Immacolata: A cold, ruthless sorceress, who was exiled by her own race for practising evil magic and desiring too much power. Already exceptionally gifted by the standards of the Seerkind, Immacolata is also a possessor/avatar of The Menstruum - a subtle, powerful and seemingly sentient form of magic that manifests only in women and differently with each individual - where Suzanna's is described as a heavenly silver light Immacolata's takes the form of her own weaponised blood. Introduced as the main villain of the first half of the book she has many aspects associated with the wicked witch trope such as avoiding sunlight and a predilection for surrounding herself with bones/body parts. Unlike her ally Shadwell, Immacolata acts out of revenge with no desire for personal gain. In achieving her goal she unwittingly brings about her own undoing when Shadwell betrays, humiliates and kills her.
