<em>"The chimneys..."</em><br/><br/>As the hollow voice lets out the last answer to the question, before slumping back down and being extra dead. Which is a rather interesting answer, all things considered. The warrior woman that was raised by dwarves know about the deep forges that usually come with mithril mines, and how they are usually filled with smoke, heat, and more smoke. So guarding those holes in the ground is a rather non-starter, since anything going in will choke to death before getting ten feet.
