Ylva was a member of the Scyre clan. She was the mother of the only child in the clan, Frey. After Scyre matriarch Phasma left together with her warriors in order for her to help General Brendol Hux reach his fallen starship, the clan's leader Keldo led his people and his allies in a pursuit of his sister. The two groups met at the fallen starship, where they fought. In the midst of battle, Siv killed Ylva, an action she later regretted.
