Chronicles of Khaldun: Crux of Eternity
The drow goddess of death, vengeance, and slavery, Kiaransalee is considered a lesser goddess among the drow, one with a secretive cult. Alternately known as The Lady of the Dead, The Revenancer, The Vengeful Banshee, and The Pitiless Dowager, Kiaransalee teaches that death should be revered, for it comes for us all. All debts must be repayed, all slights unforgiven, all must bend the knee and serve.
Of course, Kiaransalee is currently a dead deity: the Shields of the Sorrowfell infiltrated her stronghold and discorporated her. As such, her throne is empty and she answers no prayers. Interested parties can read of her demise here.
