Return to Crookback Bog - The Witcher 3

As you recall, the self-proclaimed baron of Velen had asked Geralt to find his missing family. And so, ever a man of his word, find them he did. Tamara, the baron's daughter, he found in Oxenfurt, where she had joined the witch hunters. As for Anna, the baron's wife, she had been kidnapped by the Crones and made their slave, in fulfillment of a bargain she had struck with them earlier. Hearing this, the baron swore to free Anna, with or without the witcher's help, and set off to the place in the bog where Geralt had seen his wife.

Geralt decided to help the baron and went with him into the bog. There they ran into unexpected company: Tamara, accompanied by a band of witch hunters, had also ventured out in search of Anna.
They joined forces and, in the end, Anna was found, but, sadly, her mind was lost for good. Driven near mad himself with grief, the baron swore he would take his addled wife away from Velen and search the whole world for someone able to help her. As for Tamara, she and the witch hunters returned to Novigrad. And then... well, dear reader, the ultimate fate of the baron and his family is a tale for another time.

Geralt decided to help the baron and ventured with him into the bog. There they happened upon unexpected company - Tamara and a band of witch hunters, who had also set out in search of Anna.
They joined forces and found Anna, sadly turned into a terrible beast by a curse the Crones had cast. Geralt decided he would try to lift the curse and went to Johnny, the godling, for help.

And Johnny, as always, proved very helpful indeed. He revealed to Geralt that the Crones worked their magic in the basement of the hut with the tapestry. When Geralt and Graden descended into the basement, they found a collection of dolls with various items attached to them. They tried to reverse the curse by removing the doll that represented Anna, but their efforts ended in catastrophe - Anna burst into flames and died. Tamara returned to Oxenfurt following her mother's death, her spirits crushed. The baron, in no less foul a mood, went back to Crow's Perch. Geralt watched him walk away, wondering if he would ever see the man again.

And Johnny, as always, proved very helpful indeed. He revealed to Geralt that the Crones worked their magic in the cellar of the hut with the tapestry. When Geralt and Graden descended down into it, they found a collection of dolls with various items attached to them. They tried to lift the curse by removing the doll that represented Anna, but their efforts ended in catastrophe - Anna's curse was lifted, but she died soon afterwards, for the Crones had constructed it to leave death as its parting gift. Following her mother's death, Tamara returned to Oxenfurt, her spirits crushed. The baron, in no less foul a mood, went back to Crow's Perch. Geralt watched him walk away, wondering if he would ever see the man again.

In the end, Geralt decided he would look in on the baron. When he reached Crow's Perch, he inquired after the man but was saddened to learn he was dead. The lord of Velen had hanged himself, ending his reign and his sorrow.

In the end, the baron had only his own men to help him in his task. Geralt must have decided he had already done plenty by finding Anna and didn't want any more to do with the Crones than was absolutely necessary.

The witcher never saw the baron again. Perhaps the upstart lord of Velen died in the swamps while trying to find his wife - or perhaps he wanders there still to this day...
