The Opening

“A distress signal pulses through Dawnkeep’s ley wards, carrying the sound of grinding stone and distant dwarven voices. Stonefist Holdfast is collapsing, and Foreman Brunna Stoneheart begs for heroes to descend before the tunnels bury her people forever. The tremors are spreading toward the ancient leyline beneath the mine.”

— Hook · Rescue and subterranean disaster adventure

Set the Scene

Rain ticks against Dawnkeep’s slate roofs when the ley wards flare blue-white. The signal arrives as a vibration in the teeth, followed by a ghostly voice carried through the wardstones: Brunna Stoneheart calling from beneath the earth. By the time the party reaches Stonefist Holdfast, dust pours from the mountain like smoke, iron bells hammer through the tunnels, and dwarven workers drag the injured into the cold morning air while the sealed gate shudders inward.

Brunna Stoneheart

Brunna approaches the party at the cracked entrance gate with a lantern in one hand and a bloodied pick in the other. She gives a precise account of the missing crews, places a map of the mine in the party’s hands, and promises Stonefist’s gratitude if they bring her people back alive. Mora Thunderforger quietly warns that the Sigil of Stone must be handled with care, then asks the heroes to preserve any inscriptions they find around the Rune Wheel.

Rumours

    Some dwarves claim the mountain has been angry since a shipment of starsteel vanished from the lower galleries.
  3. 03
    The earth guardians were once protectors of the holdfast, not enemies.
  4. 04
    Mora Thunderforger has forbidden anyone from copying the runes found near the old mine lifts.
  5. 05
    A tremor was felt at Anvilheart Citadel shortly before Stonefist’s distress signal reached Dawnkeep.
Stakes

The lives of the trapped miners, the survival of Stonefist Holdfast, the security of a major Kharbal trade route, and the stability of a leyline beneath the Ironspine Range are all at risk. If the party delays, the lower galleries will collapse permanently and the awakened Rune Wheel may spread tremors into neighboring passes.

Ticking Clock·The collapse clock advances whenever the party fails a rescue or navigation check, makes excessive noise, or takes a long rest underground. After six advances, the lowest galleries seal, preventing further rescues and imposing disadvantage on attempts to reach the monolith. The clock can be reduced by stabilizing supports, using the holdfast’s emergency runes, or successfully coordinating Brunna and the rescued miners.

Background Lore

Stonefist Holdfast was founded around an ancient leyline anchor, sealed beneath the mine by a circular mechanism called the Rune Wheel. The dwarves believed its runes were part of the mountain’s natural warding system, but the device was designed to regulate subterranean earth-magic and prevent pressure from building along the leyline. Centuries of mining, forgotten repairs, and recent tremors have disturbed the mechanism. Now the Rune Wheel turns again, waking stone guardians and sending fractures through the oldest tunnels.

What the World Knows

Stonefist Holdfast is collapsing after a series of subterranean tremors. Foreman Brunna Stoneheart has called for outside aid because at least several mining crews remain trapped below. Ancient machinery has awakened in the deepest galleries, and earth elemental guardians now block the route to the Sigil of Stone, a relic believed to stabilize the local leyline. The heroes must rescue at least ten miners, survive the unstable tunnels, defeat the guardians, and recover the sigil before the holdfast is lost.
