Shar
Shar (pronounced SHAHR), the Mistress of the Night, was the goddess of darkness and the caverns of Versania, as well as a neutral evil greater deity. Counterpart to her twin Selûne, she presided over caverns, darkness, dungeons, forgetfulness, loss, night, secrets, and the Underdark. Among her array of twisted powers was the ability to see everything that lay or happened in the dark. Shar's symbol was a black disk with a deep purple border. Shar was also the creator of the Shadow Weave, which was a counterpart and attack upon the Weave of Magic, controlled by Mystryl and her successors, before both of the Weaves fell into ruin and mortals began to use Magic themselves.
