The Wreck of the Crimson Meridian
The Wreck of the Crimson Meridian
A merchant vessel has washed ashore on a remote island, and its cargo of rare spices—worth a king's ransom—has vanished. The party must investigate the wreck, interview the traumatized survivors, and uncover whether the crew was betrayed by one of their own, or if something far more sinister emerged from the depths. The mystery deepens when they discover the ship's manifest doesn't match the cargo that was supposedly lost.
Read Aloud
You trudge through black sand toward the splintered remains of the merchant ship Crimson Meridian, its broken hull tilted at an awful angle against the reef. Gulls scatter at your approach, revealing deep gouges in the wooden planks—not from rocks, but from something with claws. The air reeks of brine and rot, mixed with an acrid sweetness you can't quite place. Near the shoreline, a makeshift camp of tattered canvas shelters houses the survivors: a handful of crew members who watched their fortune sink. An older woman in a captain's coat stands apart, wringing her hands and staring at the wreck as though willing it back to wholeness.
Description
The party arrives at the cove where Captain Meridian's ship has run aground. The beach is strewn with cargo containers, broken barrels, and salvage. Most notably, several cargo boxes bear the insignia of House Valorian (a merchant consortium), but they are conspicuously empty. The survivors—five crew members and Captain Iris Meridian—are camped here, desperate for aid. The captain is distant and evasive when questioned directly. A DC 14 Wisdom (Insight) check reveals she is hiding something significant. The ship's hull shows damage consistent with a violent impact on the reef, but also inexplicable claw marks and what appears to be acidic scoring on the wooden frame.
DM Notes
This is an investigation hub. The survivors are willing to talk, but give contradictory accounts. Encourage the party to ask open-ended questions. DC 12 Insight checks reveal which crew members are lying about what they saw. Captain Meridian will reveal (under pressure) that she ordered the ship altered course the night before the wreck—but won't initially explain why. There is a ship's manifest wedged in the sand near the captain's tent; it lists spices worth 2,000 gp, but nearby crates are labeled as containing "surgical instruments" (worth far less). This discrepancy is the key to the mystery. Allow the party to gather clues at their own pace before moving to Scene 2.
Secrets Below the Waterline
Read Aloud
The tide is low. You descend into the shadow of the Meridian's broken stern, salt-slicked rocks treacherous beneath your feet. Inside the hull, the air is thick and humid. Bioluminescent fungi cling to the wooden beams—not natural growth. They pulse faintly with an eerie cyan light. Deeper in, you find the captain's quarters ransacked. Charts are strewn about, stained with what appears to be seawater and something else—a faintly luminescent slime that smells of sulfur. On the captain's desk, a ledger lies open, its pages filled with two sets of handwriting: one is Captain Meridian's, the other is unknown.
Description
The party investigates the wreck's interior. The second handwriting in the ledger belongs to Tertius Kael, the ship's supercargo (cargo master), and it documents secret transactions with representatives of the Abyssal Consortium—a smuggling ring operating out of the nearby settlement of Siren's Rest. The ledger reveals that the "spices" were cover for something else: enchanted artifacts bound for a cult operating in the Underdark. The bioluminescent fungi are a calling card—a signature of deep-sea entities. However, the most crucial detail is a note in Meridian's hand: "Cannot continue. T.K. has gone too far. Must scuttle the shipment before we reach port." The party can also find the captain's personal log, which reveals she was coerced into the scheme when the Consortium threatened her family, held in Siren's Rest.
DM Notes
This scene is a clue-gathering exercise. The bioluminescent fungi can be identified with a DC 13 Arcana check or a DC 14 Nature check—they're from the Underdark. The ledger requires DC 10 to read (it's written in common). Encourage the party to piece together the conspiracy. If they ask about Tertius, Captain Meridian (back at camp) will admit he fled into the island's interior the night of the wreck. The note about "scuttling the shipment" is ambiguous—did she deliberately sink the ship? Or was the Consortium responsible? This uncertainty is key to the mystery's depth.

Tactics
Tertius uses the jungle terrain to his advantage, employing hit-and-run tactics and commanding his cultist allies. He has access to spells (treat as a 5th-level caster with divination and evocation spells: Scorching Ray, Magic Missile, Misty Step). The cultists are fanatics who attempt to create barriers and buy time for Tertius to escape deeper into the island. Tertius will attempt to negotiate or flee if reduced to half HP, revealing information about the artifacts' intended location (the Sunken Temple of Zyx'thar, reachable via underwater passages three leagues northeast) if he senses the party is overpowering him. He will not go down without a fight—he has invested too much in the mission.
Terrain
Dense jungle with tangled roots, dense undergrowth (half cover), and massive stone ruins overgrown with vines—remnants of an ancient civilization. The encounter takes place near the ruins. Use the ruins as blocking terrain. A small tributary of brackish water runs through the area, creating opportunities for tactical repositioning.
