Ylva's clan was the Scyre clan. She and Keldo, a leader within the clan, conceived a daughter. This daughter, Frey, was the only child among the Scyre. When the Scyre's matriarch, Phasma, departed with her warriors to assist General Brendol Hux in reaching his crashed starship (the fallen one), Keldo and his companions chased after her. A battle ensued at the starship when the two groups finally confronted each other. During this conflict, Ylva was killed by Siv, an act that Siv would eventually lament.
