Mask (pronounced MASK), the Lord of Shadows, is a loner god, most often associated with thieves or those of otherwise ill-repute. He is a neutral evil Intermediate deity, from the Shadow Keep in the Plane of Shadow, whose portfolio includes shadows, thievery and thieves; although it previously also included intrigue. Mask’s symbol is a black velvet mask tinged with red.
Known for his constant scheming, cool head, and oft reserved biting comment he has recently lost a significant portion of his power, the intrigue portfolio, to Cyric. This has, of course, led to two things: an enduring hatred of Cyric, and the Lord of Shadows leading himself to be more direct than he was in his prior, elaborate plots.
The church of Mask states that wealth rightfully belongs to those who can acquire it. Honesty is for fools but apparent honesty is a very valuable thing while subtlety is everything. Priests of Mask are known as the Circle of the Gray Ribbon.
It is rumored that the Cult of Mask maintains a large network of informants throughout the cities of the realm. It is also rumored that this network provides employment for all sorts of thieves, beggars and thugs

Simply put, Mask is a loner. However, in the past he has had frequent, presently infrequent, alliances with Bane. If nothing else, their sizable hatred of Cyric gives them a common ground in addition to their history of working together. Mask is also at direct odds with Waukeen, the goddess of merchants and honest trade. All guardians of light, knowledge, and duty are opposed to him. This includes Selûne, whose light tends to reveal his own faithful whilst they work.
During the Time of Troubles Mask took shape of a powerful blade called Godsbane. He would eventually come to be wielded by the then-mortal Cyric; he acquired the sword by murdering a halfling named Sneakabout, who in turn killed the former wielder of the sword. In the years following the Time of Troubles, Mask released the powerful hound Kezef to try and kill Cyric, but the hound turned instead on the Lord of Shadows, not stopping the chase until it had bitten off one of the god’s limbs. Mask, seemingly too weak to heal, acquired the powerful weapon Houndsbane to defend himself, the weapon, a gift from the deity of magic, Mystra.
