Xanathar's Guild
The Xanathar’s Guild is a group of thieves and cutthroats operating out of the bowels of Waterdeep. From its main offices in Skullport, the Xanathar’s Guild has access to several portals, with prominent ones leading to an alley in Waterdeep, a rock outcropping near Calimport, and a small Guild-owned warehouse in Westgate.
The Guild is said to be led by an elder beholder called The Xanathar. Eleven Masters each control one of the Guild’s businesses: assassination, blackmail, book-keeping, enforcement, extortion, information gathering, magical defenses, mercenaries, slavery, smuggling, and thievery. Most of the Guild’s work involves slavery or thievery.
