Seven Kingdoms: Seowyn's Crossing
Ylva was a young child who was kidnapped by Ogres in Norhast. The Three Sisters were hired by the girl’s family to either rescue her or avenge her death. They happened upon the caravan of Dagmar Gildenwell as the Fire Wasps were helping rescue it from the same ogres. After helping to destroy the monsters, their lair was found to contain her bones, which the Sisters delivered home to her family.
