A resident of Phandalin, Mirna had a husband named Thel, and two children, Nars and Nilso.
Mirna's husband, Thel, was killed by the Redbrand Bandits as he stood up to the thugs. She and her children were taken to the Redbrand Hideout where they were kept in pens. They were eventually saved by The Party, and Gunter personally escorted them out of the hideout. She rewarded Gunter by telling him of her family's old shop in the ruins of Thundertree, where he could find a valuable piece of jewelry.
