The Shadowmasters of Telflamm were a thieves’ guild that operates throughout the east of Faerûn. Their headquarters were located in Telflamm, where they rule the city in all but name. It is unclear to which diety the leadership is devoted.
There is a long ongoing feud between The Shadowmasters and the yakuza style group known as the Nine Golden Swords. Certainly, any move to take a step closer to the stronghold of the Nine Golden Swords in Phsant will be opposed by the Shou organization.
Recently there have been rumors that they are making in-roads into the leadership of Phent. Most are convinced these are only rumors, but recent evidence shows these rumors are anything but false. One recent event is the attempt on the life of Ugadesh which was thwarted. It is yet to be seen what the results of this brazen attack might yet be with regard to the city of Phent.
