A letter is sent to a specialized group of people: 

"Shadow walker. Sticky fingers. One of many faces. This letter finds you for one purpose: A five-finger discount for an unsuspecting victim. If you want to make some coin and prove your skillset there's no happier place than a tavern bovine."

((This DM event is open only to rogue PCs between levels 2-10. Multiclass PC's need at least 2 levels of Rogue to qualify. It will begin on Friday September 23 at 4:00pm EDT. Anyone interested can gather in the Happy Cow Tavern in Escalant West at the designated time.))
