Spite of the Harridan
Wives' tales of less enlightened times spoke of the ability of witchcraft to strike them barren, to steal children's breath and to leave them without issue. this ritual may be the origin of some of those stories. Invoking this power allows the thaumaturge to terminate any pregnancy, regardless of its stage, so long as the child is not yet being born. The caster must crush a snake's egg in her hand for this ritual to take effect.
System: This ritual must be performed in the presence of the subject, though she need not know that the thaumaturge is there. The pregnancy's termination is messy, obvious and often painful to the erstwhile mother.
