Then central feature of the forge wastes is Vulcan's Forge - an enormous mechanized volcano, named after the first spark to find it - and the first (known) spark to die on its slopes (from, in this case, an unexpected pressure release valve that blasted most of his party with aerosol lava). The tremendous heat of the central Forge powers several massive steam turbines, and is believed to be the primary energy source for the entire forge wastes area - or perhaps even Tulthin as a whole. Reputable excavators mostly stay out of the forge wastes; it's simply too dangerous to be worth the trouble.
Speaking of which, any excavations require a permit, and the submission of detailed records of exactly what was recovered from where. There is, however, a tourist clause: you don't need a permit for picking up parts below a certain weight per unit time. In theory, these records are available to the public. In practice, however, there always seems to be one more form you need to fill out, or one more approval you have to wait to receive.
