Dorn's Deep

From where she is, Alalla can see a handful of furnaces flowing brightly, each one tended by a giant working meticulously on some project. Every furnace she can see has some sort of massive piping that sprawls toward the middle of the room - presumably to some central forge.

As the party moves into the huge cavern, the fire giant guard watches them pass with a wary eye.

Maralie leads the way forward. Catwalks, bridges, every step is accompanied by intense heat. In moments each of the companions is covered in sweat. The fire giants, to no surprise, seem unbothered. The heroes even notice one giant reach down into the lava with a bare arm, completely at ease in the incredible heat.

Eventually the party nears the middle of the cavern and finds some stairs going down to a passage underneath the lava lake. Zenithral recognizes the hallways hear, and knows his mother's room is nearby.

Maralie guides them to a large room, at the far end of which stands a raised dais with a throne atop it. Behind the throne is an enormous furnace, far larger than any of the others above.

And there is Malavon.

Reòthadh recognizes that these golems are made of iron. There are signs of master craftsmanship (certainly forged by the fire giants), but these constructs are obviously unfinished. They seem to have been meant as practice pieces, to be set aside when work begins on the final product.

Still, they do seem to be animated by magic and at least somewhat functional. They are surely capable of killing helpless slaves.
