“ Dustwood is technically not a wood from a specific tree. It is an created fuel for fires.
Starting with the sawdust from a sawmill, adding a mixture of wax or pitch, and a few other things, the mixture is pounded or pressed toghether tightly. It is normally smashed into a round container, so when it is slipped out, it looks like a small perfectly round 'log'. (actually a lathed log, but you get the idea). It can either be used as a log or slices of a log can be used for a fire.”

The local band of 'nasties' (goblins / orcs / whatever) lives in relative peace with the local population.<br />
Along come the PCs and go through their usual heroic monster bashing routine, wiping out the nasties and pinching all their stuff, then continue on their way.<br />
Problem is, they don't kill ALL he nasties. The survivors want revenge and, after spending a few months recovering, start to take it in their own inimitable style (which is not unlike that of the PCs come to think of it).<br />
Next time the PCs are in the area they find themselves VERY unpopular with the townsfolk.”
