In “Eldfjall’s Fury,” a party of 3-5 characters (levels 7-9) answers the call of Jarl Sigrid Frostdottir in the beleaguered port city of Stålhavn, where an unnatural heat is rotting crops, drying rivers, and driving the people to despair. The culprit is Surtursson — an exiled fire giant jarl who seized Mount Eldfjall after the dwarves of Berghjem abandoned their ancestral halls three decades ago. He has imprisoned Vindari, the elemental spirit of the North Wind, twisting her power to fuel his obsidian fortress and summon his kin. To free her, the party must journey across a scorched realm, earn the trust of the last dwarven smith, plunder a forgotten stronghold, scale a burning mountain, and face Surtursson in a three-phase battle at the summit. The adventure unfolds across five chapters.
Chapter 1: Call of the Jarl
The party arrives in Stålhavn — a port city simmering with tension, shortages, and desperate rumors of fire giants. After gathering what they can from taverns, market stalls, and the Shrine of the North Wind, they present themselves at the Jarl’s longhouse, where a gatekeeping captain first tests their worth. Inside, a seer lays out the full picture — Surtursson’s claim over the mountain, Vindari’s imprisonment, and the vital role of the long-abandoned dwarven halls of Berghjem — and sends the party into Shadowpine Woods to find the last master smith of that fallen people, equipped first with frost-shielding crystals and a map.
Chapter 2: The Last Smith
A long trek across scorched Járnmark tests the party’s endurance against extreme heat, worsened by heavy armor and the lack of water. Morning and evening encounters set the tone — fire-touched dire wolves, ash storms, giant patrols, the restless spirits of those the flames have already claimed, and an exiled storm giant who may yet become an ally. Two events demand real decisions: a punishing ash storm, and a band of desperate travelers whose fate the party must weigh. Shadowpine Woods offers a cool, dwarf-warded sanctuary at journey’s end, its own depths threaded with runic guardians, elemental riddles, and echoes of the dvergr’s exodus. At her frost-forged workshop, the master smith Grida Stonechanter studies the party closely before she will trust them — and the trust she grants opens the way into Berghjem.
Chapter 3: Halls of the Dvergr
The ancient dwarven stronghold of Berghjem, abandoned to fire and ruin, runs deep — chamber after chamber of hazards, guardians, and rewards. A warded entrance, a hall of animated stone defenders, a forge that still burns with residual magic, archives that hold the secret of Vindari’s binding and the giant’s weaknesses, and an elemental conduit that yields its boons only to those who understand it — all lead toward a treasure vault and, at the deepest point, a fire-corrupted iron golem guarding the one-way passage out onto the mountain itself.
Chapter 4: The Burning Mountain
The ascent of Mount Eldfjall unfolds across three brutal zones, each a fresh trial against the mountain’s worsening heat, steam vents, lava flows, and toxic fumes. The lower slopes wind through lava fields stalked by fire elementals; the crags demand a hard climb while magmin work to destroy the party’s ropes and gear; and the summit approach pushes through giant patrols straight into a battle with Surtursson’s vanguard before the gates of the obsidian fortress.
Chapter 5: Storm and Flame
Surtursson’s fortress can be entered by deception, force, or guile, and four areas stand between the party and the final battle. The entry hall and its lava channels are held by the giant’s elite warriors; the great forge can be sabotaged to strip Surtursson of his fire aura and weaken him for the fight to come; and Vindari’s prison can be broken to free the North Wind, who repays her rescuers with resistance to fire, the power of the wind, and counsel for the battle ahead. In the throne room, Surtursson fights across three escalating phases — and how strong he proves in the second depends entirely on whether Vindari still hangs in chains or stands free at the party’s side. In his final, desperate moments he collapses the floor itself, threatening to drop the whole party into the lava below. Victory restores the North Wind, quiets the volcano, and earns the party titles, land, Vindari’s lasting blessing, and a hoard worthy of the deed.
