This is when the consequences of the quest The Whispering Hillock are revealed leading to one of two endings for the Bloody Baron and his family:
Ending One – Head on back to the location where you encountered Anna, the children, and the Ladies of the Wood. Be prepared though, there will be a few fights with Drowners, Water Hags, and a large beast known as a Fiend. Though the quest comes with a suggested level of 9, if you aren’t really comfortable with dodging and using signs yet, don’t attempt the quest until you’re around level 11. If you killed the Ghost in the Tree, then you will discover that Anna has gone completely insane when you find her.
After taking care of all of the enemies in the area, the Bloody Baron will approach his wife. They will travel to the Blue Mountains where he hopes to find her the help she needs. It is as happy an ending as one can get in The Witcher 3: Wild Hunt.
