Hyacinth Drake

Hyacinth Drake is a vampire. She was turned (presumably to be with her husband).

During a confrontation with some Helios Ra agents, Hyacinth was hit with Holy Water (UV infused water) which burnt part of her skin (including the skin on her face), and she wears a dark veil to conceal the burns.

After she has been burnt by the Holy Water her great niece Solange saves her by giving her the blood of the ancient vampire Veronique Drake, which heals her to an extent and saves her life.