The Truth in Captain Meridian's Study
Read Aloud
Back at the camp, Captain Meridian sits by a driftwood fire, her shoulders slumped in defeat. When you approach with news of Tertius's betrayal and flight, she finally breaks. Tears stream down her weathered face as she confesses everything: the Consortium's threats, her daughter's captivity in Siren's Rest, the false manifest, and—most importantly—the true nature of the artifacts. They are not mere treasures. They are three Obsidian Keys, ancient reliquaries carved from stone that fell from the stars. Alone, they are worthless. Together, they unlock the Sunken Temple of Zyx'thar, where the Consortium plans to resurrect something that should have remained buried.
Description
Captain Meridian reveals the core of the conspiracy. The Abyssal Consortium is working toward summoning or awakening an entity called the Star-Drowned God, an entity of cosmic horror that lies dormant in the Sunken Temple. The three Obsidian Keys are required to open the temple's innermost sanctum. She deliberately ran the ship aground to scatter the keys and buy time. One key went down with the ship (currently resting in the hold, accessible to the party if they retrieve it). The other two keys were supposedly aboard cargo containers that Tertius claimed were lost—but the party now knows he recovered them. Meridian does not know where Tertius was taking them, but she provides coordinates to the general location of the temple based on nautical charts Tertius left behind. She also gives the party a final clue: her daughter, Mara, works in the Consortium's operations in Siren's Rest and may be a valuable contact or ally.
DM Notes
This scene is the revelation moment. Allow the party to process the information and ask questions. Meridian is truthful now, having nothing left to lose. Provide her with emotional depth—she is not a villain, but a desperate mother who made terrible choices. If the party offers to rescue her daughter, she will be profoundly grateful and provide additional information: Siren's Rest is a settlement nominally under the control of a corrupt harbormaster named Vex Quillan, but the Consortium controls the actual power structure. She can provide names and descriptions of key Consortium operatives. If the party does not ask about her daughter, she will volunteer this information herself, begging them to help. This sets up a hook for the next session.
Treasure & Rewards
A three-foot-long shard of black stone carved with arcane runes. Warm to the touch and faintly thrumming with power. This key was recovered from the Crimson Meridian's hold. It is inert without the other two keys but radiates an aura of ancient magic.
Tertius Kael's handwritten account of the conspiracy, including meeting locations in Siren's Rest, the names of three Consortium operatives, and nautical coordinates to the Sunken Temple of Zyx'thar. Invaluable intelligence for future operations.
A silver ring inscribed with Abyssal script. If the party defeated or captured Tertius, they recover this item. The ring is a token of rank within the Abyssal Consortium and grants advantage on Charisma (Deception) checks when dealing with cultists—if they know about it. Worth 150 gp if sold, but its true value lies in the information it conveys.
Captain Meridian offers the party her personal savings (250 gp) and a fine captain's cloak that grants the wearer advantage on Acrobatics checks made to climb or traverse difficult terrain. She has little else of value, but this gift represents her gratitude and desperation.
Story Hooks
The first Obsidian Key is now in the party's possession, but two remain hidden with Tertius or scattered across the Underdark. The Abyssal Consortium is now aware the party is interfering with their plans and will likely send agents to pursue them. Captain Meridian's daughter, Mara, is still a hostage in Siren's Rest—rescuing her could yield crucial information about the Consortium's operations and the location of the remaining keys. The Sunken Temple of Zyx'thar awaits discovery, and the party must decide whether to pursue the keys before the Consortium can retrieve them all.
Conclusion
Wrap Up
The party pieces together the conspiracy: Captain Meridian was coerced into transporting artifacts on behalf of the Abyssal Consortium, deliberately wrecked her ship to prevent the keys from reaching their destination, and has now revealed the Consortium's true goal—to unlock the Sunken Temple and awaken something ancient and terrible. The immediate mystery is resolved, but the larger threat remains unresolved. Captain Meridian is freed from her burden of secrecy and can begin planning a rescue for her daughter, Mara. The survivors of the Crimson Meridian are grateful to the party and offer to provide passage to Siren's Rest if needed, or to carry word of the party's deeds to other settlements along the coast.
Cliffhanger
As night falls over Broken Anchor Cove, the party notices strange lights moving beneath the waves offshore—bioluminescent shapes moving with purpose toward the cove. They are not fish. They are humanoid forms, webbed and alien, emerging from the depths in increasing numbers. One of the survivors screams: "The Deep Ones! The Consortium called them! They're here for the key!" The beach erupts into chaos as an otherworldly force rises from the ocean.
Next Session Hooks
- Rescue Mara Meridian from the Abyssal Consortium's operatives in Siren's Rest before she becomes a liability or a hostage used against the party.
- Recover the second and third Obsidian Keys before the Consortium can retrieve them, or learn their location by interrogating Tertius or other cultists.
- Investigate the true nature of the Star-Drowned God and determine whether the Sunken Temple should be sealed permanently or explored for knowledge that could save the world.
