Geralt encountered this young womans ghost in the uppermost room in the haunted tower on Fyke Isle. She told him that in life she had been the local lord's daughter.
When enraged peasants stormed the tower, she feared they would ravage her honor if they found her alive and so took a magic potion that put her in a corpse-like state of paralysis. When she awoke, she found herself lying amidst the bodies of her family and servants, unable to move. She watched in helpless horror as rats feasted on the pile of corpses and began to nibble on her as well.
This grisly death must have somehow put a curse on her and the tower, for her ghost had wandered it in restless torment ever since, Geralt engaged his vast experience with such curses to search for a possible solution. Having learned that Anabelle had lowed a simple fisherman named Graham, Geralt decided this man and the bond of true love the two youths shared could be their salvation.
Geralt agreed to take the young womans remains to her love to have him give her a proper burial. Geralt hoped this would lift the evil spell on the cursed isle and bring
Anabelle peace at long last.
