This is a study of the effectiveness of not the individual but a group of individuals. This is an Open Ended Plot which will not be fleshed out by a single person but by who ever chooses to add content.
The peaceful sounds of mid afternoon were brutaly interupted by the swears and jeers of a fight erupting on the edge of the market near an alleyway. Seeing three armored humans fighting a young boy, the fight seems a bit unfair. Not seeing anyone rushing to the aid of the elf and with no watch in sight, the elf doesn’t seem to have a chance. Cries of thief echo from the lips of the three humans.
In a crowded marketplace, a man is standing on a soapbox, orating. Some of the crowd are cheering, some hissing, some standing around saying "I can't hear a bl**dy word he's saying". It's a hustings for an election. The PCs can either leave, or stay and listen. If they do the latter, then they can vote too, and they might get quite involved in the cheering. Depending on who wins they might get quite involved in the post-election brawl too...
There are numerous possibilities with this encounter: the PCs might end up talking to one of the nervous candidates before their speech, and offer encouragement and support. Of course this candidate may well turn out to be someone with outspokenly unorthodox views, and the crowd don't take kindly to s/his supporters. Or maybe the seemingly innocuous candidate turns out to be a complete racist, and the PCs wander off embarrassedly, pretending they weren't talking to this person five minutes ago.
