Mask is the calculating, mysterious god of shadows, thievery, and thieves in the Dungeons & Dragons Forgotten Realms setting. Ed Greenwood created Mask for his home Dungeons & Dragons game, loosely inspired by the Greek deity Hermes. Mask is a Neutral Evil Lesser Power whose symbol is a black velvet mask tinged with red. His divine realm is Shadow Keep in the Plane of Shadow, and his Third Edition Dungeons & Dragons domains are Darkness, Evil, Luck, and Trickery.
