Mask

Mask was the intermediate god of shadows, thievery, and formerly intrigue in the Faerûnian pantheon, a loner god most often associated with those of ill-repute. The Lord of Shadows was a chaotic neutral or neutral evil deity symbolized with a velvet black mask tainted with red.
Description Avatars of Mask within his temples usually appeared as slightly built human males wearing soft gray leather armor, a black cloak, and a black mask tinged with red (believed by scholars to be his true or chosen form). He might also manifest as a soft-spoken human female with pale, glowing skin, dark, floor-length hair, and starry white lights for eyes. This form always walked barefoot and was constantly shrouded in a shadow-like gloom. In public however, Mask's form was entirely inconsistent, appearing as members of all races, genders, ages, builds, and capabilities. No matter his form however, his movements made no sound and left no trail.
