Young women in the Women's Halls make their vows of sister-kinship on Spring's Eve, exchanging crocus flowers. It is at about this time of year that travel between the Keeps of the Riverland becomes feasible after the long winter, and Highborn women send their sister-kin vow gifts such as token cloths embroidered with the news of the winter season in the knot-stitch code.
