I've been thinking on this. She'll actually be pretty good at buffing people around her. A male warrior who can manage social interactions with nobility or similar might work. With all the children she's having, there is also room for someone to make a Gifted child if they want, though right now that would be a 1-year-old or one still in the womb. I had been debating if someone might make a companion of Sadb, but she's too tied to my maga and so is really better as a grog.
