The Opening

Three people have vanished on the old mountain road, and the only survivor returned speaking in the voices of the missing. Mara Venn offers you a map to the forbidden Ashen Stair and asks you to descend, document what lies below, and recover her mentor's journal before the mountain opens again. She warns you that the tremors have already begun.

Set the Scene

The adventure begins in Bellwether during a cold rain. Mara Venn spreads a water-stained map across the table of an abandoned survey office while Orrin Pike sits nearby, staring at a wall where no door exists. Orrin insists that the missing surveyors are still alive below the mountain, but every few minutes he repeats a sentence in a different person's voice. Mara offers the party supplies, a rough map, and a promise of payment if they return with proof, not rumors.

Mara Venn

Mara Venn approaches the party in Bellwether's abandoned survey office after hearing that they have experience surviving dangerous wilderness or ruins. She is direct, practical, and willing to pay half the reward up front in supplies or coin. If questioned about the observatory, she admits that her mentor vanished there twenty years ago, but does not know that Brother Caldus helped reactivate it.

Stakes

If the party fails, the Deep Echo establishes a permanent connection to Bellwether and begins rewriting memories across the settlement. Even success carries a cost: the observatory contains knowledge that cannot be safely destroyed, and every surviving fragment may become the seed of another haunting.

Ticking Clock·The star-metal fragment will complete its alignment with the surface in three nights. Each major rest taken below the mountain advances the alignment by one stage. At the final stage, the Deep Echo can project itself into Bellwether and the party must resolve the crisis immediately.

Background Lore

For centuries, the Ashen Stair was believed to be a dead pilgrimage road descending into the mountain of Veyr. In truth, it leads to an ancient subterranean observatory built by the extinct Order of the First Lantern. The order studied a living star-metal fragment buried beneath the mountain, but their experiments awakened a reality-warping intelligence known as the Deep Echo. The observatory was sealed, its records scattered, and the road erased from every surviving map. Recent tremors have reopened the route, while creatures from below have begun emerging near the frontier settlement of Bellwether.

What the World Knows

The Ashen Stair is an ancient route beneath Mount Veyr that recently reopened after a series of tremors. Surveyors sent to investigate disappeared, and the sole survivor returned with fragmented memories and warnings about a voice beneath the mountain. Bellwether's cartographer Mara Venn asks the party to descend, map the route, investigate the disappearances, and recover the lost journal of her mentor. The party will face unstable ruins, hostile subterranean creatures, and a desperate cult that believes the buried observatory can return the dead.
