The Opening

“A sealed parchment waits in your quarters, its wax stamped with the hammer-and-star of Anvilheart Citadel. Runemaster Brundin Axebringer begs you to reach Deepstone Mine, where a collapse has buried dwarven miners and awakened something beneath the mountain. In return for their rescue, he offers the soul-anchor crystal, a living shard of the shattered Nova’s Heart, and the runemasters’ finest starsteel work.”

Set the Scene

The letter is waiting after the party’s return to Dawnvale from Heartwood Bastion. Its parchment smells faintly of hot iron and pine ash. The seal breaks beneath a thumb, revealing a cramped but precise hand: Brundin Axebringer describes a collapse in Deepstone Mine, missing miners, and a crystal whose pulse has begun shaking the mountain. He asks the heroes to report to Anvilheart Citadel immediately, where a rune-marked escort will be waiting beneath the great dome of living stone.

Runemaster Brundin Axebringer

A sealed emergency letter arrives in Dawnvale several days after the party returns from Heartwood Bastion. Brundin’s messenger, a soot-streaked young courier named Hadrik Flintstep, can answer basic questions but insists that the full terms must be discussed at Anvilheart Citadel.

Rumours

d5 · table
  1. 01
    Deepstone Mine was sealed once before, after a starsteel vein began whispering the names of the dead.
  2. 02
    The Kharbal runemasters can make any weapon strike like falling iron, but only if the mountain accepts its wielder.
  3. 03
    A miner who escaped the collapse claimed that the stones were moving against the sound of his heartbeat.
  4. 04
    The Obsidian Tribunal has been asking questions about old dwarven soul-binding techniques.
  5. 05
    The deepest forge was built before the Kharbal clans united, and its original makers left no names behind.
Stakes

If the party fails, the trapped miners die or remain sealed below, the fourth Nova Heart shard remains vulnerable to Azkhar’s agents, and the unstable leyline threatens Anvilheart Citadel’s starsteel forges. If the heroes succeed, the Kharbal Holdfasts become a major ally and the party gains both a shard and evidence that the Obsidian Tribunal is hunting the Nova Heart through old soul-binding technology.

Ticking Clock·The mine will fully collapse after roughly 18 hours of in-world time. Each major delay, failed hazard challenge, or loud destructive action advances the collapse. If the party spends too long resting below ground, the miners’ chamber seals and the crystal chamber begins to rupture by the time they arrive.

Background Lore

Deepstone Mine was once the first starsteel forge beneath Mount Karghal, where ancestral runemasters learned to draw celestial metal from the mountain’s bones. When the Nova’s Heart shattered, its fourth living shard pierced the mine and lodged within an ancient soul-anchor crystal. The shard has awakened dormant runes, twisted the mine’s stone guardians, and destabilized the tunnels. The collapse has trapped a mining crew while the corruption spreads toward the lower forge galleries and threatens Anvilheart Citadel’s leyline channels.

What the World Knows

Deepstone Mine, an old Kharbal starsteel operation beneath Mount Karghal, has collapsed after a violent leyline tremor. Several miners are trapped, and the mine’s ancient defenses have begun attacking anyone who approaches the lower galleries. Runemaster Brundin Axebringer asks the heroes to rescue the dwarves and recover a powerful crystal lodged in the deepest forge chamber, promising runic enhancements and a valuable alliance with the Kharbal Holdfasts.
