The Cove Behind the Falling Veil

Description

Adventure Summary

This campaign framework is designed for a party of 4-5 characters beginning at 5th level and ending around 8th or 9th level over 5-6 sessions of about 4 hours each. The story centers on a prosperous fishing town whose people are slowly losing treasured memories, names, skills, and pieces of themselves. Investigation leads to a hidden pirate cove concealed behind a roaring waterfall, where undead buccaneers gather under a feared captain who appears to be stealing memories for cruel and selfish reasons. The truth is darker: the undead raiders are maintaining a fragile bargain that keeps an ancient horror asleep beneath the cove. The campaign emphasizes investigation, moral choices, haunted exploration, shipboard action, and a final decision about whether some memories are too dangerous to preserve.

Background

Along a storm-bitten coast stands the market town of Greyglass, a harbor settlement built where black cliffs descend into a cold green sea. Generations ago the coast was ruled less by kings than by tides, merchants, and private fleets. Smugglers and corsairs used the surrounding reefs as secret roads, and among them none were more infamous than the crew of the Black Banner, a ruthless pirate company led by Captain Seressa Vane. Their hidden refuge lay behind an immense waterfall called the Falling Veil, where a sea-cut cavern opened into a sheltered lagoon invisible from open water. From there the pirates struck trade ships, vanished into mist, and buried stolen wealth in chambers cut into the cliff.

The Black Banner did not fall to a navy. It found something in the flooded caverns below its cove: an aboleth, ancient even then, trapped in brine-filled vaults from an age before the town existed. The creature, later called the Drowned Rememberer, could not fully escape its prison, but it could reach minds through dreams, water, and longing. Captain Vane sought to command it and instead doomed her crew. One by one they became bound to the cove by terror, greed, and half-understood pacts. When they finally died in mutiny, drowning, or desperate battle, many rose again as undead, unable to abandon the place or the thing below it. Over time their captain became less conqueror than jailer, preserving the prison with stolen will and stolen memory.

Now the prison is weakening. Earthquakes have cracked lower tunnels, old sigils have dissolved, and the aboleth has learned a subtler method of feeding: it reaches through underground springs into Greyglass and drinks the memories of the living. The town forgets songs, grudges, marriages, and routes through familiar streets. A child no longer remembers her mother’s face. A shipwright forgets how to shape a keel. A magistrate wakes unable to recall the name of his dead son and feels only the outline of grief. The undead pirates have begun stealing memories as well, but not merely for hunger. Captain Vane’s successor gathers memories into cursed reliquaries to keep the aboleth sated and dull, buying time in the only way she knows.
