To recap:
Someone is killing Warforged.
Two locations were mentioned: the Cannith forgehold (with the bodies), and the Tain foundry (where they all worked).
You have a clue: a link of gold chain.
Morning lumbers over the horizon, or it would if you could see the sun. It's the start of another smoky day in the bowels of Sharn. Although Seeker and Reason are impatient, Melina eats a full breakfast before announcing that she's ready to proceed.
You start towards the Cannith forgehold. The streets are busier during the day, and it would be difficult to get through the crowd. That is, if you weren't following behind a 7-foot-tall Warforged Juggernaught. For some reason they get out of the way. "Everybody MOVE!" and all that. Melina just skips behind smiling.
You arrive at the Forgehold without incident. It is a small but luxurious building. Outside stands a silent, grim-looking warforged who does not respond to your greetings (think Queen's Guard). He is standing next to a open door, beyond which is a small atrium. A young woman wearing the livery of House Cannith sits at a desk, alternating between studying a sheaf of parchment and painting her nails.
