“ Darklings are a kind of Halflings living in the sewer of medium to large cities.
Even though they smell badly and are quite dirty, Darklings are friendly and clever.
They try to limit the knowledge about their existence to only a small number of trustworthy persons, including player characters.
Darklings trade in information. Money, weapons and magical items have no value for them. This is why they hide beneath the sewer grates, listening to all that is said in the city above.”
“ Five men are herding fifteen horses down the road. They won't be very talkative, but are willing to sell a horse, or more horses if the heroes are interested. These men are horse thieves. They are already sought by regional militiamen. Anyone with a stolen horse (all are marked) may get into trouble. If found guilty, horse thieves face prison or even a hanging execution. Similar thefts have happened only a month before, and a reward is offered.”
“ The player characters, experienced and somewhat well known, hear rumors and travelers' tales about a distant area being overrun by dragons (or other terrifying monstrosities). The locals have sent them a message, begging for heroic aid.
When they investigate, they discover that nothing of the sort is going on. It turns out that a group of thieves wanted them out of the way so that they could rob them (or someone who would normally receive their protection).”
