Result
The old woman looked much like the many other widows of Velen, though her eyes seemed to have seen even more hardship than usual. Perhaps that was because she was haunted by the ghost of her husband, who had died at war years ago. The ghost had asked the woman to bring her wedding ring to his grave. The cemetery was too far-off for an elderly woman to journey to, however, so she asked Geralt if he could make the trip for her. The witcher took pity and decided to grant her this somewhat unusual request.
