Kiaransalee

From Ardrana

Kiaransalee is the drow deity of both vengeance and the undead. She is called upon by those seeking retribution, the dark arts, or to prolong life. The Lady of the Dead has long chafed under Lolth's suzerainty, and only the Spider Queen's overwhelming strength has kept Kiaransalee's long-planned vengeance in check.

The Lady of the Dead is cruel, twisted, and consumed by thoughts of vengeance. Kiaransalee descended into madness long ago, but she retains her twisted cunning and clear recollection of every slight or insult done to her -- real or imagined. The Revenancer is powerfully chaotic and swift to anger, and she schemes dark revenges against all who have wronged her. Kiaransalee prefers the mindless company of the undead, whom she can manipulate at will, to sentient beings capable of independent thought. She prefers to solve problems herself rather than trust someone else to do justice to her vision.

Note: Kiaransalee originally appeared in this form in Demihuman Deities for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
