Mask is the mysterious god of shadows, thievery and thieves. His symbol is a black velvet mask tinged with red. He is depicted as wearing a cloak that allows him to fly, become invisible, and when the hood is placed up, appear as any other being in an impervious illusion. His domains are Darkness, Evil, Luck, and Trickery.
Worshippers of Mask tend to hold their services in dimly lit vaults, and the followers and priests all wear heavy garb and masks. Because of the clandestine nature of the religion, little to nothing is known about its current state in the Great Realms.
