Brotherhood of Dragons
Thieves Among Us!
As the players are wondering the market either looking for goods to buy/sell or looking for work, an angry group rushes through chasing a couple of halflings. If the PC's join the chase they will discover that the halflings are small time pickpockets. The individuals chasing the halflings are mostly patrons that have had purses presumably lifted by the pair. Use Bandits (mm 343).
The pair of halflings are part of a small time thieves guild operated out of the poor district in town. This will allow the PC's to make connections with the local Onsmill personalities.
