Iggwilv

Iggwilv, also known as Tasha or Natasha, was an Oerthian archmage and demonologist. She wrote the Demonomicon of Iggwilv, a tome on demonic lore.

Relationships
Iggwilv had many confusing relationships with the demon prince Graz'zt. They were both lovers and enemies, their relationship constantly changing. Iggwilv, along with Mordenkainen and Elminster, was one of the most powerful archmages in the multiverse.

The witch queen was an enemy of the Nine Hells, owing to her partial interest in Graz'zt. She had a quasit familiar, who acted as a spy for the evil queen. She was very wealthy, and had mansions throughout the material plane, the Abyss, and Hades. Each was guarded by an army of dretches, manes, and shadow demons.

Spells
Iggwilv was credited with a number of spells, most of which were described in the Demonomicon. Her spells included:


 * Tasha's hideous laughter
 * Dolor
 * Ensnarement
 * Exaction
 * Imbrue
 * Implore
 * Minimus containment
 * Torment

History
Iggwilv was born in the world of Oerth and was the adopted daughter of the witch Baba Yaga, at which time she was known as Natasha "the Dark". She became known later as Tasha, before adopting her alias of Iggwilv, although it was not clear whether any of those was her original name. It was at that early point that she was credited with inventing the Tasha's hideous laughter spell, which by the late 15 century DR was commonly used throughout Waterdeep as a security measure against burglars, usually coupled with a glyph of warding cast on rooftops.

She later moved to the Niflheim layer of Hades.
