The ultimate act of chaotic retaliation arrived: Zariel, enraged by the destruction and collection of the Asmodeus artifacts, had transported Bromocorah's guildhall directly to Avernus, the first layer of the Nine Hells. The stone structure was now cracked and embedded in scorched plains, surrounded by lava flows and impaled souls.
Inside, the guildhall was a chaotic war room. Demit and Kilionzel saw this as less of a disaster and more of an opportunity to wreak pure havoc. Demit tasked the party with a reckless mission: infiltrate a nearby fortress and sabotage a critical infernal war engine to disrupt Zariel’s Blood War campaign. Kavar worried desperately about his daughter Luna's safety back in Waterdeep, while John's Oath of Devotion clashed wildly with the guild’s lawless plans.
During the chaotic briefing, two disguised figures, Karlach and Wyll, infiltrated the meeting. They offered covert support, revealing the war engine's location and providing a Hellfire Map—an instant tactical advantage for the unorganized crew.
The party set out across the hellish landscape. Their path immediately took them to The Lava Scar—a trench of bubbling lava crossed by a chain bridge.
Deep inside the fortress, they reached the Hellforge Lock, a fiery chamber guarding the massive hellforge gate. The lock was operated by three levers (Flame, Chain, Skull) that had to be pulled in the correct sequence, reflecting Zariel’s war machine domains: Destruction, Bondage, and Sacrifice.
The final battle took place in the Hellforge Crucible, a massive chamber surrounding the towering infernal construct—Zariel’s war engine. The chamber was encircled by lava moats and guarded by a mighty Pit Fiend commander, two Bearded Devils, and three harassing Imps.
