The Fall of the House of Reardon is a secondary quest in The Witcher 3: Wild Hunt. The quest is given when Geralt meets an old lady in Lindenvale, named Dolores, as she's kicked out of someone's hut or by finding her notice on the nearby notice board. She returned to the area after her husband passed away and was looking to move back into her family's estate, but the place is supposedly crawling with monsters. She'll then ask Geralt to help her.
