The big quests and adventures may have the big rewards, but not every character is immediately able to participate in those, or they may have a bit of downtime that needs using up. This supplement has 100 small side jobs that characters could do. Most will not have any great reward; in some cases, the reward isn't, or isn't all, money, for these are jobs needed doing by the average person and smaller town.
That doesn't mean the jobs may not be problematical in one way or another. Some are requests for less than honest work, if you can read the code between the lines. In other cases, the situation may be more dire than the person requesting help believed, or perhaps their ends are more nefarious than they are making out.
