchor chain. Permanently squinting from years at sea.
Personality: Straight-talking and efficient. Does not traffic in fear or drama. Respects competence above all. If the ship is in danger, he says so plainly and acts.
Role in Encounter 1: Helper NPC. On initiative count 5 each round, he can make one attack or attempt to repair a sail section (Athletics DC 12 — restores 10 HP to one section).
Combat Stats (if needed): AC 13, HP 45, Speed 30 ft.
STR 15 (+2) | DEX 13 (+1) | CON 14 (+2) | INT 11 | WIS 12 (+1) | CHA 10
Spear: +4 to hit, 1d6+2 piercing.
Pyrrha
NPC · Island Survivor · Neutral Good
Appearance: Mid-30s, dark-haired, lean and weathered. Moves quietly; keeps her back to walls. A deep scar on her right arm from a lamia's claws six months ago.
Personality: Fearful but pragmatic. She has survived on the island by staying out of the ruins and living off fish and rainwater. She wants off this island desperately and will help the party in exchange for passage.
What She Knows: A safe route through the saltmarsh to the temple. Locations of the Polished Bronze Mirror (collapsed altar) and Stonechill Water vials (urn near cave steps) in the ruins beyond the marsh. The cave has "a pool that glows like moonlight."
DC 12 Persuasion / Promise of rescue: Guides the party to the marsh crossing.
DC 14 Persuasion: Reveals item locations in the temple ruins (between Encounters 2 and 3). Describes lizardfolk patrol timing — advantage on initiative for Encounter 2.
Old Lysander, Priest of Apollo
NPC · Island Hermit · Neutral Good
Appearance: Ancient and skeletal-thin, with milk-white eyes. He lost his sight twenty years ago when he glimpsed Euryale's reflection in the pool during a failed exorcism attempt. He wears an Apollo pendant and carries a staff carved with sun-rays.
Personality: Cryptic and slow-speaking. He has meditated for years on the island's curse. He is not surprised by the party's arrival — he expected it. He believes Apollo guided them here.
What He Knows: The Still Pool's power and danger. The layout of the cave (described from memory). The Blindfolds of Apollo, which he carries and offers freely. He will confirm the scroll's meaning if shown it.
DC 13 Insight (upon seeing the scroll): He pauses for a long moment, then says: "The pool is the secret. She will not look at it willingly. But you can make her look."
If asked how he knows: "Because I looked into it myself. And it showed me her."
Maren, the Marsh-keeper
NPC · Druid Hermit · Neutral Good
Appearance: Weathered woman in her 40s, marsh-stained robes, staff hung with dried reeds and charms. Eyes sharp despite her hermit's solitude.
Personality: Grateful but wary. Prefers solitude but hates what Euryale's curse has done to the marsh. Will aid the party if they respect the wetland.
What She Provides: 3× Fire Flask on recruitment. Spellcasting ally in Encounter 3 (init 8). Knows fire is effective against the Stone Queen's guardians.
DC 13 Persuasion: Joins the party.
DC 10 Nature/Arcana: Recognizing her as a druid grants advantage on Persuasion.
Mention marsh woman / Lysander's guidance: DC drops to 8.

Polished Bronze Mirror
Wondrous Item · Common · Requires one hand
A round bronze shield polished to a perfect reflective shine. The back is embossed with a relief of Athena's owl.
Properties
Indirect Viewing. The wielder can observe creatures and spaces around corners or behind them without exposing themselves to line-of-sight effects (such as gaze attacks).
Gaze Deflection. When the wielder views a creature with a gaze attack via the mirror's reflection rather than direct sight, they make the associated saving throw with advantage.
Reflection (Bonus Action). Angle the mirror toward a medusa within 30 ft. of a large reflective surface (e.g., the Still Pool). Make a DC 14 Sleight of Hand check. On success, the creature must make its own gaze saving throw against itself. Requires positioning within 30 ft. — DM discretion on line of sight.
Found: Under a collapsed altar in the inner temple courtyard (exploration between Encounters 2 and 3). Pyrrha can point the party here (DC 14 Persuasion).

The Still Pool
Environmental Feature · Encounter 3 · Cave of Euryale
A 15 ft. × 10 ft. pool of perfectly still water in the center of the cave floor, glowing faintly with cold aquatic light. It mirrors everything above it with supernatural clarity. Lysander carried water from it out of the cave years ago (see Stonechill Vials).
Properties
Indirect Viewing. A creature using the pool to observe a gaze-attack creature (via reflection) makes the associated save with advantage.
Mirror Surface. Any creature with a gaze attack that is within 30 ft. of the pool and in its line of sight must make its own gaze saving throw against itself at the start of its turn (as per Mirror Vulnerability).
Euryale's Weakness. Euryale knows this danger and actively avoids line of sight to the pool using her Legendary Move action. Forcing her to face it requires maneuvering, deception, or a successful DC 14 Sleight of Hand check with the Polished Bronze Mirror to reflect her gaze toward it.

| Maren knows Euryale's serpent-crowned guardians are vulnerable to sustained flame — radiant and fire damage prevent undead reformation in the ruins ahead, and fire breaks lamia concentration reliably. |
| Encounter 3 benefit: Maren opens with Flaming Sphere (2d6 fire/turn) and can cast Heat Metal on armored foes. Her fire coverage gives the party a reliable tool against Euryale's minions. |
| Provided by: Maren when recruited; she volunteers this if the party mentions the temple or the cave. |
