Shops are places where the adventurer may purchase equipment for his quests,
and where he may sell his treasure if he should manage to survive the perils
with his life and sanity intact. Many shops trade only in a specific type of
merchandise. Thus, a baker may well refuse to buy your armor, even if it is
of high quality!
To some people, the prospect of obtaining the entire inventory of a shop by
murdering the keeper may appear tempting - but beware: The shopkeepers are
often rugged, capable men; roughened by years of trading and, indeed,
surviving in a world where the only safe prospect is death in the end.
