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 a more advanced form or reanimation where the reanimated corpse is not simply a mindless zombie, but retains all the capabilities it had while it was alive. The corpse is also bound to do a single task, chosen by the person that reanimated it and approved by Lolth. To give the corpse the abilities it had while it was alive, the spirit of the person who the corpse belonged to in life is called to inhabit the body, but is given very little control over the corpse's actions beyond the use of its abilities. Zaknafein Do'Urden, weapons master of House Do'Urden was reanimated in this grisly way ten years after being killed in sacrifice to Lolth.

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 Mother 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.
