Re: Return to the Western Heartlands
The tunnel slopes down and down and down, running deep into the earth in almost a straight line until even Krackor is uncertain how far underground you are. The floor is bare, save for the cart tracks, and if it isn't dusty, it's merely due to the fact that there's no air movement with which to bring it. Though he's unable to determine how far down you're going, Krackor does spend some time analyzing the construction. This is definitely dwarven work; the way the passed is shored is very distinctive. But it's also old dwarven work. He's not exactly an expert on mines, but this shaft doesn't have as many refinements as the access passages he used to guard back in the old clanhome.
Between Corym and Krackor, your small group is able to advance in safety; quite confident that this tunnel is just as stable, and bare, as it looks. This is dwarven hard-rock mining, built to last for milennia, and so far doing exactly that. The iron torches continue, though the enchantments are failing at a much greater rate than in the level above. Only about one in six or seven is still burning, and the light flickers with more than just the movement of faux flame.
Eventually, in the light of a guttering torch up ahead, you can see the tunnel open into a room. There's been no branching, no traps, no hidden passages. Just one long, sloping shaft from one point to a second.
