The elite of Stormreach pay thousands of gold pieces a year to ensure security for their enclaves and manors, but one notorious cat burglar has found ways around every defense. This masked culprit is known only as the Stirge. More than a few suspicious souls have seen the incredible acrobatic performances of Nat Gann, dancing from pole to pole with the grace of a cat, and some whisper the acrobat is none other than the Stirge himself. The PCs might be hired to track down the Stirge by someone he burglarized, or they might hire the talented thief to acquire an item beyond their reach or to supply them with a detailed plan to infiltrate a stronghold.
