13A. An irregular-shaped outcropping
here is the source of flint for the kobolds (at
6) No large chunks of flint can be gotten out
without tools, but there are many tiny flint
chips about.

13B. There Is a vein of soft coal in the wall
at this point. It will be noticed only if a light
source is being used--infravision will not
differentiate it from the rest of the wall. If
tools are used, about 6 pounds of coal can
be dug from the wall; if no tools are used,
only 1 pound may be obtained. If ignited,
1 pound of coal will burn for 3 hours,
casting light in a 40-foot radius. Coal burns
much hotter than most combustibles, and
requires more than just a spark to light it
(i.e. a full fire is necessary).
