Chains the Grey

Chains the Gray is an elder human living in Waterdeep, and an apparent member of the mysterious Thieves' Guild residing within the city, along with being the adoptive father and boss of a quartet of orphans he bought from an acquaintance. He has an ongoing façade of being a priest of Tyr in a smaller chapel which he upkept in a lower class area, and used this façade to conduct spying, thieving and other illegalities. He actually follows the god Mask, Lord of Shadows, most often associated with thieves.
Chains used his quartet of orphans to make his work easier, and also because he feels a closeness to the downtrodden of society. He taught them useful skills depending on their natural talents, and they proved incredibly efficient in aiding his work.
Due to a mistake during a job, his façade and illegal actions were revealed to the authorities of Waterdeep, and likely due to a schism of some sort, the Thieves' Guild refused to bail him out. He now awaits his sentencing in prison.

Chains the Grey is the foster parent of Bene Lugosi
