The Dark Stalkers of Faerun
At this time the Shadow Thieves are one of the largest criminal guilds operating out of the Sword Coast. They have a piece of almost all illicit trade in western Faerun, yet who they are and how they are organized is still a mystery. In 1373 DR, the Masked Lords of Waterdeep were able to push them out of the City of Splendor, but it now appears that they have infiltrated again, which means the Shadow Thieves guild now have a presence in every major city in the Sword Coast.
Currently, the Dark Stalkers have been unwillingly enmeshed in Shadow Thieves dealings. They hope that if they can just complete this “favor” that they will be left alone.
