Lady Genna Lannister "Men are such thundering great fools. Even the sort who come along once in a thousand years." Tywin's only sister. Genna had close relationships with each of her brothers, and has a personality to match each of them. She was betrothed and wed to Emmon Frey by her father, a match ten-year old Tywin objected against. Nevertheless, she has grown into a strong representative of House Lannister who's council many respect.
