Beneath the ruined golem manufactory of Kostryl’s Ironwrought Assembly, the Veiled Merchants gather to trade forbidden treasures. Madessa Vren hires the characters to acquire the radiant Gilded Egg of Shurraad, but her rival, Kelvos Marronis, offers a better deal with a dangerous catch. As masked bidders compete for cursed relics, the evening grows increasingly tense.
When the final lot is revealed, a traitorous doppelganger shatters the fragile peace. Aberrant magic sweeps through the auction hall, twisting guests into monstrous forms. Auction Master Faylen Kael responds by sealing the complex and unleashing his adamantine guardian, the Lockwarden, to eliminate everything inside.
With the exits sealed, the characters must navigate the ruined foundry and find a way to repair a sabotaged elevator using ancient dwarven components. Deadly glyphs guard the passages, while the Lockwarden hunts anyone who crosses its path. To escape, the party must decide whom to trust before the horrors below claim them all.
