Zin-carla (spell)

Zin-carla is a practice of the drow, given only to those who have most pleased Lolth the Spider Queen. Zin-carla is a spell that can give the dead life, if one would call it that. It is more of a trance in which the corpse does the bidding of a particular person, in this case probably a high priestess of Lolth. Zaknafein Do'Urden, weapons master of House Do'Urden, ten years after being killed in sacrifice to Lolth, is reanimated in this grisly way.

Exile
In the book Exile by R.A. Salvatore, Shi'nayne, Vierna Do'Urden and the others of the house have gathered. At the last moment, right before Matron Malice is about to kill Rizzen Do'Urden, Malice stabs Shi'Nayne, actually Matron SiNafay through the heart. Lolth is pleased. At that moment, going a bit too far, the Matron Mater orders zin-carla, so she can send Zaknafein out to destroy Drizzt Do'Urden, who betrayed the family ten years ago. The yochlol present gasps and tells her she's gone too far, but eventually agrees. The priestesses of House Do'Urden must work for weeks before they can send Zak out hunting. Zin-carla makes Zak do things he wouldn't normally, and he kills many of the inhabitants of the Underdark before he reaches Drizzt in Blingdenstone.
