Різа Бреннер

Number 11 of the Obsidian Table. A lady who always exhibits impeccable virtue and sagacity, yet in reality killed thousands of children through human experimentation in the name of her career.

Though she and Eleonore were old friends from their time in the BDM, the vast gap between their own values causes them to get along like cats and dogs.

Her Ahnenerbe is Pallida Mors, the Mask of Pale Death. It's comprised of two forms, a shroud made from the skin of children she once cared for that allows her to seize control of any number of undead in range, and a mask that she can put on a corpse to exert greater control over it and prevent its decay.
